Bioassays with Bacillus thuringiensis var. galleriae Berliner δ‐endotoxin and plant phenolics on Heliothis armigera Hübner enhanced the activity of B.t. var. galleriae endotoxin. The presence of plant phenolics with B.t. var. galleriae endotoxin not only reduced feeding potential and weight gain by the larvae, but also enhanced the LC50 value of the toxin. Our study demonstrates the effect of phytochemicals from resistant crop plants on the biocidal activity of B. thuringiensis strains in laboratory conditions.
Reproductive strategies in relation to host diversity of a scelionid egg parasitoid, Trissolcus sp. on El4paleopada concinna Fab. and Homoeocerus prominulus (Tagus) are discussed, followed by the life table analysis of the parasitoid, indicating the preponderance of females due to solitary parasitism on the former host and a balanced sex ratio due to superparasitism on the latter.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
