[Morphological observation on hypopus of Lepidoglyphus destructor by optical microscope]

Objective To observe the external morphology of Lepidoglyphus destructor hypopus under an optical microscope. Methods The samples were collected in a store of Chinese medicinal herbs in Huainan City in September, 2016, the L. destructor and the hypopus were isolated, and then made of slide specimens. The slide samples were prepared and observed under an optical microscope. Results The L. destructor hypopus and protonymph were found. The inactive hypopus was oval in shape, the feet were not welldeveloped, there was a distinct transverse seam on its back, and there were 2 pairs of genital sensory organs. Conclusion The optical microscopy shows the morphological characteristics of L. destructor hypopus, which can provide the basis for the biological classification and the prevention.

[Gohieria fuscus breeding heavily in grand dust flour of a flourmill]

Objective To investigate the breeding quantity and average breeding density of Gohieria fuscus in the grand dust flour of a flourmill and explore the prevention and control measures. Methods A certain amount of grand dust flour was collected from a flourmill, and it was sieved. The powder was placed into the glass pan, and the mites were sought out under an optical microscope and made of specimens. The mites were identified on the basis of literature. Results In this survey, 400 g samples were collected from 4 habitats. The average breeding density of mites was 3 516/g. The mite was identified as Gohieria fuscus. ConclusionsGohieria fuscus is one of the widely distributed stored mites. It impacts the stored food and reduces the quality of food. In addition, the mite affects human health. Therefore, the preventive measures should be taken.

HOLON/CADSE: integrating open software standards and formal methods to generate guideline-based decision support agents

This paper describes the efforts of a consortium that is trying to develop and validate formal methods and a meta-environment for authoring, checking, and maintaining a large repository of machine executable practice guidelines. The goal is to integrate and extend a number of open software standards so that guidelines in the meta-environment become a resource that any vendor can plug their applications into and run in their proprietary environment provided they conform to the interface standards.
