摘要:

解剖发现,白蛾周氏啮小蜂Chouioia cunea Yang的雌性成虫具一对卵巢,每个卵巢的卵巢管数目为6-10根,且有时左右卵巢管的数目不等; 一个卵巢管中的卵数为8-34粒.卵巢内总含卵数可达680粒,实际平均为270.5粒。证明了该种寄生蜂具有较大的繁殖潜力。

Abstract:

It was revealed by internal anatomy that the female of Chouioia cunea Yang has a pair of ovaries. Each ovary consists of ovarioles from six to eight. The number of ovarioles sometimes is different in both ovaries even within one individual female. A mature ovariole contains eggs from eight to thirty-four. The maximum of total eggs within ovarioles in a female could reaches 680 and on an average 270.5 in t6 dissected individual females.
