越冬代竹斑蛾预蛹天敌种类及动态

在竹斑蛾大发生后,分批采集越冬代预蛹茧于室内饲养,获得寄生性天敌11种,有白僵菌1种、寄蝇3种、寄生蜂7种,寄蝇、寄生蜂全部是寄主新记录,其中在姬蜂科中发现2个中国新记录属、1个中国新记录种.11种寄生性天敌中有4个优势种,其寄生率各自均占总寄生率10%以上.特别是新拟秘姬蜂,寄生率占总寄生率47%,估计在竹林中竹斑蛾越冬茧阶段可繁殖3代.

Species and Population Dynamics of Natural Enemies of Prepupa of Artona funeralis in Overwinter Generation

A lot of prepupae of Artona funeralis were collected in succession after they broke out in a large area and were reared in the lab. during the process, 11 species of parasitic enemies, 1 white muscardine fungi, 3 parasitic flies and 7 parasitic chalcids were discovered. All the parasitic flies and chalcids collected are new record enemies of A. funeralis in China. Two newly-recorded genus, Diaglyptidae Vieredc and Caenocryptoides Vchida and 1 newly-recorded species, Theronia depressa were discovered. There were 4 dominant species among the 11 parasitic natural enemies, and the parasitic rate of each enemy is over 10%. Extraordinarily, the parasitic rate of C. sp. is 47%. C. sp. could complete 3 generations during the period of prepupa for overwintering of A. funeralis in bamboo forest.
