| 摘 要： | 本文利用花粉饲喂法研究了转cry1Ah基因玉米花粉对龟纹瓢虫Propylea japonica生长发育及成虫移动能力的影响。结果显示,与混有适量蚜虫的非转基因亲本对照玉米花粉(花粉与蚜虫重量比为2:1)相比,龟纹瓢虫幼虫取食混有适量蚜虫的转cry1Ah基因玉米花粉(花粉与蚜虫重量比为2:1)后,幼虫总发育历期、蛹期和成虫寿命均无显著差异,但1、3和4龄幼虫的发育历期显著高于对照,2龄幼虫的发育历期显著低于对照;2龄和4龄幼虫的存活率与对照无显著差异,但3龄幼虫的存活率显著增加;幼虫取食Bt花粉对该虫的蛹重、羽化率和雌雄比与对照无显著差异。幼虫期取食Bt玉米花粉而成虫期取食蚜虫对成虫的日产卵量无不利影响,与对照无显著差异。幼虫取食Bt玉米花粉羽化后雄虫和雌虫的步速和翻跃时间与对照均无显著差异。

| Abstract: | Laboratory feeding experiments were carried out to study effects of Bt corn pollen expressing cry1Ah toxin on the growth and development and adult mobility of Propylea japonica.Larvae of P.japonica were fed with transgenic cry1Ah corn pollen mixed with a certain proportion of the grain aphid Sitobion avenae,and non Bt corn pollen with a certain proportion of S.avenae,respectively.Parameters of growth,reproduction and adult mobility of P.japonica were assessed under laboratory condition.Results showed that d... |
