普通瑟姬小蜂生物学特性初步研究

Preliminary study on biological character of Cirrospilus pictus

首次发现普通瑟姬小蜂可寄生于枸杞瘿螨虫瘿内。通过对普通瑟姬小蜂的形态特征、与枸杞瘿螨种群消长规律、温度及补充营养对其寿命的影响、温度对其羽化的影响、蛹期耐冷藏性等的初步研究表明,其6月中旬对枸杞瘿螨的寄生率最高可达80.8%;成蜂寿命随温度升高逐渐缩短,补充15%蜂蜜水,可显著延长;最适羽化温度为24℃,随冷藏天数增加,羽化率逐渐降低。

It was found that Cirrospilus pictus Nee can parasitize in cecidium ofAceriapollida Keifer for the first time. By preliminarily studying on morphological character of Cirrospilus pictus Nee, its population dynemics in Aceria pollida Keifer, effect of temperature and nutrition supplement on its life-span, effect of temperature on its emergency and cold-resistant of its pupae, it was indicated that parasite rates reached the peak of 80.8% in middle of June, adult life-span was shortened with rise of temperature, and it was prolonged remarkably by being supplied with 15% honey-watgr solution, the best temperature for emergency is 24℃, and emergency rates decreased with increasing of cold treatment days.
