    Parasitic Effect of Diachasmimorpha longicaudata on Bactrocera dorsalis

      摘要
    • 摘要: 通过组建前裂长管茧蜂的实验种群生殖力生命表,结果表明,前裂长管茧蜂羽化后有1～3 d不等的产卵前期,生殖活动的高峰期出现在羽化后的4～10 d,单日寄生桔小实蝇幼虫量不超过20头,平均每头雌蜂约能繁育125个后代.种群中以雌性个体为主;雌雄比例接近2:1.世代净增殖力和内禀增长率分别为44.44和0.158 1.田间放蜂试验结果表明,当按1:1、1:5及1:10的蜂虫比释放时,15 d后的寄生率分别为36.01%、12.50%和5.18%,但随后寄生率急剧下降.

       

      Abstract: The reproduction biology of Diachasmimorpha longicaudata was studied by construction of experimental population life table of D.longicaudata reared in oriental fruit fly,Bactrocera dorsalis.D.longicaudata had a pro-oviposit period for 1 to 3 days,depending on adult's food and copulation.The peak of reproduction activity appeared in 4 to 10 days after adult emergence,and one female could breed about 125 offspring,however,the number of daily parasitized larvae of D.longicaudata was no more than twenty.The net...
