东亚小花蝽成虫对番茄潜叶蛾卵的捕食能力
Predatory Capability of Orius sauteri Adults on Eggs of Tomato Leaf Miner(Tuta absoluta)
摘要
Abstract
Tomato leaf miner(Tuta absoluta)is an important worldwide quarantine pest.It invaded Xin-jiang in 2017 and rapidly spreads to many provinces in China,seriously threatening the development of China's tomato industry.In order to evaluate the predatory capability and control potential of Orius sauteri,a mature and commercial natural enemy insect,on tomato leaf miner,the feeding situation,predation function response and search effect of O.sauteri on tomato leaf miner eggs were studied in laboratory.The results showed that O.sauteri had better predation ability on tomato leaf miner eggs,and its predation function response conformed to the Holling Ⅱequation model.The daily predation amount increased with the increase of prey density.The fe-male adult of O.sauteri had stronger predation ability(a′/Th)for tomato leaf miner eggs compared to the male adult,with the maximum theoretical predation limit as 64.102 4 eggs.The search effect decreased with the in-crease of prey density,and that of female adults was higher than that of male adults.In conclusion,O.sauteri had great biological control potential against the invasive pest tomato leaf miner.关键词
