摘要: 栎空腔瘿蜂Trichagalma acutissimae(Monzen)是危害栓皮栎Quercus variabilis Blume叶片的重要林业害虫,为我国新纪录种。近年来,在南太行山区的栓皮栎林内暴发成灾,长尾小蜂Torymus sp.是栎空腔瘿蜂的一种主要寄生性天敌,为明确栎空腔瘿蜂及其天敌长尾小蜂种群数量消长动态,为预测预报和综合治理提供依据,本文调查了栎空腔瘿蜂和长尾小蜂成虫种群动态以及长尾小蜂的寄生率。结果表明,长尾小蜂成虫种群数量及寄生率一年发生2个高峰,第1个高峰发生在5月中旬,第2个高峰发生在7月下旬;2011—2015年,无性世代虫瘿平均每株发生的数量分别为826.0、816.4、61.8、11.0和3.4个,平均每块粘虫板长尾小蜂成虫发生数量分别为39.00、46.33、19.30、13.33和8.30头,长尾小蜂总寄生率分别为39.7%、51.0%、61.1%、54.9%和29.5%。

Abstract: Trichagalma acutissimae (Monzen) (Hymenoptera: Cynipidae) is a major pest of Quercus variabilis Blume in the Taihang Mountains in China. Torymus sp. is a parasitoid of T. acutissimae. Population dynamics of T. cutissimae and the parasitoid was surveyed for purpose of outbreak early warning and integrated pest management. There were annually two peaks of T. cutissimae adult population and parasitic rate, the first in mid-May and the second in late July. Form 2011 to 2015, the number of galls of asexual generations of T. cutissimae was 826.0, 816.4, 61.8, 11.0 and 3.4 per 3 leaves per year, the number of parasitoid adults was 39.00, 46.33, 19.30, 13.33 and 8.30 each sticky board per year, and total parasitic rate was 39.7%, 51.0%, 61.1%, 54.9% and 29.5%, respectively.

Key words: Trichagalma acutissimae, Torymus sp., population dynamics, parasitism rate
