1982～1985年,在广西武鸣华侨农场进行保护利用瓢虫控制蔗田绵蚜为害试验。主要措施是保护安全越冬、越夏。冬季室内饲养,室温18～20℃,相对湿度75～85％;翌年4月,大突肩瓢虫越冬存活率为62,96～82.92％;双带盘瓢虫存活率45.71～100％。保护安全越夏的最适室温为23～26℃,相对湿度75～85％,大突肩瓢虫越夏存活率为69.13％(当年第一代成虫)和53.8％(越冬代成虫)。双带盘瓢虫抗逆性较强,在一般室内即能越夏。4年来累计释放两种瓢虫的成、幼虫共44661头,防治蔗田绵蚜效果明显,减少蚜害株率96.6％、蚜害叶片率90％。
From 1982 to 1985, protection was conducted in Wuming Huaqian Farm, Guangxi using the ladybug to control the cotton aphid infestation. The main measure is to protect the safety of winter, summer. Winter indoor feeding, room temperature 18 ~ 20 ℃, relative humidity 75 ~ 85%; the following April, the survival rate of the sudden shoulder ladybug overwintering was 62,96 ~ 82.92%; double reel ladybug survival rate 45.71 ~ 100%. The optimum room temperature for protection and safety in summer is 23-26 ℃ and relative humidity of 75-85%. The summer survival rate of Buchholzidormidae is 69.13% (first-generation adult in that year) and 53.8% (adult overwintering). Double-band ladybug strong resistance, that is, the general indoor summer. In the past four years, a total of 44661 larvae were released from two lady beetles. The effect of controlling cotton aphid was obvious, reducing the rate of aphid strains by 96.6% and the rate of leaf aphids by 90%.
