Intraguild predation (IGP) takes place when natural enemies that use similar resources attack each other. The impact of IGP on biological control can be significant if the survival of natural enemy species is disrupted. In the present study, we assessed whether Geocoris punctipes (Hemiptera: Lygaeidae) engages in IGP on Eretmocerus eremicus (Hymenoptera: Aphelinidae) while developing on whitefl...

Greenhouse whiteflies, Trialeurodes vaporariorum, are very small sucker-whipper-type pests of the family Aleyrodidae. They cause considerable damage to greenhouse crops in first order and show resistance chemical insecticides. In this context, we dedicated study control pest through active ingredients extracted from leaf fruit part pepper tree, Schinus molle by inhibiting chemosensory protein r...

The role of selective new generation bioisecticides, beside their effectiveness against key pests, relies on safety to beneficial arthropods. Spinetoram, a semi-synthetic analogue the microbial-derived bioinsecticide spinosad is registered worldwide for application in numerous crops, but assessment its ecotoxicological risk arthropods has scarcely been documented. Moreover, this first report to...

the side-effects of amitraz, buprofezin and propargite were studied on encarsia formosa (gahan)in the laboratory, using a life table response experiment and the iobc system for their toxicity. bioassayswere conducted by dipping bean leaves containing third instar nymphs of the whitefly trialeurodesvaporariorum (westwood), parasitized by e. formosa, in insecticide solutions or caging adult paras...
