Integrated pest management (IPM) tactics may effectively control focal pests, but it is also important to test the compatibility of different tactics, and consider non-target organisms. We investigated the effects of a neonicotinoid seed treatment and Rag resistance genes used for soybean aphid (Aphis glycines Matsumura) control on reproduction of a non-target herbivore (twospotted spider mite,...

although host plant resistance is the healthiest, most reliable and cheapest way of pest control, to achieve a successful integrated pest management, pest-resistant plant varieties should be compatibity with the biological control agents. throughout the present study, the performance of the predatory mite, phytoseiulus persimilis، on four common bean cultivars (naz, khomein, akhtar and g11867) ...

the grape erineum mite (gem), colomerus vitis (pagenstecher) (acari: eriophyidae) is considered to be one of the most important pests, that sometimes causes irreversible damages to grapevine cultivars in western parts of iran. studies were carried out in order to find natural enemies associated with gem, during 2011-2013. results indicated that natural enemies included two species of predatory ...

Climate warming can destabilize interactions between competitors as smaller organisms gain advantages in warmer environments. Whether and how warming-induced effects on competitive interactions are modified by predation remains unknown. We hypothesized that predation will offset the competitive advantage of smaller prey species in warmer environments because of their greater vulnerability to pr...

The cultivation of tropical fruit trees has grown considerably in the state of Bahia, northeastern Brazil. Some of these have been severely attacked by phytophagous mites, which are usually controlled by the use of chemical pesticides. However, there is today a growing interest for the adoption of less aggressive measures of pest control, as for example the use of predatory mites. Most of the p...

We recorded three mite species, Pergamasus (Thenargamasus) instatutus Athias-Henriot, 1967, (Pergamasus) laminarius Witaliński, 1971 and Holoparasitus ampullaris 1994, from Slovakia for the first time. Mites of genera Berlese, 1903 Oudemans, 1936 are predatory mites living mainly in a soil rotting organic matter Holarctic region with centre distribution Europe. Till now, P. was Austria Hungary,...

in iran, cheyletid mites (acariformes: cheyletidae) were collected over 15 years (1996–2010) in stored cereal. samples were collected from silos, flour-mills, barn and rice-mills in 12 provinces scattered throughout the north,  centre, east and west of iran. 8 genera and 13 species were recorded: acaropsellina sollers (kuzin, 1940), cheletomorpha lepidopterorum (show, 1794), cheyletus bidentatu...
