摘要

摘要/ Abstract摘要:研究了美国蒙大拿州和北达科他州小麦茎锯蝇(Cephus cintus Norton，膜翅目:小蜂科)晚季幼虫被当地小蜂(bron F.，膜翅目:小蜂科)寄生的8年时间。我们发现，在75%的研究地点和年份中，滞育室中幼虫的寄生率最高可达46%，超过了先前报道的最高2.5%。与之前的研究相反，我们的研究结果表明，即使在滞育室形成之后，c.c inctus幼虫也是bronid寄生蜂的合适寄主，并且表明如果在收获前取样茎，则寄生率可能被低估。

Unexpectedly High Levels of Parasitism of Wheat Stem Sawfly Larvae in Postcutting Diapause Chambers

Abstract We examined rates of late-season parasitism of larvae of the wheat stem sawfly, Cephus cinctus Norton (Hymenoptera: Cephidae), by native species of Bracon F. (Hymenoptera: Braconidae) over 8 years in Montana and North Dakota, United States of America. We found that rates of parasitism of larvae in diapause chambers reached a maximum of 46%, exceeding the previously reported maximum of 2.5% in 75% of sites and years examined. In contrast to previous work, our results demonstrate that C. cinctus larvae are suitable hosts for braconid parasitoids, even after the formation of diapause chambers, and suggest that parasitism rates may be underestimated if stems are sampled prior to harvest.
