Impact of feeding purified Cry3Bb1, Cry1Ab and GNA on life-table parameters of adult <i>Chrysoperla carnea</i>.

Pairs of C. carnea were fed an artificial diet containing 150 µg Cry3Bb1, 120 µg Cry1Ab or 9 mg GNA (positive control) per g dry weight of artificial diet. Pure diet served as a negative control. The experiment lasted for 28 days. Statistical comparisons were made for each of the insecticidal proteins with the control. Asterisks denote significant differences: *P<0.05, **P<0.01; aExperiment started with n = 36 per treatment. Pairs producing no or only infertile eggs removed from analyses; bChi-square test; cMann-Whitney U-test; dDunnett test.
