研究了上海地区危害月季的豆毒蛾的生活史和生活习性。室内条件下该虫一年发生2～3代,以幼虫越冬。幼虫期总食叶量6789.35mm~2,总取食量11张。室温在24℃时,完成一世代需要67.42d。其中卵期6d,幼虫期47.5d,预蛹期为1d,蛹期为9.25d和成虫(产卵前期)3.67d。雌雄成虫性比为1:1.29。室内卵平均孵化率为89.5％。越冬幼虫过冷却点-5.25至-6.78℃,结冰温度为-3.57至-4.65℃。通过室内药剂防治实验,得出6种药剂之中的4种药剂效果较好。
The life history and living habits of legume moths in Shanghai are studied. Indoor conditions of the pest occurs 2 to 3 generations a year, with larvae overwintering. The larvae total leaf volume 6789.35mm ~ 2, the total intake of 11. Room temperature at 24 ℃, the completion of a generation need 67.42d. Among them, the egg stage 6d, the larval stage 47.5d, the pre-pupal stage 1d, the pupal stage 9.25d and the adult (pre-oviposition stage) 3.67d. Male and female adult sex ratio of 1: 1.29. The average hatching rate of indoor eggs was 89.5%. Overwintering larvae sub-cooling point -5.25 to -6.78 ℃, freezing temperature of -3.57 to -4.65 ℃. Through indoor pharmacy prevention and control experiment, it is concluded that 4 kinds of medicaments among the 6 kinds of medicaments have a better effect.
