摘要: 以豆蚜(Aphis craccivora K.)为饵料,研究相同饲养密度下,七星瓢虫(Coccinella septempunctata L.)不同雌、雄比例对其产卵量及孵化率的影响,并以3∶1作为优选出的雌、雄比例,研究1 000 mL容器内饲养不同密度七星瓢虫对其产卵量及孵化率的影响。结果表明,雌、雄比例为1∶1、2∶1和3∶1时七星瓢虫的产卵量显著高于雌、雄比例为4∶1和5∶1时七星瓢虫的产卵量;以3∶1为雌、雄比例,在1 000 mL的容器中,饲养9雌3雄时,产卵量显著高于饲养3雌1雄、6雌2雄、12雌4雄、15雌5雄;雌、雄比例及饲养密度对孵化率无显著影响。

Abstract: Using Aphis craccivora K. as the diet, the effects of different female-male ratios on the laying capacity and hatchability of Coccinella septempunctata under the same feeding density were studied. And using the ratio of 3∶1 as the preferred female-male ratio, the effect of raising Coccinella septempunctata of different densities in a 1 000 mL container on its spawning volume and hatchability was studied. The results showed that spawning volume by Coccinella septempunctata was significantly higher when the female-male ratios were 1∶1, 2∶1 and 3∶1 than those of 4∶1 and 5∶1. With a female-male ratio of 3∶1, the spawning volume of 9 females and 3 males in a container of 1 000 mL was significantly higher than that of 3 females and 1 male, 6 females and 2 males, 12 females and 4 males, 15 females and 5 males. The female-male ratios and the feeding density had no significant effect on hatchability.
