Identification and eradication of murine fur mite infestations are ongoing challenges faced by many research institutions. Infestations with Myobia musculi and Myocoptes musculinus can lead to animal health problems and may impose unwanted research variables by affecting the immune and physiologic functions of mice. The purpose of this study was to evaluate the utility and efficacy of soiled be...

The spider mite, Eotetranychus smithi Pritchard & Baker (Acari: Tetranychidae), exhibits a facultative diapause that occurs at the egg stage. Diapause was induced by low temperatures alone (≤ 17.5°C) and averted by high temperatures (≥ 20°C). Photoperiod had little effect on diapause induction. This is the first example of temperature-induced diapause in spider mites. The diapause eggs became l...

• The non-linear DDE model is used to study honeybee-mite population dynamics with seasonality. Mites and age structure can destabilize that leads colony collapse. queen’s egg-laying rate has the greatest effect on size. Seasonality in either promote or suppress survival at different conditions. Honeybees play an important role production of many agricultural crops sustaining plant diversity un...

Fifty-four White Rock hens were infested with 2,000 northern fowl mites/ bird and six hens were sampled at nine time periods during the 28,week study. Hens supported an average of 15,028 mites when mites were collected from infested bird carcasses digested with a modification of the Cook's technique. Mite-specific Ilrccipitating antibodies were quantified from hen serum samples with rocket elec...

This study shows that out of 774 patients tested, the house dust mite (Dermatophagoides pteronyssinus) provoked the maximum response (51.81%) the house dust was second (42.81%), and shrimp was third (23.92%). The moderate allergenic extracts were cat fur (12.79%), dog fur (10.72%), cockroach (8.47%) egg white (7.56%) and orris powder (6.30%). Among the low allergenic extracts were Aspergillus f...

New distribution records and host associations of natural enemies banana insect mite pests are reported. These include eight parasitoids (two trichogrammatids, two mymarids, encyrtids, one pteromalid, scelionid) twelve predators (one thrips, staphylinids nine coccinellids). Two egg parasitoids, Prosoligosita perplexa Hayat & Husain Epoligosita duliniae Livingstone Yacoob reported for the fi...

Functional and numerical responses of the predatory mite, Neoseiulus longispinosus (Evans) (Acari: Phytoseiidae) to the red spider mite, Oligonychus coffeae Nietner (Acari: Tetranychidae), infesting tea were determined in a laboratory on leaf discs. Prey consumption increased with increases in temperature and prey density. Handling time decreased and successful attack rate increased with increa...

A microinjection technique has resulted in stable transformation of the western predatory mite Metaseiulus occidentalis. Early preblastoderm eggs within gravid females were microinjected. The needle was inserted through the cuticle of gravid females into the egg, or the tissue immediately surrounding the egg. This maternal injection method resulted in relatively high levels of survival and tran...

The two-spotted spider mite, Tetranychus urticae Koch, has caused significant damage to vineyards in the valley of São Francisco River Brazil. Neoseiulus idaeus Denmark & Muma is one most abundant species predatory mites on vines this region. This study evaluated population growth rates T. leaves two grape (Vitis vinifera L.) cultivars (‘Italia’ and ‘Superior Seedless’) jack bean [Canavalia ens...
