摘要
本文比较研究了尖钩宽黾蝽不同翅型成虫的生殖力。试验结果表明，尖钩宽黾蝽无翅型成虫和有翅型成虫如果取食褐飞虱低龄若虫时，在产卵前期、产卵期、产卵量、卵历期、卵孵化率及雌、雄成虫寿命等均无显著性差异；如果取食白背飞虱低龄若虫时，无翅型成虫的产卵量显著高于有翅型，但在其他几个方面则无显著性差异。最后比较了尖钩宽黾蝽不同翅型的生殖指标。
This paper deas with studies of comparison of reproductive capacity of Microvelia horvathi adults with different wing forms. The results showed that when feeding on low-instar nymphs of white planthopper, Sogatella furcifera (WBPH), different wing forms adults of this natural enemy had no significant differences in female and male adults longevity, preoviposition duration, oviposition duration, egg period and egg hatchability, but had obviously difference in total numbers of eggs. Total numbers of eggs laid by apterous adults fed on WBPH Were obviously more than that of pterygote adults. But when fed on low-instar nymphs of brown planthopper, Nilaparvata lugens, apterous and pterygote adults of M.horvathi had no significantly different in those indexes mentioned above. Meanwhile, reproductive index of adults of the enemy was also compared.
