Control of the straw itch mite (Acari: Pyemotidae) with sulfur in an insect rearing facility.

Pyemotes herfsi (Acari: Pyemotidae), a mite new to North America as the cause of bite outbreaks.

High incidences of red, itching, and painful welts on people in the midwestern United States led to the discovery of a European species of mite, Pyemotes herfsi (Oudemans) (Acari: Pyemotidae), preying on gall-making midge larvae on oak leaves. The mites' great reproductive potential, small size, and high capacity for dispersal by wind make them difficult to control or avoid.

Uiosystematics of the straw itch mite with special reference to nomenclature and dermatology

I. Cross-mating of various populations of Pycvnotcs obtained from laboratory insect cultures demonstrated that the strawitch mite is a single, widely dispersed species, different from P.z~cntricoszts, which was probably associated with the furniture beetle. 2. P.ventricoszcs should not be the approved scientific name for the straw itch mite. The correct name for the straw itch mite is Pj?en~otc...

An Evaluation of the Straw Itch Mite, Pyemotes Tritici, for Control of the Red Imported Fire Ant

Infestation by Pyemotes tritici (Acari, Pyemotidae) causes death of stingless bee colonies (Hymenoptera: Meliponina).

We report the infestation of stingless bee nests by the mite Pyemotes tritici, which killed four colonies of Tetragonisca angustula and one colony of Frieseomelitta varia in Brazil. The first infected colony, a colony of T. angustula, came from an area between Uberlândia and Araguari, Minas Gerais. The transfer of the mites to the other colonies occurred through the transfer of infected combs a...

Effects of powdery mildew fungicide programs on twospotted spider mite (Acari: Tetranychidae), hop aphid (Hemiptera: Aphididae), and their natural enemies in hop yards.

Twospotted spider mite, Tetranychus urticae Koch (Acari: Tetranychidae), and hop aphid, Phorodon humuli (Schrank) (Hemiptera: Aphididae), are the most important arthropod pests of hop (Humulus lupulus L.) in the Northern Hemisphere. A potential barrier for greater adoption of conservation biological control strategies for spider mites and hop aphid is the extensive use of fungicides for managem...
