黄绿绿僵菌对烟草蚜虫的防治研究

Research on the Prevention and Control of Tobacco Aphid by Yellow Metarhizium

黄绿绿僵菌处理对烟草蚜虫AChE和GSTs活性的影响表现为:初期抑制作用不明显,随处理时间的延长出现显著的抑制作用。其最早出现抑制效应和达到最大抑制效应的时间为:AChE分别出现在处理后的32 h和40 h,GSTs则分别出现在处理后的48 h和56 h。黄绿绿僵菌处理后36 h,烟草蚜虫开始逐渐死亡。

After the invasion of yellow Metarhizium fkavoviride,the performance of activity of AChE and GSTs in tobacco a-phid showed:the inhibitory effect is not obvious at first,with the treatment time extending,the inhibition appeared.The first time that the inhibition effect and the time of maximum inhibition effect were:AChE appeared respectively at 32 h and 40 h after the treatment;The time of GSTs,respectively,was 48 h and 56 h after treatment.The tobacco aphid began to death at 36 h after invasion of Metarhizium.
