三种本土赤眼蜂对番茄潜叶蛾卵的寄生能力比较
Comparison of Parasitism Ability of Three Indigenous Trichogramma Species to Tuta absoluta(Meyrick)Eggs
摘要
Abstract
Tomato leaf miner(TLM),Tuta absoluta(Meyrick),is a worldwide quarantine pest.Be-cause it has developed resistance to chemical pesticides,biological control methods should be needed for sus-tainable control.The aim of this study was to determine the parasitism potential of three indigenous Tri-chogramma species(T.chilonis,T.ostrinia,T.dendrolimi)on their natural host eggs of TLM,and to provide scientific bases for breeding good Trichogramma species and exploring their control potential to tomato leaf miner.The parasitic egg number,emergence rate and female ratio of the three Trichogramma species on TLM eggs within 24 hours were measured in laboratory.The results showed that T.chilonis and T.ostrinia had cer-tain parasitism effect on TLM eggs,and T.dendrolimi had no parasitism.The number of parasitic eggs of T.chilonis on TLM eggs was 16.93,and the number of parasitic eggs of T.ostrinia was 10.80.The offspring emer-gence rate of parasitic progeny was sequenced as T.chilonis＞T.ostrinia,and both were more than 70%with the female ratio more than 65%.In conclusion,T.chilonis and T.ostrinia could parasite TLM eggs,and T.chilonis was more suitable for controlling TLM and had broad application prospects.关键词
