摘要
对大规模繁殖白蛾周氏啮小蜂Chouioia cunea时寄主或替代寄主的接蜂比例的选择进行了研究。结果表明, 以美国白蛾Hyphantria cunea为寄主时,接蜂时寄主与寄生蜂的比例以1:1和1:2为宜。以柞蚕Antheraea pernyi为寄主时,寄主与寄生蜂的比例以1:50为宜,繁殖出的小蜂田间平均寿命约为6 d。过多地增加接蜂数量,会影响到子代的出蜂数量和雌雄性比等。
The choice of best ratio of host and wasps when mass rearing of Chouioia cunea was studied. The result showed that 1 ： 1 or 1 ： 2 were the choice of the ratio of hosts and wasps when choosing fall webworm as a host and 1：50 when choosing Antheraea pernyi as a host to mass rearing C. cunea. The longevity of C. cunea reared according to this ratio was about 6 days on average in field, which could guarantee them to find suitable hosts. To improperly increase the percent of wasp would have a bad influence on the quantity or ratio of female and male of next generation.
