title: Effect of Bacillus thuringiensis naturally colonising Brassica campestris var. chinensis leaves on neonate larvae of Pieris brassicae.
abstract: The feeding of neonate larvae of Pieris brassicae (Order Lepidoptera) on leaves of brassica plants that had been colonised by Bacillus thuringiensis resulted in the death of 35% of the population within 72h. The bacteria multiplied in the cadavers, resulting in an increase of about 50-fold compared to the living insects. Surviving insects showed no ill effects during the time of the study. There was negligible multiplication of B. thuringiensis in the frass.
