摘要
草地螟寄生蝇是草地螟Loxotego stictialisL.的重要天敌,但其发生种类、控害作用尚不明确。通过室内饲养,结合历年田间调查对康保县草地螟寄生蝇种类、田间分布、寄生率及消长规律进行研究,结果表明康保县草地螟寄生蝇发生种类有5种。田间呈聚集分布,种群数量大,寄生率高,控害作用显著。对开展草地螟预测预报,保护利用天敌资源和综合治理提供了科学依据。
Tachinid flies are important natural enemies of meadow moth, Loxotege stictialis L. But their species and control effect are still not clear. This paper studied the species, field distribution, parasitic rate and population fluctuation of tachinid flies on meadow moth in Kangbao by rearing in laboratory and investigating in field. The result showed that there were five species of tachinid flies on meadow moth in Kangbao. They presented aggregated distribution in the field with a large population and high parasitic rate. The control effect was significant. The results provides scientific bases for forecasting the population dynamics of meadow moth, protecting natural enemies, and developing integrated pest management.
