Etoxazole, 2-(2,6-difluorophenyl-4-[4-(1,1-dimethylethyl)-2-ethoxy-phenyl]-4,5-dihydrooxazole, an organofluorine chitin synthesis inhibitor, was assayed for its bioactivities against several major insect and acarus pests and compared to several other pesticides: two chitin synthesis inhibitors, hexaflumuron and chlorfluazuron; a pyrethroid, permethrin; an organophosphate, acephate; a carboximid...

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 prey preference of polyphagous predators plays an important role in suppressing different species of pest insects. In this study the prey preference of the predatory mite, Amblyseius swirskii (Athias-Henriot) (Acari: Phytoseiidae) was examined between nymphs of the twospotted spider mite, Tetranychus urticae Koch (Acari: Tetranychidae) and first instar larvae of the western flower thrips, F...

Fourteen mite species of plant-associated mites of the suborder Prostigmata are reported from the Dominican Republic. Four of these refer to new findings for the country, including Petrobia (Tetranychina) hispaniola n. sp. Sánchez & Flechtmann, described from specimens collected from leaves of Citrus sp. (Rutaceae) and Rosa sp. (Rosaceae). A key for the separation of the world species of Petrob...

Three new species of myrmecophilous mites of the genus Scutacarus Gros, 1845 (Acariformes: Pygmephoroidea: Scutacaridae), S. lasiophilus sp. nov., S. myrmicinus sp. nov., and S. crinitus sp. nov. are described from ants and their nests in Tyumen Province, Western Siberia, Russia.

Eleven arboreal prostigmatic mites from the families Tydeidae, Iolinidae and Stigmaeidae (Prostigmata) are recorded from Hungary. Among them, 8 species are new for science: Tydeus narolicatus Kazmierski and Ripka sp. nov., T. martae Kazmierski sp. nov., T clavimaculatus Kazmierski sp. nov., Lorryia hungarica Laniecka and Ripka sp. nov., L. sanctikingai Ripka and Laniecka sp. nov., L. bathorii R...

Non-consumptive effects (NCEs) of predators are part of the complex interactions among insect natural enemies and prey. NCEs have been shown to significantly affect prey foraging and feeding. Leafhopper's (Auchenorrhyncha) lengthy phloem feeding bouts may play a role in pathogen transmission in vector species and also exposes them to predation risk. However, NCEs on leafhoppers have been scarce...
