利用田间调查的方法探讨了宽颊纹潜叶蜂(Kaliofenusa genata Wei)的发生规律及种群消长动态。结果表明,宽颊纹潜叶蜂能危害大叶榆、圆冠榆、白榆等多种榆树,并可在相应寄主上完成发育。成虫寿命较短,田间调查约10 d,成虫4月初开始羽化,至4月20日左右结束。成虫羽化后5~7 d 开始产卵,卵5~8 d 孵化,幼虫是危害榆树的唯一虫态,危害持续近1月,至5月20日前后幼虫全部落入土壤化蛹,蛹具滞育习性。

In this paper,the occurrence regularity and population dynamic Kaliofenusa genata Wei were discussed by the method of field investigation.The results showed that K .genata can damage a variety of elm,such as Ulmus laevis ,Ulmus densa and Ulmus pumila ,and can complete development in the corre-sponding host.Adults have short life,the average life was about 10 days.Adult emerged at the beginning of April.The eclosion stage completed around Apr.20.Adults lay eggs after eclosion 5-7 d,hatching began af-ter 5-8 d.the larva is the only state which can harm elm for a month,on May 20th all larvas fall into the soil to pupate and pupae have diapause habit.
