it has been hypothesized that the survival, development, fecundity and population of insects are affected significantly by high temperatures. the diamondback moth, plutella xylostell (l.) (lepidoptera: plutellidae), is a serious and economically important pest of cruciferous crops throughout the word. in this research, the adult longevity and fecundity of p. xylostella were studied in laborator...

the diamondback moth, plutella xylostella (l.) (lep.: plutellidae) is one of the most destructive insectpests of cruciferous crops throughout the world. in this research, the demographic parameters of p. xylostellawere studied on five rapeseed cultivars including licord, modena, okapi, rgsoo3 and regxkobra. theexperiments were conducted in a growth chamber at temperature of 25 â± 1â°c, 60 â± 5%...

Levels, genetic traits and stability of resistance to Bacillus thuringiensis of the Bang Bua Tong (BS) population of the diamondback moth Plutella xylostella collected in Thailand were investigated. The BS population exhibited 668 and 66.5-fold resistance to formulations derived from B. thuringiensis subsp. kurstaki (Toarow CT®), and B. thuringiensis subsp. aizawai (XenTari®), respectively. In ...

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...

In order to identify genotypes resistant pest, cabbage accessions VIR global collection were assessed field according plant infestation and damage by diamondback vicinity St. Petersburg. Materials methods . The was on model when ex...
