Studies of the dynamics changes in species composition pests fruit orchards context climate change became especially relevant. Monitoring phytophagous insects gardens with isolation dominant is a key component for building an effective system protection perennial plantings. The study was conducted 2018-2020 on basis Melitopol Experimental Station Horticulture named after M.F. Sidorenko IS NAAS....
House dust mites produce potent allergens that exacerbate asthma in sensitized patients, whom are recommended to practice allergen avoidance within their home environment. We tested the effect of activated charcoal impregnated fibers on house dust mite survival. One hundred live adult house dust mites (Dermatophagoides pteronyssinus) were added to eight culture dishes preequilibrated at room te...
The beneficial effects of oxygen are widely known, but the potentially harmful effects of high oxygenation concentrations in blood and tissues have been less widely discussed. Providing supplementary oxygen can increase oxygen delivery in hypoxaemic patients, thus supporting cell function and metabolism and limiting organ dysfunction, but, in patients who are not hypoxaemic, supplemental oxygen...
introduction mites of the phytoseiidae family have been extensively studied as biological control agents of different mites and insect pests. some species also feed on nematodes, fungal spores, pollen and exudates from plants and insects. about 2,300 phytoseiid species belonging to 90 genera have been described in this family (chant and mcmurtry 2007). considerable efforts have been made in rec...
during a faunistic survey of natural enemies of spider mites of genus tetranychus in mashhad and vicinity, a predatory gall midge species belonging to the family cecidomyiidae was collected and identified as feltiella acarisuga vallot. f. acarisuga is one of the ten species in the genus feltiella and an important biological control agent of tetranychid mites has previously been reported from va...
during the study on eriophyid mites associated to fabaceae plants in naghare village, lorestan province (iran), one new aculus species (acari: eriophyidae), a. lorestaniensis sp. nov. , was found on glycyrrhiza glabra l. and herein described and illustrated. this is the first aculus mites associated to a host plant of the genus glycyrrhiza .
In this overview of investigations into mite allergy in Iceland and of the current understanding of the sources of exposure, 2 major categories of mite-induced allergies were encountered. The first was house dust mite allergy due to house dust mites from unknown sources, and the second was barn allergy caused by mites connected with the degradation of stored hay. Characteristics of these diseas...
Non-diapausing spider mites (Tetranychus urticae) live on the undersurface of host leaves during summer, but diapausing mites overwinter in dark hibernacula. The light environments of these habitats differ: visible radiation (VIS) but not ultraviolet radiation (UV) reaches the undersurface of leaves, but neither enters dark hibernacula. Thus, mites of either seasonal form could locate their pre...
Cleaning symbioses represent classic models of mutualism, and some bee mites are thought to perform cleaning services for their hosts in exchange for suitable environments for reproduction and dispersal. These mutual benefits, however, have not been rigorously demonstrated. We tested the sanitary role of bee mites by correlating mite loads with fungal contamination in natural nests of Megalopta...
