本文报告1991年对拟啮小蜂(Tetrasticdodes sp.)产卵习性等实验室观察结果。1、对雌蜂在蜚蠊卵荚上的产卵习性作了详细描述;2、对雌蜂在新老美州大蠊卵荚产卵的选择习性用两种实验方法作了观察,显示雌蜂均偏向新卵荚产卵;3、卵荚龄与寄生蜂寄生有密切关系,但直接关系是温度和蜚蠊卵子的胚胎发育进程。平均室温31.2℃时,拟啮小蜂可在0—17天龄的卵荚中完成寄生;平均室温27.5℃时,可在0—20天龄卵荚中完成寄生。 This article reports laboratory observations of the spawning habits of Tetrasticdodes sp. In 1991. 1, the female had been described in detail on the spawning habits of cockroach eggs and pods; 2, the selection habit of female bees laying eggs in the cockroaches in the old and new states was observed by two experimental methods, The bees tend to lay eggs on the new egg pods; 3) the age of the pods is closely related to the parasitoid parasitism, but the direct relationship is the temperature and the process of embryonic development of the cockroach eggs. At an average temperature of 31.2 ° C, parasitic wasps were found in oysters 0 to 17 days of age; at an average room temperature of 27.5 ° C parasites were completed in 0-20 day-old oods.
