摘　　要：为解决落叶松种子严重短缺的问题，利用５％杀铃脲乳油、２５％灭幼脲Ⅲ号悬浮剂、２０％杀铃脲悬浮剂、５％伏虫灵乳油和３０％辛脲乳油等昆虫生长调节剂，在大兴安岭进行了落叶松球果花蝇（Ｓｔｒｏｂｉｌｏｍｙｉａｓｐｐ．）防治试验。试验结果表明，球果被害率可减少２０％～８０％，种子被害率减少３５％～４０％。由球果和种子被害率分析可见，二次施药的防治效果明显好于一次施药的防治效果。To solve the problem of the seeds shortage of Larix , 5 kinds of insects growth regulators such as 5% triflumuron emulsifiable concentrate, 25% benzoylphenol No.3 flowable formulation, 20% triflumuron flowable formulation, 5% hexaflumuron emulsifiable concentrate, 30% phoxin and benzoylphenol No.3 emulsifiable concentrate have been used in the controlling of Strobilomyia spp. in Daxing′anling, Northeastern China in 1998. The results of these experiments showed that spraying these insecticides which diluted 500, 1000 or 1500 times with water at the peak period of the emergence and eggs laying of Strobilomyia spp. could reduce 20% to 80% cone damaging rate and 35% to 40% seed damaging rate. Spraying those insecticides two times in the peak time of eggs laying could get much better result than only spraying one time.
