Abstract
Life tables are one of the most common tools to describe the biology of insect species and their response to environmental conditions. Although the benefits of life tables are beyond question, we raise some doubts about the completeness of the information reported in life tables. To substantiate these doubts, we consider a case study (Corcyra cephalonica) for which the raw dataset is available. The data suggest that the Gaussian approximation of the development times which is implied by the average and standard error usually reported in life tables does not describe reliably the actual distribution of the data which can be misleading and hide interesting biological aspects. Furthermore, it can be risky when life table data are used to build models to predict the demographic changes of the population. The present study highlights this aspect by comparing the impulse response generated by the raw data and by its Gaussian approximation based on the mean and the standard error. The conclusions of this paper highlight: i) the importance of adding more information to life tables and, ii) the role of raw data to ensure the completeness of this kind of studies. Given the importance of raw data, we also point out the need for further developments of a standard in the community for sharing and analysing data of life tables experiments.

Abstract
BACKGROUND Toumeyella parvicornis is an invasive soft scale insect native to North America that is rapidly spreading in Italy and France, provoking severe infestations on Pinus pinea L. To date, the control of this pest is entrusted to three endotherapic techniques whose short-term efficacy is partially known. No information on long-term efficacy is currently available, although fundamental. This work aims to report on the long-term effect that abamectin-based insecticides, injected with the three different techniques, have on adult female populations. RESULTS The study was carried out in an infested P. pinea forest in the area of Rome, Italy. Results showed that the tested methods had a similar long-term effect, and only in one case there were differences with the untreated control. Multiresidue analysis reported a zero level of abamectin in plant tissues 14 months apart from injection, except for one treatment where pesticide concentration was just above the limit of quantification. CONCLUSIONS This study represents the first long-term evaluation about endotherapic control strategy against T. parvicornis. In fact, the pest may quickly bring the death and fall of the stone pines, representing a concerning risk for citizens, however, control actions to manage it are still partially known and deserve more in-depth investigations. © 2023 The Authors.

Abstract
The pine tortoise scale, Toumeyella parvicornis, is an insect native to the Nearctic region that is able to infest several Pinus species. It can cause weakening, defoliation and, at high infestation levels, tree death. After its first report in Italy in 2015, the pest spread rapidly over the surrounding areas and was reported in France in 2021. Due to the threat that this pest poses to pine trees, the suitability of European Mediterranean basin areas for T. parvicornis at different spatial scales was estimated by constructing species distribution models (SDMs) using bioclimatic variables. Our results showed that several coastal areas of the Mediterranean basin area could be suitable for T. parvicornis. Based on performance assessment, all the SDMs tested provided a good representation of the suitability of European Mediterranean non-native area for T. parvicornis at different spatial scales. In particular, most of the areas with a medium or high level of suitability corresponded to the geographical range of distribution of different Pinus spp. in Europe. Predicting the suitability of European Mediterranean areas for T. parvicornis provides a fundamental tool for early detection and management of the spread of this pest in Europe.

Abstract
BackgroundThe management of patients with immuno-rheumatological diseases has profoundly changed during the COVID 19 pandemic and telemedicine has played an important role in the disease follow-up.In addition to monitoring disease activity and any adverse events, especially infectious events, assessing the psychological situation of the patient can be fundamental in particular considering that COVID-19 has also a serious impact on mental health and it has been demonstrated a significantly higher incidence of anxiety disorders and depressive symptoms especially in younger peopleObjectivesThe aim of this study is to evaluate the incidence of depressive disorders, anxiety and fibromyalgia in our patients with rheumatoid arthritis and psoriatic arthritis during the lockdown period due to the COVID 19 pandemic and validate the use of telemedicine in the clinical management of these patients.MethodsPatients affected by rheumatoid and psoriatic arthritis treated with biological disease-modifying drugs were contacted to evaluate the state of health and the presence of any adverse events and a nurse administered the clinimetric questionnaires assessment to evaluate the disease activity, the impact of rheumatic disease on the health status and the presence of anxiety, depression and fibromyalgia. In particular the following scales have been used: The Rheumatoid Arthritis Impact of Disease (RAID), the Psoriatic arthritis impact of disease (PsAID), Beck Depression Inventory BDI-II, State-Trait Anxiety Inventory (STAI) and The Fibromyalgia Rapid Screening Tool questionnaire (FIRST), The VAS scale for the assessment of pain. Patients who reported disease flare-up or adverse events underwent an outpatient visit and during visit Disease Activity Score (DAS 28) and Disease Activity Index for Psoriatic Arthritis (DAPSA) were used.Results171 patients with rheumatoid arthritis (RA) and 129 patients with psoriatic arthritis were enrolled. The incidence of fibromyalgia was increased in the two groups during the lockdown compared to the previous evaluations and in particular in patients with psoriatic arthritis (AR p =0.013, AP p= 0.001).Our analysis did not report significant differences between the two groups for the presence of fibromyalgia and anxiety-related disorders during lockdown, but a prevalence of depressive disorders in patients with rheumatoid arthritis was observed.During lockdown in RA patients, (n=50), no correlation was found between DAS28 and RAID score (r=0.112, p=0.438) and in PsA patients (n=34), no correlation was found between DAPSA and PSAID score (r=0.131, p=0.459) while median value of RAID was higher in STAI I and II positive and median value of PSAID was higher in STAI I and II positive. Patients positive at BDI had higher RAID score (median 6.28 vs 1.14) and PSAID (median 4.95 vs 2.85) score (Mann Whitney p<0.001 and p=0.003)ConclusionIn conclusion, mental and physical stress during COVID-19 pandemic can greatly worsen FM symptoms and intensify the patients’ suffering without a clinical flare of the inflammatory disease for patients affected by rheumatoid arthritis.Telemedicine has allowed us to identify patients who needed a face-to-face approach for therapeutic reevaluation even if not related to a flare of the disease.References[1]Coletto LA DermatolTher. 2020 Apr 14:e13415. doi: 10.1111/dth.13415.[2]Lurie N JAMA Intern Med 2018;178:745–6[3]Matteo Piga Seminars in Arthritis and Rheumatism 47 (2017) 121–128123Disclosure of InterestsNone declared

Abstract
BACKGROUND The pine tortoise scale, Toumeyella parvicornis (Cockerell, 1897), is a damaging insect pest native to North America. Its accidental introduction into Europe, where it was first reported in central-southern Italy, is leading to severe infestations among stone pine trees, Pinus pinea L. causing severe infestations and generating a major risk to the health and safety of the citizens as well. This preliminary study aimed at finding an effective low-impact control strategy against Toumeyella parvicornis. We evaluated the effect of endotherapic abamectin injected into infested stone pines in the Parco Archeologico di Ostia Antica (Rome). RESULTS Results showed that endotherapic abamectin significantly reduced the pine tortoise adult female populations and had a persistence into plants of approximately 60 days. The first trace of abamectin on the plant's crown was detected 1 month after the treatment. Moreover, the survey highlighted a higher presence of the pest on the twigs of the plants than on needles. CONCLUSIONS These findings offer an important tool in fighting the damaging activity of this phytophagous, especially in an urban context where interventions with treatments are strictly regulated by national laws. Endotherapy, in fact, would reduce the dispersion of active ingredients by drift, an aspect that could represent a valid alternative to manage plants in public areas. Given the actual lack of scientific information about other control solutions, abamectin endotherapic treatments would be the more effective strategy currently applicable. © 2022 The Authors.

Abstract
Biochar is a rich carbon product obtained by pyrolysis of biomass under a limited supply of oxygen. It is composed mainly of aromatic molecules, but its agronomic value is hard to evaluate and difficult to predict due to its great variable characteristics depending on the type of starting biomass and the conditions of pyrolysis. Anyway, it could be used as soil amendment because it increases the soil fertility of acidic soils, increases the agricultural productivity, and seems to provide protection against some foliar and soilborne diseases. In this study, the effects of biochar, obtained from olive pruning, have been evaluated on tomato seedlings growth and on their response to systemic agents' infection alone or added with beneficial microorganisms (Bacillus spp. and Trichoderma spp.). First, experimental data showed that biochar seems to promote the development of the tomato seedlings, especially at concentrations ranging from 1 to 20% (w/w with peat) without showing any antimicrobial effects on the beneficial soil bacteria at the tomato rhizosphere level and even improving their growth. Thus, those concentrations were used in growing tomato plants experimentally infected with tomato spotted wilt virus (TSWV) and potato spindle tuber viroid (PSTVd). The biochar effect was estimated by evaluating three parameters, namely, symptom expression, number of infected plants, and pathogen quantification, using RT-qPCR technique and −ΔΔCt analysis. Biochar at 10–15% and when added with Trichoderma spp. showed that it reduces the replication of PSTVd and the expression of symptoms even if it was not able to block the start of infection. The results obtained on TSWV-infected plants suggested that biochar could contribute to reducing both infection rate and virus replication. For systemic viral agents, such as PSTVd and TSWV, there are no curative control methods, and therefore, the use of prevention means, as can be assumed the use biochar, for example, in the nursery specialized in horticultural crops, can be of great help. These results can be an encouraging starting point to introduce complex biochar formulates among the sustainable managing strategies of plant systemic diseases.

Abstract
The Spotted Wing Drosophila (SWD), Drosophila suzukii (Matsumura), is a harmful insect pest for soft fruit cultivations. Even though its main hosts belong to the genera Prunus and Rubus, its high polyphagy and adaptability to new environments makes it a serious problem for farmers worldwide, who have reported several economic losses because of this pest. A wide series of proposals to control SWD are available and operate in line with the mechanisms of integrated pest management, demonstrating their high efficiency when applied at the opportune moment. This work aims to apply and validate a physiologically based model which summarises all the available information about D. suzukii biology, such as the relationship between environmental temperature and its development, fertility and mortality rates. The model provided, as a result, a description of a population of SWD females taking into consideration the multiple generations that occurred during the year. Simulations were then compared with field data collected in a three-year survey in two experimental fields located in the Sabina Romana area (Lazio, Italy). More specifically, D. suzukii males were monitored with traps in fields cultivated with mixed varieties of cherries and they were selected because of their clearer identification in comparison to females. Results showed a high level of reliability of simulations in representing the field data, highlighting at the same time that there is no discrepancy in simulating D. suzukii females in order to represent male populations.

Abstract
In summer 2016 a severe infestation of the alien ambrosia beetle Xylosandrus compactus was recorded from the Mediterranean maquis in the Circeo National Park in Central Italy. Trees and shrubs were infested and displayed wilting and necrosis of terminal branches caused by the combined impact of the insect and associated pathogenic fungi. A preliminary screening carried out on captured adults resulted in the isolation of a discrete number of fungal taxa with different life strategies, ranging from true mutualist (e.g. Ambrosiella xylebori) to plant pathogens (Fusarium spp.). In the present study, high-throughput sequencing was applied to determine the total diversity and functionality of the fungal community associated with X. compactus adults collected in the galleries of three Mediterranean woody hosts, Quercus ilex, Laurus nobilis, and Ceratonia siliqua. The effect of season and host in determining the composition of the associated fungal community was investigated. A total of 206 OTUs composed the fungal community associated with X. compactus. Eighteen OTUs were shared among the three hosts, including A. xylebori and members of the Fusarium solani complex. All but two were previously associated with beetles. Sixty-nine out of 206 OTUs were resolved to species level, identifying 60 different fungal species, 22 of which already reported in the literature as associated with beetles or other insects. Functional guild assigned most of the fungal species to saprotrophs and plant pathogens. Effects of seasonality and host on fungal community assemblage were highlighted suggesting the acquisition by the insect of new fungal taxa during the invasion process. The consequences of enriched fungal community on the risk of the insurgence of novel threatful insect-fungus association are discussed considering direct and indirect effects on the invaded habitat.

Abstract
Gonatopus duranprietoae sp. nov. (Hymenoptera: Dryinidae: Gonatopodinae) from Colombia is described and illustrated. This new species belongs to Gonatopus group 7. In this group, G. duranprietoae is similar to G. peruvianus Olmi, from Peru. The main difference between these two species is the shape of the metanotum: in G. duranprietoae lateral regions with two small pointed protrusions, which are absent in G. peruvianus. The key to the Neotropical species of Gonatopus group 7 is modified to include this new species.

Abstract
The diversity of the fungal community associated with adults of Dryocosmus kuriphilus following emergence was examined using HTS analysis. Ascomycota dominated the fungal core-biome community. The functional guilds of the 90 taxa forming the core-biome were assessed, demonstrating three main groups: saprotrophs, plant pathogens and entomopathogens. Twenty-nine OTUs out of 90 were resolved to species level identifying 26 different fungal species. Among these species, many were cosmopolitan or previously recorded in Europe. Ten taxa were previously recorded on chestnut, including some recognized plant pathogens associated with foliage and green tissues such as Epicoccum nigrum, Gnomoniopsis castanea, Colletotrichum acutatum, Stromatoseptoria castaneicola, Ramularia endophylla. Beauveria bassiana; within the core microbiome, Fusarium larvarum represented the most abundant entomopathogenic species. Some of these species are known to impact directly or indirectly the vitality of the insects in the galls. The chestnut blight pathogen, Cryphonectria parasitica, was never found associated with D. kuriphilus. Based on the present study, an active role for D. kuriphilus as a vector of chestnut fungal endophyte/pathogens cannot be demonstrated but neither ruled out.

Abstract
Purpose To evaluate the clinical characteristics and the visual prognosis of uveitis in juvenile rheumatoid arthritis (JRA). Methods The authors examined 63 patients with uveitis and JRA observed from January 1985 to December 2000. The following characteristics of each patient were considered: age at first visit, age at onset of uveitis and arthritis, sex, laterality and localization of uveitis, ocular complications, antinuclear antibody (ANA) and human leukocyte antigen (HLA) DR11 positivity, and follow-up. A retrospective study on mid-time visual outcome and ocular complications was performed on 42 patients with more than 12 months of follow-up. Results A total of 76.2% of the patients were female, with a mean age of 8.1 years. Chronic anterior uveitis was bilateral in 77.8% of the cases and unilateral in 22.2%. Arthritis was oligoarticular at onset in 87.3% of cases, and polyarticular in 12.7%. Mean age at arthritis onset was 4.5 years and mean age at uveitis onset was 5.4 years. ANA were positive in 92% of cases and HLA DR11 was present in 36 of the 43 patients tested (83.7%). Among the 42 patients with more than 12 months of follow-up, ocular complications occurred in 90.5% of cases and the most frequent were cataract (64.4% of eyes) and band keratopathy (59.2% of eyes). Secondary glaucoma (25% of eyes) was associated with the worst visual prognosis. A total of 64.5% of eyes maintained a visual acuity between 20/33 and 20/20 at the end of the follow-up. Conclusions Visual prognosis of uveitis associated with JRA is improving, owing to earlier diagnosis and intensive treatment. Ocular complications occurred frequently in patients with uveitis and JRA but they did not seem to seriously affect the final visual outcome. The authors did not observe any correlation between prognosis and sex, age at the onset of uveitis or arthritis, pattern of arthritis, or positivity for ANA or HLA DR11. In a percentage of cases, uveitis may develop before arthritis or years after the onset of arthritis; therefore, continuous ophthalmologic examinations are needed in young people with JRA.

Abstract
Gonadryinus bicarinatus Olmi, Marletta, Guglielmino & Speranza, sp. nov., from Ranomafana National Park (Fianarantsoa Province, Madagascar) is described and illustrated. This represents the first record of Gonadryinus from the Afrotropical region. The genus was previously known only from the Neotropical region, where only one species, G. hansoni Olmi, 1991, is recorded. The new taxon is different from G. hansoni because of the palpal formula 5/3 (4/2 in G. hansoni), the occipital carina complete (incomplete in G. hansoni) and two longitudinal keels present on the dorsal surface of the metapectal-propodeal complex (no longitudinal keels in G. hansoni).

Abstract
Gnomoniopsis castanea has been reported as the causal agent of necrosis of chestnut wasp (Dryocosmus kuriphilus) galls. The fungus is frequently observed on galls in chestnut stands infested by the insect in Italy. In the present study the impact of gall necrosis and the dynamic of its development have been studied in mature and young Castanea sativa stands in Central Italy during spring and early summer, before the D. kuriphilus adult flies. Results suggest that gall necrosis develops from resident endophytic inoculum of G. castanea. During the 2 y of monitoring, no differences were found in incidence and severity of the disease. Gall necrosis increased exponentially during the season, reaching 75,4% of galls totally necrotized in the investigated site in mid July. Gall necrosis was shown to have a severe impact on D. kuriphilus vitality, mostly impacting the adults inside the galls. Gall necrosis by G. castanea appears to efficiently control gall wasp in chestnut stands, although the high virulence of the fungus to chestnut fruits precludes its use as biocontrol agent in biological control strategies.

Abstract
A study on seasonal abundance of Auchenorrhyncha species and their infectivity by Xylella fastidiosa in the Apulia region of Italy was conducted to identify ideal periods for monitoring and adoption of potential control measures against insect vectors. Adult populations of Auchenorrhyncha species were monitored monthly over a 2-yr period from five olive groves. A total of 15 species were captured, identified, and tested for presence of X. fastidiosa by polymerase chain reaction (PCR). For three species, Philaenus spumarius L., Neophilaenus campestris (Fallèn), and Euscelis lineolatus Brullé, positive reactions to X. fastidiosa were obtained, on average, in 16.3, 15.9 and 18.4% of adult insects, respectively. Philaneous spumarius was the dominant species (39.8% of total Auchenorrhyncha captured) with the highest adult abundance in summer months. Adult P. spumarius and N. campestris were first detected between March and May in both years, and all insects tested during these periods (year 1: n = 42, year 2: n = 132) gave negative reactions to X. fastidiosa by PCR. Similarly, first adults of E. lineolatus that appeared from October to November (year 1: n = 20, year 2: n = 15) tested negative for presence of X. fastidiosa Given the lack of transstadial and transovarial transmission of X. fastidiosa and considering that P. spumarius is univoltine, control measures against nymphal stages of P. spumarius should be investigated as means of population suppression to reduce spread of X. fastidiosa in olive groves.

Abstract
A new species of Anteon Jurine, 1807 is described from Laos, Houaphanh Province: Anteonholzschuhisp. n. Morphologically the new species is similar to Anteonsemipolitum Olmi, 2008, but it is distinguished by the sculpture of the face partly reticulate rugose and partly with deep punctures similar to areolae; in Anteonsemipolitum the face is completely punctate and unsculptured among punctures. In addition, in the new species the distance from the outer edge of a lateral ocellus to the compound eye (OOL) is about 3.3 times as long as the distance between the inner edges of a lateral ocellus and the median ocellus (OL); in AnteonsemipolitumOOL is less than twice as long as OL. Published identification keys to the Oriental species of Anteon are modified to include the new species.

Abstract
Protosclerogibba australis Olmi, Marletta, Guglielmino & Speranza, gen. et sp. nov. is described and illustrated from specimens collected in Kimberley (Northern Cape Province, South Africa). The female of the new taxon is the first micropterous sclerogibbid. Females of other extant Sclerogibbidae are always apterous, whereas fossil females can be apterous or macropterous.

Abstract
The corn leafhopper Dalbulus maidis (Hemiptera: Cicadellidae), is an important corn pest in most of tropical and subtropical America. This leafhopper has a rich natural enemy complex of which parasitoids and pathogens are the most studied; knowledge on its predators is limited. We noted the presence of the native assassin bug Zelus obscuridorsis (Hemiptera: Reduviidae) predating diverse motile insects, including the corn leafhopper, on corn plants cultivated in household vegetable gardens in San Miguel de Tucumán (Argentina); in order to verify its predatory actions, we exposed lab-bred individuals of D. maidis to adults of Z. obscuridorsis. The predators were starved for 24 h before trials in which the corn leafhopper in different developmental stages were exposed. Zelus obscuridorsis is highly skilled in catching specimens in motion, but it was not able to prey on eggs. The predator was capable to catch and prey on nymphs and adults.

Abstract
BACKGROUND Sustainability is a broad and debated subject, often difficult to be defined and applied into real projects, especially when dealing with a complex scenario as the one of healthcare. Many research studies and evaluation systems have handled this topic from different perspectives, but many limits and criticalities still have to be overcome to properly cope with actual needs. METHODS The Sustainable Healthcare project has been developed through three main phases: a deep study of the state of the art, unraveling pros and cons of available sustainability scoring systems; an accurate analysis of the stakeholders network and their needs; the realization of an objective evaluation framework, through scientific methods, as the ANP. RESULTS The newly developed evaluation system takes into consideration all the three pillars of sustainability, analyzing social, environmental and economic sustainability through a set of criteria, specified by measurable indicators. So the system identifies both global sustainability and specific critical areas, pointing out possible strategic solutions to improve sustainability. The evaluation is achieved through technical analyses and qualitative surveys, which eventually allow to quantitatively assess sustainability, through a sound scoring method. CONCLUSIONS This study proposes an innovative evaluation method to determine the sustainability of a hospital, already existing or in the design phase, within the European context. The Sustainable Healthcare system overcomes some of the current evaluation systems' limits by establishing a multidisciplinary approach and being an easy-to-use tool. This protocol is intended to be of support in the identification of the main hospital's weaknesses and in setting priorities for implementation of the solutions.

Abstract
Two cases of a rare entity, spinal extrathecal hemangiolipoma, are presented. The clinical and histological features of the tumor are discussed, with particular attention to the uncommonly sudden onset of symptoms in one patient. Complete neurological recovery was exhibited by one patient after excision of the lesion, whereas only a partial recovery was achieved in the other case. The pathogenetic aspects of hemangiolipomas and the literature dealing with the previously reported 12 cases are reviewed.
