| 摘 要： | 1984—1988年在果园开展了利用松毛虫赤眼蜂防治苹果小巷叶蛾的试验示范,放蜂面积7万余亩,卵块和卵粒寄生率分别达92.41和87.29％,虫果率仅2—3％,效果好于化学防治。果园放蜂以每亩设8—12个点,放蜂4次,总蜂最12万头,效果较好。P~(32)标记证明,赤眼蜂的扩散距高,在6小时内有61.96％的蜂分布在5米范围内,而24小时后则比较均匀地分布到30米的范围。

| Abstract: | During 1984-1988, releases of T. dendrolimi was made in 70,000 mu (15 mu=1 ha.) of apple orchards in Shandong Province to control apple leafroller, Adoxophyes orana. The average parasitization of the egg masses and eggs of the pest was 92.41% and 87.2%, respectively, and the percent damaged fruits was reduced to 2-3%, a better control effect than by using chemical insecticides. The parasite was released four times a year on 8-12 releasing sites with a total of 120,000 wasps released per mu. Results of the dispersal study with P32 labeled wasps showed that 61.96% of the parasites dispersed within 5 m distance in the first 6 hr. of the release, and dispersed evenly to 30 m by 24 hr. |
