Quackgrass, Elymus repens (L.) Gould, is a perennial grass spreading by vigorous underground rhizomes. Because of its capacity for rapid spread and persistence, it is considered as a common weed in many settings worldwide. The cereal rust mite, Abacarus hystrix (Nalepa), is a polyphagous, phytophagous mite attacking quackgrass and many other grasses including wheat. Its feeding causes leaf disc...

BACKGROUND Some studies reported the possible induction of food allergy, caused by neo-sensitization to cross-reacting allergens, during immunotherapy with aeroallergens, while other studies ruled out such possibility. OBJECTIVES The aim of this study was to evaluate the development of neo-sensitization to Pen a 1 (tropomyosin) as well as the appearance of reactions after ingestion of foods c...

PURPOSE To survey the species diversity of home dust mites (HDM) in Xishuangbanna, a tropical rainforest region in Southwest China. METHODS From August 2010 to January 2011, mite-allergic patients and healthy controls were invited to participate. Dust samples from the patients' homes were collected, and mites in the samples were isolated. Permanent slides were prepared for morphologically bas...

This study documents the interaction of two coccinellid-specific ectoparasites, a podapolipid mite Coccipolipus hippodamiae (McDaniel et Morrill) and a laboulbenialean fungus Hesperomyces virescens Thaxter with the lady beetle Harmonia axyridis (Pallas). The study objectives were to (1) determine the prevalence and intensity of both parasites and (2) predict the influence of parasitism on host ...

The pattern of inheritance of tracheal mite resistance in selected Russian bees was determined in bioassays and in samples from Þeld colonies. Resistant colonies of Russian origin and colonies selected for high susceptibility in the United States were used to generate divergent parental populations. Seven groups of F1 colonies were produced by crossing queens and drones from these selected resi...

Ten markers specific to Sarcoptes mites were used in applying microsatellite genotyping to individual Sarcoptes mites collected in three European countries from 15 wild mammal populations belonging to 10 host species. The results showed that geographical separation had real biological significance for the definition of mite sub-populations, and that the degree of genetic exchange occurring betw...

Spatial distribution studies in pest management identify the locations where pest attacks on crops are most severe, enabling us to understand and predict the movement of such pests. Studies on the spatial distribution of two mite species, however, are rather scarce. The mites Polyphagotarsonemus latus and Tetranychus bastosi are the major pests affecting physic nut plantations (Jatropha curcas)...

Two species of demodectic mites were described in the red deer Cervus elaphus, including Demodex kutzeri, which had also been found in other species of the Cervidae family in Austria, Germany, Czech Republic, Poland and North America. Whereas the other species, D. acutipes, had been previously known from only one finding in the Czech Republic. The present research included skin samples taken in...

Summary The efficacy and safety of subcutaneous immunotherapy with modified, high-dose, major allergen house dust mite extract is widely supported by double-blind, placebo-controlled studies. However, little is known regarding patient-perceived efficacy and satisfaction. An observational, retrospective, multicentre study in patients treated with Acaroid® was conducted to assess the efficacy and...

BACKGROUND In developed countries, it is estimated that 15% of the general population suffer from one or more allergic disorders, of which allergic rhinitis is the most common. Perennial rhinitis is most often due to allergy to the house dust mite. In such patients, house dust mite avoidance is logical, but there is considerable uncertainty regarding the efficacy and effectiveness of interventi...
