【摘要】：【目的】了解褐飞虱对吡虫啉产生极高水平抗性后对其主要捕食性天敌黑肩绿盲蝽抗性发展的影响,为协调化学防治与生物防治的关系提供科学依据。【方法】分别用对吡虫啉敏感的褐飞虱种群(SN种群)和极高抗种群(RN种群)连续饲养黑肩绿盲蝽25代以及用吡虫啉对黑肩绿盲蝽连续诱导25代,每隔5代分别测定黑肩绿盲蝽的敏感性和酶活性。【结果】SNCF_(25)种群的敏感性变化不大;RNCF_(25)种群的LC_(50)值是原来的1.53倍;诱导(INCF_(25))种群LC_(50)值是原来的1.66倍。SNC、RNC和INC的黑肩绿盲蝽种群F_5、F_(10)、F_(15)、F_(20)、F_(25)代的酯酶和谷胱甘肽转移酶活性变化与抗性倍数的变化不一致,而多功能氧化酶活性变化与抗性倍数的变化较一致。【结论】黑肩绿盲蝽对吡虫啉的抗性发展较慢,其抗性发展与酯酶和谷胱甘肽转移酶的活性变化无关,与多功能氧化酶活性的变化成正相关。
[Abstract]:[objective] to investigate the effect of brown planthopper (BPH) on the development of resistance to imidacloprid and its main predatory natural enemy. To provide the scientific basis for coordinating the relationship between chemical control and biological control. [methods] 25 generations and pyramidine were continuously fed to brown planthopper population SN (sensitive to imidacloprid) and highly resistant population (RN) respectively. A continuous induction of 25 generations by phyline to the black shoulder and green bug. The sensitivity and enzyme activity were measured every 5 generations. [results] the sensitivity of SNCFSP 25) population was not much different from that of RNCFS 25) the LCSP 50) was 1.53 times higher than that of the original population. The LC50 value of the population was 1.66 times higher than that of the original population. The changes of esterase and glutathione transferase activity were not consistent with the change of resistance multiple. But the change of multifunctional oxidase activity was consistent with the change of resistance multiple. [conclusion] the resistance to imidacloprid was slow, and the resistance development was not related to the changes of esterase and glutathione transferase activity. There was a positive correlation with the activity of multifunctional oxidase.
