摘　　要：为了探讨紫外线胁迫与棉铃虫体内乙酰胆碱酯酶(ACHE)及羧酸酯酶(CarE)活性之间的关系,分析比较了两种酶活性在紫外线照射不同时间(0min,30min,60min,90min)下的变化情况。结果表明:棉铃虫经过紫外线照射不同时间后,体内的AChE活性均有所降低,且在30min时达到显著水平;紫外线照射对棉铃虫体内的CarE活性有一定的抑制作用,紫外线30min、60min和90min CarE活性均显著低于对照。In order to reveal the relation between ultraviolet（UV）light stress and the activities of acetylcholinesterase（AChE） and carboxylesterase（CarE） in H.armigera adults,the effects of UV light irradiation on the activities of AChE and CarE were investigated in H.armigera adults.The adults were exposed to UV light for various time periods（0 min,30 min,60 min and 90 min）.AChE activity of adults exposed to UV light was reduced in comparison with the control adults,and a significant decrease was found at 30 min of exposure.CarE activity decreased in H.armigera adults following exposure to UV light for 30 min,60 min and 90 min in comparison with the control.
