Abstract
Crude ethanol extracts (CE) of leaves of 60 plant species belonging to 32 families and 52 genera were bioassayed for toxicity to adult Tribolium confusum by spraying a 10% (w/v) concentrate under a Potter's tower. CE of 8 plants had none and 3 had some bioactivity; 36 CE killed from 13% to 40% of the beetles. Thirteen plant extracts inflicted between 53% and 100% mortality in the following order: Azadirachta indica(53%) < Eupatorium odorantum=Gliricida sepium=Mimosa pudica (60%) < Annona reticulata=Hibiscus rosa sinensis(67%) < Cycloptis semicordata < Artocarpus altilis < Capsicum annum (90-97%) < Bontia daphnoides=Cuscuta americana=Dioscorea polygonoides=Nicotina tabacum (100%).....
