虽然,这11种小蠹虫具有各自不同的生态位宽度,且存在不同程度的生态位重叠,但各小蠹虫可依据其对寄主树木营养和空间需求的不同、种群密度的相互制约,以及入侵寄主树木时序的差异达到竞争的平衡和共存。

In addition this paper,"Bio-Rad method," two parasitic wasps of the post-embryonic development the process of protein accumulation in young bees and the host Plutella xylostella in this process in vivo haemolymph protein content were measured and found that over time, was gifuensis parasitic larvae of the diamondback moth haemolymph protein content showed an upward trend in nearly a straight line, Ichneumonidae parasitic For example, in the early parasitic diamondback moth haemolymph protein content also showed the trend of slow growth, but in the mid-and late parasitic young bee about to be completed in the development of the host body when to stop feeding, a significant downward trend却呈, and significantly lower than the third day of its own protein content; on the same day of the different species of the diamondback moth parasitic wasp hemolymph protein content compared Ichneumonidae Parasitism of diamondback moth have hemolymph protein content than in the third and fourth day after the parasitic Braconidae hemolymph content to be high, but very different in the case of the fifth day, as evidenced by her side after the parasitic bee moth haemolymph protein content is cocoon of the parasitic bee hemolymph protein content of 0.7 times.

另外本文采用"Bio-Rad法"对两种寄生蜂胚后发育过程中幼蜂蛋白积累及寄主小菜蛾在此过程中体内血淋巴蛋白含量进行了测定,结果发现随时间的推移,被茧蜂寄生小菜蛾幼虫的血淋巴蛋白含量是呈近直线增加趋势,而对于姬蜂寄生来说,在寄生初期小菜蛾血淋巴蛋白含量也呈缓慢增长趋势,但在寄生中后期,幼蜂即将完成在寄主体内的发育取食停止时,却呈大幅下降趋势,且明显低于其自身第三天的蛋白含量;对同一天的被不同种寄生蜂寄生的小菜蛾血淋巴蛋白含量进行比较,姬蜂寄生过的小菜蛾血淋巴蛋白含量在第三天和第四天均比茧蜂寄生后的血淋巴含量要高,但在第五天的情况大不相同,表现为被姬蜂寄生后的小菜蛾血淋巴蛋白含量是被茧蜂寄生的血淋巴蛋白含量的0.7倍。
