采用体外生物测定方法，测定了转Cry1Ab/Cry1Ac基因水稻上芝麻菜幼虫的摄食量、生长和存活情况。结果表明，取食Bt水稻的3龄和5龄幼虫的累积摄食率和相对摄食率均显著低于取食对照品种的幼虫。取食Bt水稻的3龄和5龄幼虫净生长均为负值。取食Bt水稻后，3龄幼虫的校正死亡率大多达到100%，5龄幼虫的校正死亡率为85%。
The food consumption, growth and survival of Sesamia inferens (Walker) larvae on cry1Ab/cry1Ac transformed rice were measured by in vitro bioassay. The results show that both the cumulative and relative food consumption rates of 3rd and 5th instar larvae feeding on Bt rice were significantly reduced compared to those of larvae fed on the control variety. The net growth of both 3rd and 5th instar larvae fed on Bt rice was negative. The corrected mortality of 3rd instar larvae mostly reached 100%, and that of 5th instar larvae 85%, with increased time after feeding on Bt rice.
