中文摘要:

调查结果发现，三叶斑潜蝇的寄生蜂主要有6 种，姬小蜂科Eulophidae 的底比斯釉姬小蜂Chysocharis pentheus(Walker)、冈崎灿姬小蜂Chysonotomyia okazakii (Kamijo)、丽灿姬小蜂Chysonotomyia formosa(Westwood)、黄潜蝇釉姬小蜂Chysocharis oscinidis Ashmead、异角亨姬小蜂Hemiptarenus varicornis (Girault) 和潜蝇科Agtomyzidae 的甘蓝潜蝇茧蜂Opius dimidiatus (Ashmead)，主要寄生三叶斑潜蝇二龄和三龄幼虫。4月、5月和11 月寄生蜂的发生数量占发生总量的68.23%，以5 月的寄生率最高，为40.03%；4 月次之为31.51%。其他月份其发生数量和寄生率较低。

英文摘要:

Six species parasitoids were found in L. trifolii, they were Chysocharis pentheus (Walker)，Chysonotomyia okazakii (Kamijo)，Chysonotomyia formosa (Westwood)，Chysocharis. oscinidis Ashmead，Hemiptarenus varicornis (Girault) and Opius dimidiatus (Ashmead).The parasitoids maily parasited the 2nd and 3rd larvae of L. trifolii. The parasitoids appeared in April, May and November and the highestparasitism was observed in May, which was 40.03%, and the parasitism in April and November was 31.51% and 11.16%, respectively.
