Título em português: Bioensaios de alimentação induzida para determinar a atividade inseticidade Bacillus thuringiensis contra Epilachna paenulata (Coleoptera)  aThe objective ofthis work was to establish and test the induced-feeding bioassay in order to detect Bacil/us thuringiensis insecticidal activity against Epilachna paenulata (Coleoptera: Coccinellidae). Larvae were induced to swallow high concentrations of spore-crystal suspensions of seven exotic and 30 Argentine B. thuringiensis strains. The great majority of strains showed no toxicity to E. paenulata larvae, and observed mortality was lower than 30%. Induced-feeding bioassay is feasible, and should be used for prospecting strains that produce right combinations of Cry proteins needed to an efficient pest control.  aBiological control  aCoccinellidae  aCucurbitaceae  aLadybird beetle  aSpore-crystal toxicity1 aMONELLA, R.
