摘要
该文通过对春尺蠖ApocheimacinerariusErschoff羽化特性研究表明 ,成虫期与气温密切相关。邻近城区比郊外大田羽化期早 7～ 10d ;发蛾初期雄蛾多于雌蛾 ,以后雌蛾增多 ;成虫为全日程羽化出土 ,雌雄性比为 1∶1 4 2 ;雌蛾交尾最多可达 3次 ,雄蛾仅 1次。研究结果还表明 ,应用佳多频振式杀虫灯诱捕春尺蠖雄蛾数量大 ,日均单灯诱蛾量为 142 5 6头 ,单灯 1夜最高诱蛾2 4 71头 ,并诱到少量雌蛾。灯距 12 0m范围内 ,树干表皮单位面积上的有效卵率较无灯对照区下降了 2 4 %～ 61 5 % 。
The emergence of Apocheima cinerarius was closely relative to climate.The adult emerged 7 to 10 days earlier in the area near the city proper than in the field of outskirts.Males were more than females in the early stage of emergence and then females began to increase.The adult emerged all day.The ratio of female to male was 1∶1 42,Most of the moths trapped by Jiaduo Frequency Trembler Grid Lamps were males.Each day 1425 6 moths were trapped by one lamp.
