| 摘 要： | 采用物候期与信息素监测相结合的方法,研究了云杉八齿小蠹的扬飞规律。结果表明:林间云杉八齿小蠹成虫开始活动时,忍冬和紫丁香的花蕾出现、接骨木和东北茶藨子进入开花初期、蒲公英处于开花盛期;当榆叶梅进入开花初期、紫丁香进入开花盛期时林间虫口密度达到最高,是信息素诱集防治的最佳时机;当接骨木进入开花盛期时,整个扬飞期结束。

| Abstract: | Emergence dynamics of Ips typographus Linnaeus was investigated with sex pheromone combining with phenophase observation.The results showed that when Lonicera japonica and Syringa oblata were in bud,Sambucus williamsii and Ribes manschuricum var.manschuricum were in early bloo-ming and Taraxacum mongolicum was in full blooming,the adults began to emerge;when Amygdalus triloba was in early blooming and S.oblata was in full blooming,the population desity was in the peak,when was the best opportunity to trap t... |
