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

چکیده
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~otcs tritici. 3 . Various Pye.motes species differ in preferred habitats, hosts, and toxicity to man. Whereas P.tritici comrnoniy attacks grain insects and is highly toxic to man, other species attack wood boring insects and may cause little or no irritation. P.scolyti and P.par~iscalyti , which attacli bark beetles, cause no observable symptoms. 4. It is suggested that before Pyemotes are used as biological control agents against bark beetles, it is important to identify the species correctly.

Application of dusting sulfur to logs that contained pupating borers greatly reduced densities of mites on emerging adult beetles and increased beetle survivorship. Uniform ...

never demonstrated.1 The itch (in French "la gale") is a disease characterized by violent itching, pimples and scabs on the skin. Today it is accepted that the itching is due to an insect, the sarcoptes, burrowing tunnels into the dermis in order to deposit its eggs, cutting through both the dermis and the small vessels in its path. The tissue reacts, creating small vesicles filled with a serou...
