Diversifying agroecosystems with floral habitats has the potential to conserve natural enemies and enhance pest control. In the laboratory, many adult parasitoids readily utilize nectar sources that have substantially increased their longevity and parasitism rates. However, in the field, does the floral habitat retain parasitoids locally so they exert greater control on pests? We studied the po...
There is a scarcity of studies concerning Plutella xylostella L. dealing with either interactions between partial plant resistance and insecticides or multitrophic interactions (with or without insecticides). Such studies are vital to allow improved understanding of possible interactions in IPM programmes and may help both to develop approaches which enhance cultural and biological controls and...
Since 1996, as part of a cooperative ARS/CIRAD Plutella biocontrol program, 115 Plutella populations have been collected in 32 countries from cole crops and cruciferous weeds. Twenty-seven primary hymenopterous parasitoid species were found, especially Diadegma spp., Cotesia plutellae and Oomyzus sokolowskii. A number of fungal pathogens, isolates of Paecilomyces fumosoroseus, Paecilomyces sp.,...
plant quality in herbivores’ diet may affect the performance of both herbivore and its parasitoids. in the present research, parasitism capacity of diadegma semiclausum (hellen) on plutella xylostella (l.) reared on different genetically manipulated brassica plants including the canola’s progenitor (brassica rapa l.), two cultivated canola cultivars (cultivar-opera and cultivar-rgs003), one hyb...
