摘要: 为明确氯虫苯甲酰胺亚致死浓度对玉米螟赤眼蜂寄生及繁殖能力的影响,本研究利用HollingⅡ功能反应模型分析了氯虫苯甲酰胺作用下玉米螟赤眼蜂对米蛾卵的寄生功能反应特征;同时,通过数值反应参数描述了氯虫苯甲酰胺作用下玉米螟赤眼蜂的种群数量变化情况。研究结果表明:经氯虫苯甲酰胺处理后的玉米螟赤眼蜂对米蛾卵的功能反应类型虽基本符合HollingⅡ模型,但模型的各项参数有所改变。在氯虫苯甲酰胺的作用下,玉米螟赤眼蜂对米蛾卵的瞬间攻击率增强,处置时间延长,寄生效能由60.46降低至56.05,寄生上限也由57.21粒下降至44.24粒,且搜寻效应也随着米蛾卵密度的增加而逐渐降低。当米蛾卵密度大于10粒时,氯虫苯甲酰胺对玉米螟赤眼蜂种群干扰作用控制指数的影响随着米蛾卵密度的增加而减弱,米蛾卵密度10粒为维持玉米螟赤眼蜂种群繁衍的临界值。综上所述,氯虫苯甲酰胺对玉米螟赤眼蜂寄生能力,生长发育及繁殖均存在一定程度的负面影响,这为害虫治理过程中科学协调化学防治和生物防治,以及为指导科学用药提供理论基础。

Abstract: This study aims to clarify the effects of sub-lethal concentration of chlorantraniliprole on parasitizing and reproductive ability in Trichogramma ostriniae. The characteristics of the parasitic functional response of T. ostriniae to Corcyra cephalonica (Stainton) eggs under the treatment of chlorantraniliprole were analyzed by HollingⅡ functional response model. Meanwhile, the density changes of T. ostriniae under the treatment of chlorantraniliprole were described using numerical response parameters. The results showed that the functional response fitted with HollingⅡ model and that the model parameters varied after chlorantraniliprole treatment. The successful attack rate was enhanced, and the prey handling time was extended, parasitizing efficiency was reduced from 60.46 to 56.05 and maximum parasitizing capacity was reduced from 57.21 to 44.24 eggs. The searching efficiency decreased with the increase of C. cephalonica egg density. When the density of C. cephalonica eggs was greater than 10, the influence of chlorantraniliprole on the interference of T. ostriniae weakened with the increase of C. cephalonica egg density. A density of 10 C. cephalonica eggs was the critical value for maintaining the reproduction of T. ostriniae population. In conclusion, chlorantraniliprole has a certain degree of negative impact on the parasitizing capacity, growth and development, and reproductive capacity of T. ostriniae. The results are helpful for rational and scientific use of pesticides and for coordination of chemical and biological control.
