摘要
为了掌握美国白蛾周氏啮小蜂在林间的释放技术,确定日间段适宜的放蜂时间和树体挂蜂较好的方位,作了日间不同时间段和不同挂蜂方位美国白蛾周氏啮小蜂对美国白蛾蛹寄生率效果的研究。试验结果表明,美国白蛾周氏啮小蜂对美国白蛾蛹的寄生率与挂蜂日间不同时段的时间有关,与树体上挂蜂的不同方位无关,最佳放蜂时间为每日傍晚17：00-18：00时,或清晨4：00-6：00时。
In order to master releasing techniques of Chouioia cunea and ascertain suitable daytime segment of parasite releases and better azimuth for hanging bee, different times and different azimuth for hanging bee of Hyphantria cunea on parasitic rate of Chouioia cunea were studied. The results show that Hyphantria cunea has relation with parasitic rate and different times during daytime and has no relation with different azimuth. The optimal time of parasite releases is at 17：00-18：00 p. m. , or 4：00-6：00 a. m, .
