摘要
试验表明 ,小菜蛾性诱剂对小菜蛾种群的控制效应明显 ,但以低密度卵量下 (1～ 3粒 /株 )的控制效应较高 ,可达 70 %左右 ;不同蔬菜上小菜蛾用性诱剂的控制效果差异较大 ,在菜心和上海青上的控制效果较高 ,而在芥蓝和奶白上的控制效果较小 ,这主要与不同蔬菜上小菜蛾种群发生动态有关 ;在整个菜心生育期中 ,以 3个诱盆 /1 80m2 大棚的平均每盆诱捕雄蛾量最高 ;在 6造菜心上连续用小菜蛾性诱剂诱捕效果可保持在 70
Synthetic sex pheromone was very effective in controlling the population of diamondback moth, Plutella xylostella L in the green house When the synthetic sex pheromone was used under the low DBM egg density (1-3 eggs/per plant), 70% control effect was obtained Significant difference in control effect was found among different vegetable varieties The control effect in Chinese cabbage and Shanghai Qing was higher, than those in the pakchoi and Chinese kale More male moth was attracted when three sex pheromone traps/180m 2 were used in the experimental period A control effect of 70% was obtained when sex pheromone was used continuously for 6 plantings of Chinese cabbage
