Table 1 Mortality and development time of Chrysoperla carnea larvae during the first two larval stages when fed exclusively with pollen from different Bt and non-Bt maize cultivars or with Ephestia kuehniella eggs (control treatment) (experiment 1). For statistical comparisons, logistic regression on mortality (egg hatching to moulting into L3) and ANOVA on development time (log transformed) of L1 and L2 were performed. Fixed factors were maize cultivar and trial. The model was full factorial. The control treatment was excluded from statistical analyses
