| 摘 要： | 本文在实验室内系统研究了多异瓢虫不同龄期幼虫、不同日龄雌、雄成虫对棉黑蚜的捕食能力。结果表明，多异瓢虫幼虫对棉黑蚜的日捕食量随龄期的增大而增多，1~4龄幼虫的日捕食量分别是17.20头、50.70头、121.50头和153.90头。多异瓢虫不同日龄雌、雄成虫对棉黑蚜的日捕食量呈先上升后逐渐降低的趋势，5日龄雌、雄成虫对棉黑蚜的日捕食量最高，分别为145.90头和157.30头。此外，同一性别不同日龄的成虫对棉黑蚜的日捕食量差异显著，同一日龄的雌虫与雄虫对棉黑蚜的日捕食量差异显著。以上研究表明多异瓢虫高龄幼虫和成虫对棉黑蚜具有较强的捕食能力，这为利用多异瓢虫防治棉黑蚜提供重要的理论基础。

| Abstract: | In this study, the predation capacity of ladybeetle Adonia variegate (Goeze) larvae at various instars, female and male adults at different ages on cotton black aphid Aphis atrata Zhang were systematically studied in the laboratory. The results showed that the predation amount of ladybeetle larvae on cotton black aphid increased with increasing larval instar, and the predation amount of 1-4 instar were 17.20 aphids, 50.70 aphids, 121.50 aphids and 153.90 aphids per day, respectively. In addition, the predation amount of ladybeetle adults at different ages on cotton black aphid were firstly increased and then gradually decreased, the peak predation amount was 5 days-old female and male adults (female:145.90 aphids per day, male:157.30 aphids per day). Significant difference were found for the predation amount of ladybeetle adults at different ages within the same gender, and there are significant difference for the predation amount of female and male adult at the same age. These results provide an important theoretical basis for the application of ladybeetles to the control of cotton black aphid. |
