肿腿蜂室内侵害的调查研究

Investigation on Bethylidae infestation indoors

目的认识肿腿蜂,防范其室内侵害。方法捕获标本,鉴定种类;粘捕法调查肿腿蜂的密度和分布,查找孳生场所,评价防治效果。结果捕获标本经鉴定为肿腿蜂、茎小蜂和剽蠹;孳生场所为橱柜,孳生场所清除2 d后,肿腿蜂的密度由3.83只/(张.d)下降到1.90只/(张.d)(Wilcoxon符号秩检验,P=0.03)。结论肿腿蜂外形易与蚂蚁混淆,需相互鉴别;随着肿腿蜂广泛应用于农林业的害虫防治,有关其室内侵害事件的报道越来越多,应引起重视。

Objective To have a knowledge and control of Bethylidae infestation indoors. Methods The spec- imen captured were identified, and the breeding place were searched based on its distribution and density by sticky traps, and the control effeet was evaluated after its breeding place removed. Results The specimen collected in the cupboard were belonged to 3 genera： Bethylldae, Cephidae and moth. The density of Bethylidae declined from 3.83 pieces per day to 1.90 pieces per day two days after the breeding place removed （ P = 0.03 ）. Conclusion Bethyl- idae are like ant in shape, but their life cycle and control measures are completely differet. With Bethylidae widely used in biological control, we should learn more about their infestation indoors.
