摘　　要：栎空腔瘿蜂Trichagalma glabrosa Pujade-Villar&Wang在安阳1 a发生1代,以成虫越冬。有性世代成虫出现在4月中旬,产卵于栓皮栎Quercus variabilis嫩叶侧脉上,幼虫孵化后刺激叶脉产生球状虫瘿并在虫瘿内取食危害,幼虫于9月上旬开始化蛹,11月上旬成虫羽化出孔。虫瘿饲养观察发现,栎空腔瘿蜂有3种寄生性天敌:长尾小蜂Torymus sp.、刻腹小蜂Ormyrus sp.和旋小蜂Eupelmus sp.;2种寄居昆虫Synergus sp.和Cuyculio sp.。Trichagalma glabrosa Pujade-Villar Wang,1912 is a new pest phytophagous and harmful to Quercus variabilis.It has one generation a year in Anyang and overwinters as adult.The undescribed sexual adults emerge in mid April and lay eggs in the lateral vein of tender leaves.The larvae stimulate the veins to produce globular galls and pupate in early September.The adults emerge in early November.Three parasitoids,Torymus sp.,Ormyrus sp.and Eupelmus sp.,2 inquiline insect,Synergus sp.and Cuyculio sp.,were observed in gall feeding.
