Description
Summary:One concern about the use of transgenic plants is their potential risk to natural enemies. In this study, using the eggs of the rice brown planthopper,Nilaparvata lugens, as a food source, we investigated the effects of Cry1Ab rice on the biological characteristics and functional response of an important predatorCyrtorhinus lividipennis. The results showed that the survival ability (adult emergence rate and egg hatching rate), development (egg duration, nymphal developmental duration), adult fresh weight, adult longevity and fecundity ofC. lividipennis on Bt rice plants were not signiifcantly different compared to those on non-Bt rice plants. Furthermore, two important parameters of functional response (instantaneous search rate and handling time) were not signiifcantly affected by Bt rice. In conclusion, the tested Cry1Ab rice does not adversely impact the biological character and functional response ofC. lividipennis.
