蛹寄生

草原毛虫蛹期寄生天敌种类初步观察

A Preliminary Observation on the Natural Enemy Species in pupae of Grassland Caterpillar

结果表明，对小蠹幼虫的寄生率为20.70%，对小蠹蛹的寄生率为15.82%，对小蠹成虫的寄生率为1.71%。

The results are as follow : the parasitic rate of larvae , pupae and adults is 20.70 % , 15.82 % and 1.71 % respectively .

抚顺地区兴安落叶松鞘蛾ColeophoradahuricaFikv有寄生蜂11种，其中9种为老熟幼虫和蛹期寄生蜂，2种为1～2龄幼虫期寄生蜂。

There are ll species of parasitic wasps in Coleophora dahurica in Fushun and 9 of them parasitize in mature larvae and pupae , 2 of them in larvae of lst or 2nd instar .

分析了天敌寄生蜂的自然控制作用，发现天敌寄生蜂对小蠹幼虫的寄生率为5.41%，对小蠹蛹的寄生率为8.46%，对小蠹成虫的寄生率为0.33%

And the naturally control action has been analysised . the Results are as follow : the parasitic rate of larvae , pupae and adults is 5.41 % , 8.46 % and 0.33 % .

寄生蜂则对金堇蛱蝶种群的调控作用极小，只有在2003～2004世代有4.0%的越冬后幼虫被寄生和7%的蛹被寄生。

In contrast , parasitoids had little effect on the population regulation , because only 4 % of the post-diapause larvae and 7 % of the pupae were dead due to parasitoids in the 2003-2004 generation .

寄生蛹和未寄生蛹的血淋巴样品电泳凝胶扫描结果表明，寄生蛹和未寄生蛹的蛋白带也有明显差异。

The PAGE pattern revealed that the protein bands of hemolymph samples , from parasitized and the unparasitized pupae , were obviously different .

第1代的风雨致死，第2代的4－5龄幼虫及蛹的虫寄生，越冬代（即第3代）的打枣致死、蛹期天敌取食及冬季消亡对种群的控制作用较大；

The major controlling factors to the population were the death of 1st generation by rain and wind , of the 4th-5th instar larvae and pupae of 2nd generation parasitized by insects and of 3rd generation by picking fruit , natural enemies and dying out of winter ;

寄生后12h的寄生蛹与同期未寄生蛹的血淋巴可溶性蛋白浓度相差不大，而在寄生后1～4d，寄生蛹的血淋巴可溶性蛋白浓度明显高于同期未寄生蛹。

The concentration of hemolymph soluble protein in parasitized pupae was similar with that in un parasitized pupae at 12 hours after parasitization , and then , markedly higher than the latter .
