Assessing the Potential of Nano-Formulated Chlorfenapyr and Clothianidin Insecticides-Treated Sugar Baits against Anopheles funestus, Anopeles coluzzii and Culex quinquefasciatus Mosquitoes. Acta Trop 2024:107269. [PMID: 38821147 DOI: 10.1016/j.actatropica.2024.107269] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/28/2024] [Revised: 05/22/2024] [Accepted: 05/22/2024] [Indexed: 06/02/2024]
Abstract
Mosquitoes serve as vectors for various diseases like malaria, dengue fever, yellow fever, and lymphatic filarial diseases causing significant global health problems, highlighting the importance of vector control. The study was conducted to assess the effectiveness of nanoformulated clothianidin and chlorfenapyr insecticides treated with ATSB in controlling three mosquito strains. The development of a natural thiolated polymer-coated ATSB nano formulation involved incorporating nano-carriers to deliver insecticides. Field- collected mosquito strains were subjected to laboratory-based bioassays using 1% and 1.5% concentrations of each conventionally used and nanoformulated insecticide with ATSB solution. Adult mosquitoes were left overnight to contact with N-ATSB and efficacy was recorded after 36 and 72 h. The results showed that nanoformulated chlorfenapyr was significantly more effective as compared to clothianidin against An. funestus and Cx. quinquefasciatus but the results were not significantly different against An. coluzzii (100%). An. coluzzii was found to be the most susceptible strain followed by An. funestus and showed 100% and ∼ 98% mortality against nanoformulated chlorfenapyr (1.5%). Nanoformulated clothianidin induced more than 92% and ∼ 100% mortality against An. funestus and An. coluzzii respectively. However, Cx. quinquefasciatus significantly showed less mortality against nanoformulated clothianidin (88%) and chlorfenapyr (>95%) as compared to Anopheline strains. Furthermore, results indicate that nanoformulated insecticides significantly caused greater and prolonged fatality as compared to conventional form, suggesting effective and suitable strategies for vector management.

Abstract
Mosquitoes, as disease vectors causing global morbidity and mortality through diseases like malaria, dengue, and Zika, necessitate mosquito population control methods. This study investigated the efficacy of nano-formulated insecticide-based sugar baits in controlling Anopheles gambiae populations and assessed their potential non-target impact on Coccinella septempunctata. This laboratory-based study employed thiolated polymer-coated attractive toxic sugar bait (ATSB) nano-formulations, delivering pesticides via nano-carriers. Adult and larvae populations of insects were collected from rice and cotton fields subjected to bioassays with 0.5% and 1% concentrations of each nano-formulated and conventional insecticide within ATSB solution, alongside a control 100% attractive sugar bait (ASB). Mosquitoes interacted overnight with insecticide-treated baits, and mortality was assessed. Further observations up to 72 h were conducted for potential delayed toxic effects. Results highlighted nano-ATSB carbosulfan's effectiveness, particularly among organophosphates and pyrethroids. Among pyrethroids, nano-ATSB cypermethrin exhibited high efficacy, while Deltamethrin displayed lower mortality. Among organophosphates, nano-ATSB chlorpyrifos induced substantial mortality. The nano-formulations of insecticide were harmless against C. septempunctata compared to their conventional form. Nano-formulations demonstrated enhanced mortality rates and prolonged efficacy against mosquitoes, having a benign impact on non-target beetles. We expect these results to aid in developing effective plant protection products suitable for IPM practices.

Abstract
Due to its high polyphagy, Aphis gossypii is considered a key pest of many crops, and it can feed on hundreds of plant species belonging to the families Cucurbitaceae, Malvaceae, Solanaceae, Rutaceae, and Asteraceae. The control of this pest mainly relies on synthetic insecticides whose adverse effects on the environment and human health are encouraging researchers to explore innovative, alternative solutions. In this scenario, essential oils (EOs) could play a key role in the development of ecofriendly pesticides. In this study, the development of a citrus peel EO-based nano-formulation and its biological activity against A. gossypii both in the laboratory and field were described and evaluated. The phytotoxicity towards citrus plants was also assessed. The developed nano-insecticide highlighted good aphicidal activity both in the laboratory and field trials, even at moderate EO concentrations. However, the highest tested concentrations (4 and 6% of active ingredient) revealed phytotoxic effects on the photosynthetic apparatus; the side effects need to be carefully accounted for to successfully apply this control tool in field conditions.

Abstract
Abstract
Background
Insects withstand foreign substances and infection by expressing robust defense responses, which are mediated by hemocytes, fat body, midgut, and many other tissues. The Egyptian cotton leafworm, Spodoptera littoralis (Boisduval), is a polyphagous pest with considerable economic importance in Egypt and globally. Many control strategies were employed to control this pest. Nowadays, there is a trend to use nanotechnology tools in agricultural practices as they balance minimal concentration and maximum pest control, safe concentration, and reduce the cost of pest control. The present study aimed to evaluate the hematological and histopathological response of S. littoralis larvae post-treatment with sublethal concentrations of emamectin benzoate and its nanoform, besides the silver nanoparticles.
Results
The results revealed the high toxicity of emamectin benzoate and its nanoform (LC50 values were 0.0524 and 0.023 ppm, respectively). The results also showed that all tested compounds significantly influenced the mean number of laid eggs/female. The emamectin benzoate nanoform (837.3 ± 52.09) was the most efficient compound compared to the control (1999.3 ± 46.5). The hematological responses against the EMB + AgNP were lowered total hemocyte counting (22.41 ± 1.3) compared to the untreated larvae (38.08 ± 0.83). In addition, there were some histopathological changes in the midgut tissues. They were represented as destroying the integrity of the epithelial cells and the ciliated border. The columnar cells began to disintegrate, and the peritrophic membrane became vacuolized. In contrast, the cuticle layers were not affected by various treatments.
Conclusion
We can conclude that the employment of emamectin benzoate, either in its original form or as its nanoform, is considered a promising substitute for conventional insecticides. The nanoform of emamectin benzoate proved its high efficiency against the larvae of the cotton leafworm, which may allow the application of this formulation at low concentrations.

Abstract
A new systematic structural study was performed using the Atomic Force Microscopy (AFM) reporting statistical parameters of polymeric particles based on gelatin and poly-ε-caprolactone (PCL) containing essential oil from Lippia origanoides. The developed biocides are efficient alternative controlling agents of Conotrachelus humeropictus and Moniliophtora perniciosa, the main pests of Theobroma grandiflorum. Our results showed that the particles morphology can be successfully controlled by advanced stereometric parameters, pointing to an appropriate concentration of encapsulated essential oil according to the particle surface characteristics. For this reason, the absolute concentration of 1000 µg·mL-1 (P1000 system) was encapsulated, resulting in the most suitable surface microtexture, allowing a faster and more efficient essential oil release. Loaded particles presented zeta potential around (-54.3 ± 2.3) mV at pH = 8, and particle size distribution ranging from 113 to 442 nm. The hydrodynamic diameter of 90% of the particle population was found to be up to (405 ± 31) nm in the P1000 system. The essential oil release was evaluated up to 80 h, with maximum release concentrations of 63% and 95% for P500 and P1000, respectively. The best fit for the release profiles was obtained using the Korsmeyer-Peppas mathematical model. Loaded particles resulted in 100% mortality of C. humeropictus up to 48 h. The antifungal tests against M. perniciosa resulted in a minimum inhibitory concentration of 250 µg·mL-1, and the P1000 system produced growth inhibition up to 7 days. The developed system has potential as alternative controlling agent, due to its physical stability, particle surface microtexture, as well as pronounced bioactivity of the encapsulated essential oil.

Abstract
Considerable efforts have been spent on environmentally friendly particles for the encapsulation of essential oils. Polymeric particles were developed to encapsulate the essential oil from Piper nigrum based on gelatin and poly-ε-caprolactone (PCL) carriers. Gas Chromatography ((Flame Ionization Detection (GC/FID) and Mass Spectrometry (GC/MS)), Atomic Force Microscopy (AFM), Nanoparticle Tracking Analysis (NTA), Confocal Laser Scanning Microscopy (CLSM), Attenuated Total Reflectance-Fourier-transform Infrared Spectroscopy (ATR-FTIR), and Ultraviolet-Visible (UV-VIS) spectroscopy were used for the full colloidal system characterization. The essential oil was mainly composed of β-caryophyllene (~35%). The stability of the encapsulated systems was evaluated by Encapsulation Efficiency (EE%), electrical conductivity, turbidity, pH, and organoleptic properties (color and odor) after adding different preservatives. The mixture of phenoxyethanol/isotialzoni-3-one (PNE system) resulted in enhanced stability of approximately 120 and 210 days under constant handling and shelf-life tests, respectively. The developed polymeric system presented a similar controlled release in acidic, neutral, or basic pH, and the release curves suggested a pulsatile release mechanism due to a complexation of essential oil in the PCL matrix. Our results showed that the developed system has potential as an alternative stable product and as a controlling agent, due to the pronounced bioactivity of the encapsulated essential oil.

Abstract
With continuous development of pesticide dosage forms, emulsifiable concentrates using large amounts of organic solvents are gradually obsoleted. Nanoemulsions with high water content have been developed and the preparation processes also evolved, but these processes still exist some problems, such as poor controllability and high energy consumption. Microfluidic is a controllable nanoemulsion preparation system which mainly applied to pharmaceutical synthesis. In this study, the pesticide phoxim nanoemulsion was prepared by microfluidic technology. The optimized formulation of phoxim nanoemulsion was composed of Tween 80 and pesticide emulsifier 500 as surfactant, hexyl acetate as oil, and n-propanol as co-surfactant. Moreover, when the flow rates of water and oil in the microfluidic system were adjusted to 5 μL/min and 20 μL/min, phoxim nanoemulsion was obtained with a cloud point/boiling point of 109 °C, a particle size of 21.5 ± 0.8 nm and a potential value of - 18.7 ± 0.6 mV. Furthermore, the nanoemulsion had a rapid release effect in vitro which could be fitted by the Ritger-Peppas model. The feeding toxicity of the phoxim nanoemulsion was higher than that of commercial formulation while the contact killing effect was higher than that of the active ingredient. Therefore, pesticide dosage was reduced and the insecticidal effect was enhanced by using phoxim nanoemulsions. These results also confirm the potential of microfluidics as a green process to produce pesticide nanoemulsions.

Abstract
In this study, we utilized a hierarchical multilevel modeling approach to test the hypothesis that the activity of the organophosphate insecticide pirimiphos-methyl against the cosmopolitan serious secondary pest of stored products, the yellow mealworm, Tenebrio molitor (Coleoptera: Tenebrionidae), is affected by temperature, relative humidity (RH), and developmental stage (adults, small larvae, large larvae). Our results showed that as temperature increased from 20 to 25 °C, the observed mortality of T. molitor was significantly higher. Furthermore, mortality at 25 °C did not significantly differ from that of 30 °C. An ultimate increase at 35 °C resulted in the highest mortality rate of T. molitor. However, an increase of RH from 55 to 75% adversely affected the efficacy of pirimiphos-methyl. In our study, it is also shown that the insect developmental stage is a critical feature of pirimiphos-methyl efficacy. Tenebrio molitor adults exhibited significantly higher mortality than larvae. In addition, small larvae showed significantly higher mortality than large larvae. Thus, adult is the most susceptible developmental stage of T. molitor to pirimiphos-methyl treatment. Our results could be useful tools for the management of T. molitor by indicating the optimum combination of temperature and RH that favors the insecticidal treatment against this species. In addition, we expect that the percentage of developmental stages in a whole population of T. molitor affects the insecticidal efficacy of pirimiphos-methyl.

ENVIRONMENTAL SCIENCE AND POLLUTION RESEARCH INTERNATIONAL 2021; 28:7893-7900. [PMID: 33044698 DOI: 10.1007/s11356-020-11048-9] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/15/2020] [Accepted: 09/28/2020] [Indexed: 06/11/2023]
Abstract
Insecticidal treatment is a common practice for the control of stored-product insect pests. Most studies are focused on the direct effects of insecticides on target insects, while there are no data on the indirect effects on adults in terms of progeny fitness. This study deals with the effect of pirimiphos-methyl on adults of Tribolium castaneum (Coleoptera: Tenebrionidae), investigating their exposure time cost to progeny fitness. For this purpose, females of T. castaneum were exposed for 1, 3, 8, 16, 24, and 72 h to pirimiphos-methyl and progeny birth or death rates were calculated. The fecundity, as well as the survival of progeny, was affected by the parental exposure to the insecticide. When females were exposed for 1 and 3 h to pirimiphos-methyl, the net reproductive rate of the progeny was 4.1 and 4.3 females/female, respectively, which did not statistically differ with the progeny in control treatment (6.3 females/female). Further exposure time to pirimiphos-methyl affected significantly the progeny net reproductive rate, where the lowest value was observed at the 72-h exposure time (0.97 females/female). The intrinsic rate of increase, as well as the finite rate of increase, did not differ between the progeny of the control treatment (0.029 females/female/day and 1.029, respectively) and the progeny of exposed females at 1 h (0.021 females/female/day and 1.021, respectively) or 3 h (0.023 females/female/day and 1.023, respectively). By increasing the time of exposure to pirimiphos-methyl, a detrimental effect to progeny fitness was revealed based on the values of the intrinsic and finite rate of increase. The lowest values of these parameters were observed at the 72-h exposure time (0.001 females/female/day and 1.000, respectively). The same trend was observed in the values of the doubling time. In contrast, the mean generation time did not statistically differ between control and all insecticide treatments. The fact that the exposure of parental females of T. castaneum to pirimiphos-methyl negatively affects the demographic parameters of their offspring production should be seriously taken into account when management strategies are applied against this notorious stored-product insect species since it could reduce the repeatedly insecticidal applications in storage facilities.

Abstract
Ecotoxicological risk assessments of pesticides on non-target arthropods are often carried out under constant and optimal temperature regimes. However, living organisms rarely experience these conditions in real field situations. Understanding the impact of pesticides on non-target beneficial arthropods under temperature stresses is especially important in terms of global warming. We assessed the lethal and sublethal effects of four modern insecticides (chlorantraniliprole, cyantraniliprole, spinetoram, spinosad), on the generalist predator Macrolophus pygmaeus (Hemiptera: Miridae) under a range of temperatures (from 10 to 40°C) frequently experienced in a real field scenario. A reduction coefficient (Ex) was calculated by summarizing the mortality and predator reproductive capacity and, the chemicals were classified according to the International Organization for Biological Control (IOBC) toxicity classes. The insecticides showed a marked synergistic effect with temperature, as the predator mortality and reproductive outputs were significantly correlated with increasing temperatures. Spinosyns interacted significantly with temperature causing the highest mortality and lowest fertility rates. Anthranilic diamides showed a safer ecotoxicological profile compared to spinosyns, with cyantraniliprole being more harmful than chlorantraniliprole. These results suggest that temperature should be taken into account in pesticide ecotoxicology studies within the framework of integrated pest management and the recent climate changes.

Abstract
In this study, efficient and sensitive analytical methods based on liquid chromatography-tandem mass spectrometry were established to evaluate the degradation behavior of prothioconazole and prothioconazole-desthio along with mycotoxin contamination in wheat samples. The mean recoveries of prothioconazole and prothioconazole-desthio ranged from 76.05% to 96.17% with intraday relative standard deviations (RSDs) of 0.84%-14.38%. Mean recoveries of the five mycotoxins were 85.82%-103.24% with RSDs of 1.82%-7.03%. The residue and degradation behavior of prothioconazole was studied in wheat plant and grain under field conditions with different spraying equipment and prothioconazole formulations. Both application method and formulation affected prothioconazole degradation, and the content of all mycotoxin was lower than the national standards. The proposed analytic methods can be used to systematically evaluate prothioconazole and prothioconazole-desthio along with mycotoxin contamination in food. These results suggest that prothioconazole is safe for the control Fusarium head blight in wheat.

Abstract
Abamectin is a common biocide used to control agricultural insect pests. However, the water insolubility of abamectin may result in extra organic solvent introduced in the environment. To solve this issue, it is desirable to develop nanoformulations to encapsulate abamectin with environment-friendly polymers. In this study, two polylactic acid based abamectin nanoformulations were prepared. The average particle sizes, measured by dynamic light scattering and transmission electron microscope, were 240 nm and 150 nm, respectively. The insecticidal activity of these nano-formulated abamectin was examined in the laboratory on the pea aphid, Acyrthosiphon pisum (Hemiptera: Aphididae). The acute toxicity of nano-formulated abamectin on non-target aphid predator Adalia bipunctata (Coleoptera: Coccinellidae) was also evaluated by topical, residual and oral exposure. The two nano-formulated abamectin had comparable insecticidal effect with commercial abamectin formulation against the pea aphid. Taking median lethal concentration (LC50) as the toxicological endpoint, nanoformulations had higher contact toxicity and lower oral toxicity to first-instar larvae of the predator A. bipunctata. These results are expected to contribute to the application of solvent-free nano-formulated pesticides that comply with the integrated pest management (IPM) strategies.

Abstract
The use of conventional pesticides becomes a complicated issue as more species of insect pests become resistant to them. Nanopesticides suit new approaches in pest control. Herein, we tested the toxicological efficacy of imidacloprid compared with three of its nanoformulations (IMD01, IMD02, and IMD03) on second and fourth instar of Culex pipiens larvae. Furthermore, we assessed the synergistic actions of piperonyl butoxide (PBO) on imidacloprid and its nanoformulations against second and fourth instar of C. pipiens. The nanoformulation (IMD03) was the most potent insecticide (LC50 = 14, 6, and 2 ng/mL after 24, 48, and 72 h of exposure, respectively), whereas the lowest toxic nanoformulation was IMD01. However, imidacloprid had the lowest toxicity among the tested compounds (LC50 = 1015, 705, and 621 ng/mL after 24, 48, and 72 h of exposure, respectively). PBO significantly synergized imidacloprid and its nanoformulations. However, the most synergistic effects were on IMD03 and the lowest was imidacloprid itself. Based on our results, nanopesticides are currently the most promising tool to control C. pipiens mosquitoes. However, further semifield and field studies should be done to illustrate the efficacy of imidacloprid and its nanoformulations on C. pipiens mosquitoes.

Abstract
Plants are sources of numerous active substances that are used to protect crops. Currently, due to the limitations of using synthetic insecticides, plant products have attracted increasing attention as possible pesticides. In this review, we discuss some of the most interesting plant products (for example, Solanaceae, or Asteraceae extracts, Artemisia absinthium or Citrus spp. essential oils, and single compounds like α-chaconine, or α-solanine) that exhibit insecticidal activity against beetles that are pests of stored food products. Next, we describe and discuss the mode of action of these products, including lethal and sublethal effects, such as antifeedant or neurotoxic activity, ultrastructural malformation, and effects on prooxidant/antioxidant balance. Furthermore, the methods of application of plant-derived substances in food storage areas are presented.
