摘要: 在农林业生产中,化学农药的使用成为了生物防治实施的制约因素之一。为了促进化学防治和生物防治的协调应用,评估农药对天敌昆虫的影响是天敌昆虫推广应用中的重要环节。异色瓢虫Harmoniaaxyridis是我国农业生产中常用的捕食性天敌之一,为了确保异色瓢虫在应用中的安全性,保障其持续发挥控害作用,本文采用毒蚜饲喂法,以卵巢发育情况为指标,评价了常用杀菌剂代森锰锌对异色瓢虫雌成虫的生殖毒性。试验结果表明,不同发育阶段的异色瓢虫在摄入代森锰锌后均会出现雌成虫卵巢发育受抑制的现象。主要表现为卵巢管长度下降、卵巢发育指数降低、Vg1Vg2相对表达量降低。并且摄入代森锰锌的时间越长,对卵巢发育的抑制作用也越明显。此外,通过解剖观察未发现代森锰锌对异色瓢虫卵巢具有致畸作用。因此,推测代森锰锌对异色瓢虫具有较弱的生殖抑制作用。本文研究结果将增强代森锰锌与捕食性天敌昆虫应用的兼容性,提高代森锰锌与天敌昆虫的使用效率。

Abstract: In agricultural and forestry production,chemical pesticides have become one of the constraints against biological control.To coordinate chemical control with biological control,it is important to evaluate the effects of pesticides on natural enemy insects.Harmonia axyridis is one of the widespread predators widely used in agricultural production in China.To ensure the safety and the continuous control effect of H.axyridis during its application,this paper evaluated the reproductive toxicity of mancozeb to H.axyridis female adults by aphid feeding method.The ovary development degree and the relative expression of Vgs were investigated in the female predators fed with mancozeb.The results showed that the ovarian development was inhibited in the H.axyridis female adults,irrespective of the developmental stages when mancozeb was ingested.The main symptoms included decreases in follicle length,ovarian development index and the relative expression of Vg1 and Vg2.Consuming mancozeb since the larvae stage was more detrimental to the ovarian development compared to consuming since the adult stage.However,mancozeb treatment resulted in no abnormal ovary.Therefore,mancozeb probably has a weak reproductive toxicity effect on H.axyridis.The results can help improve the compatibility of mancozeb and predator and the efficiency of application of mancozeb and predator.
