摘要: 为了系统地了解不同作用机制杀虫剂对绿盲蝽毒力的温度效应。本文采用食料浸渍法,测定了15、20、25、30、35℃下,8种杀虫剂对绿盲蝽3龄若虫的室内毒力,并结合前期研究结果进行了综合分析。测定结果表明,乙酰胆碱受体激活剂吡虫啉和啶虫脒、几丁质合成抑制剂氟铃脲、氯离子通道激活剂阿维菌素和氯离子通道抑制剂氟虫腈对试虫表现为强正温度效应。温度对钠离子通道调控剂影响较复杂,高效氯氰菊酯为强负温度效应,氰戊菊酯基本不受温度影响,高效氯氟氰菊酯则具有弱负温度效应。乙酰胆碱酯酶抑制剂等其他杀虫剂均受温度影响较小。研究结果说明,除钠离子通道调控剂对绿盲蝽毒力的温度效应较复杂外,其他杀虫剂温度效应均有较强规律性。

Abstract: To systematically understand the temperature effect of different kinds of insecticides with different mechanisms to Apolygus lucorum, the toxicities of eight kinds of insecticides to the third instar nymphs of A. lucorum were measured at 15, 20, 25, 30 and 35℃ by food-dipping method. And a comprehensive analysis was conducted using the results combined with the previous study. The results showed that acetylcholine receptor activator (imidacloprid and acetamiprid), chitin synthesis inhibitor (hexaflumuron), chloride ion channel activator (avermectin) and chloride ion channel inhibitor (fipronil) showed a strong positive temperature effect. The temperature effects of sodium channel control agents were relative complexed. β-cypermethrin showed a strong negative temperature effect, fenvalerate was not affected by temperature and λ-cyhalothrin showed a weak negative temperature effect. Temperature did not have effect on other pesticides. The results showed that except the sodium channel control agents which have complex temperature effects, temperature effects of other insecticides all showed strong regularity according to their mechanisms.
