摘要
用100×10-6%农梦特和空白农梦特乳油,以及0.01×1O-6%氯氰菊酯处理寄生于小菜蛾幼虫的优姬蜂雄蜂,观察农药亚致死剂量对优姬蜂交配行为的影响。结果表明,受农梦特处理的雄蜂只有68.18%在遇到雌蜂时引起翅膀扇动。在农梦特和氯氰菊酯处理中,雄蜂对雌蜂在交配行为上的反应迟钝,它们从试验开始到扇动翅膀的时间显著地比对照和空白农梦特乳油的推迟,其交配率分别为27.27%和55%,交配抑制率分别为53.68%和32.06%。
Sublethal doses of insecticides,100×10-6% of Nomolt,blank Nomolt and 0.01×10-6% of Cypermethrin were used to treat adult male parasitoid Diadegmaeucerophaga in Plutella xylostella and evaluate the sublethal effects of the inse-cticides on the mating behaviour of male wasps evaluate.The results showedthat there were 68.18% of males fanning their wings in the Nomolt treatment,while 100%,100% and 95% of males fanning their wings in the control,blank Nomolt and Cypermethrin,grovbs respectively.And the time the malewasps started to fan their wings from the beginning of experiment in theNomolt and Cypermethrin treatmeat was significantly less than that in the controlIt revealed that the mating rates of male wasps in Nomolt and Cypermethrintreatment were 27.27 % and 55 % respectively,which were all lower than inthe control(80.95 %).Mating suppression(MS)was used to analyse the effectof male wasps mating. The MS rates in the treatment of Nomolt andCypermethrin were 53.68 % and 32.06 % respectively.
