摘要
作者于1991年7～11月间,对丽蝇蛹集金小蜂进行了野外释放试验,选择以家蝇为主的孳生场所(酱糟),其中释放点、对照点各1个;将室内培养繁育的大量小蜂在释放点每周1次,共释放14次,累计释放小蜂数约为260654只,平均约18618只/周。结果显示,释放点家蝇密度下降59.9%,厩腐蝇下降32.2%,丽蝇科种类下降24.5%,麻蝇科种类下降14.5%,释放点该蜂在家蝇蛹的寄生率为41.6%,对照点为14.2%。作者认为,通过室内大批量繁育蝇蛹寄生蜂,在野外局部范围内定点、定时大量释放,可在一定程度上控制有害蝇类的种群密度。
The pupal parasite Nasonia vitripennis (Walker) was released for 14 weeks on field stack of soy diatillers: grains in Shanxi province for control of house fly and other filth flies. The decrease of the field: densities on the release site of house fly, stable fly, Calliphoridae species and Sarcophagidae apecies averaged 59.9%, 32.2%, 24.5% and 14.5%, respectively. Parasitism of house fly pupae averaged 41.6% on the release site and 14.2% on the check site. The strains of N. vitripennis used in this study were effective in controlling house fly populations under the conditions imposed and at the numbers released.
