Effects of Artemisia annua L.(Asteracea) on nutritional physiology and enzyme activities of elm leaf beetle, Xanthogaleruca luteola Mull.(Coleoptera: Chrysomellidae)
Methanolic extract of Artemisia annua L., a weed collected around paddy fields in north of
Iran, was investigated for its toxic effects on: feeding, growth, fecundity, fertility including the
biochemical characteristics of elm leaf beetle Xanthogaleruca luteola Mull. The toxicity tests
indicate that insecticidal effect was 2.4-fold higher in 3rd instar larvae than in adults. The
LC50 was 48% and 43.77% of a methanolic leaf extract at 24 and 48h, respectively. The
feeding deterrence was highest at 10% concentration and lowest at 0.625% for 3rd instar …
