温度对螟黄赤眼蜂不同品系的影响

在室内不同发育温度下,对螟黄赤眼蜂3个品系在柞蚕卵上的发育历期、有效积温、寄生率、羽化出蜂率、单卵蜂数和雄蜂率进行了初步试验研究。分析比较得出,3个品系之间存在较大差异,TC品系在不同温度下均优于其它两个品系,在工厂化大量繁殖上具有应用价值。

Effect of Temperature on Strains of Trichogramma chilonis

Under different growth temperature,the effective accumulation temperature,the parasitic rate,the eclosion rate,the number in the single host egg,sex rate on three strains of Trichogramma chilonis to tussah eggs was performed in the laboratory.The results were summa-rized as follows:Much difference existed in three strains and TC strain was the best under dif-ferent growth temperature,and showed that it had application in the factory reproduction in large scale.
