Soil fauna drives crucial processes of energy and nutrient cycling in agricultural systems, influences the quality crops pest incidence. tillage is most influential manipulation soil structure, has a profound influence on biology its provision ecosystem services. The objective this study was to quantify through meta-analyses effects reducing intensity density diversity micro- mesofaunal communi...

A new genus and species of enarthronote oribatid mite, Psammochthonius kethleyi n.g., n. sp., is described and illustrated based on adult and immature specimens collected from coastal sandy soil in Thailand (Phangnga), Brazil (SAo Paulo) and the U.S.A. (Mississippi). Analysis shows that it is a member of Hypochthonioidea, but not of any named family, so the monobasic family Psammochthoniidae n....

As part of a research programme designed to identify biological agents for the control of sheep scab, the pathogenicity of the fungus Metarhizium anisopliae to Psoroptes mites in the presence of sheepskin and wool was examined in the laboratory. No inhibitory effects of skin and wool were observed and high levels of infection were recorded. Subsequently the pathogenicity of formulations of both...

Many mites were found on bookshelves near the windows in 2 rooms of the Department of Pediatrics on the 4th floor in the Tokai University Hospital. Fortunately, nobody reported being bitten by, or experiencing itching due to, the mites. The arthropods were tentatively identified as adults of the northern fowl mite, Ornithonyssus sylviarum (Canestrini et Frazago, 1877), commonly called "Torisash...

Background The house dust mites are cosmopolitan guest in human habitation. Dust mites occur in nearly all homes. They are generally found in pillows, bed sheets, mattress, stuff toys, carpets etc. Dust mites feed on organic detritus such as flakes of shed human skin and flourish in stable environment of dwellings. Exposure to house dust mites is recognized as major cause allergy worldwide. The...

Early researchers identified key concepts and developed tactics for multiple-option management of nematodes. Although the emphasis on integrated pest management over the past three decades has promoted strategies and tactics for nematode management, comprehensive studies on the related soil biology-ecology are relatively recent. Traditional management tactics include host resistance (where avai...

Methyl bromide, a highly toxic and ready penetrating fumigant, is widely used against rodents, insects, mites, and a range of pathogenic organisms in soil, compost, and timber. To disinfect soil in greenhouses, methyl bromide is brought under pressure from outside by a vaporiser and blown on to ground under a polyethylene cover. The gas being three times heavier than air easily penetrates the g...

Adult female twospotted spider mites, Tetranychus urticae Koch, reared on lima bean plants were moved to cucumber, maize, or new lima bean plants (the latter being a control) and evaluated after 24 h or 7 d for changes in susceptibility to three pesticides and in levels of related detoxification enzymes. The largest and most consistent changes were observed in mites feeding on cucumber. Suscept...

This study estimated the exposure to dust mites in various occupational environments in Croatia. In total, 29 occupational dust samples were collected: 10 from urban areas (offices, archive of an insurance company, tobacco, paper-recycling, fish-processing and textile plants, animal unit for experimental rats, winery), nine from rural areas (barley, hay, animal food and flour warehouses, tailor...

BACKGROUND Being exposed to house dust mites intensifies atopic dermatitis. This study has investigated the contamination rate with Dermatophagoides mites in patient's residential home with atopic dermatitis. METHODS In this cross-sectional study, 40 patients took part with atopic dermatitis (positive or negative for mites by prick Dermal Test). Samples were collected from 3 locations (living...
