饲养温度对小菜蛾(Plutella xylostella)AchE和CarE活力的影响

CULTURE TEMPERATURE INFLUENCES ON THE ACTIVITIES OF ACETYLCHOLINESTERASE(ACHE) AND CARBOXYESTERASE(CARE) IN PIUTELLA XYLOSTELLA

在湿度定义为干、湿球温度差为3℃、光照强度10000-12000 lx、光照周期14L:10 D条件下,探索饲养温度(X:24-36℃)之变化对小菜蛾(Plutella xylostella)4龄幼虫乙酰胆碱酯酶(AchE)和羧酸酯酶(CarE)活力(Y)的影响效应。实验结果表明,活力指数随着饲养温度的升高而降低,两者之间存在显著的线性相关关系:温度与乙酰胆碱酯酶(AchE)活力两者间的相关关系函数式为Y=0．3327-0．0068X;与羧酸酯酶(CarE)活力的为Y=3．1278-0．0780X。

The indoor experiments were conducted to test the activities （Y） of acetylcholinesterase （Ache） and carboxyesterase（ Care ） in the 4th instar larvae of Plutella xylosteUa due to the constant culture temperatures （X： 24 -35 ℃ ）. Results led to estimate the equation for the relationship between the activities of AchE and cultural temperatures as Y = 0.3327 - 0.0068X, and that as Y = 3. 1278 -0.0780X for CarE.
