落叶松八齿小蠹卵、幼虫、蛹、成虫产卵及补充营养期均在落叶松皮内度过，仅在寻找寄主、越冬等阶段在皮外度过。根据该虫生物学的这些特性，我们分别研究筛选了杀皮内药剂、驱避药剂和杀越冬成虫药剂。结果表明，利用５０％氟氯菊脂、２０％的菊马乳油、８０％ＤＤＶ等药剂杀皮内小蠹虫效果均达９０％以上；利用敌百虫等药剂杀越冬等暴露在外的成虫效果可达１００％；利用速灭杀丁、一扫光等药剂驱避效果５天内可达１００％，至３０天仍可达７０％以上。１９９４—１９９５两年结合营林共防治５７０ｈｍ２，挽回经济损失达２９４．８０万元。
Larix oval beetles eggs, larvae, pupae, adults spawning and nutritional supplements are spent in the larch skin, only to find the host, overwintering stage spent in the skin. According to the characteristics of the worm biology, we have separately screened the anti-skin agents, repel agents and overwintering adult insecticides. The results showed that 50% of the chlorfenapuram, 20% of the Daisy EC, 80% DDV and other agents to kill bark beetle effect reached more than 90%; the use of trichlorfon and other agents to kill overwinter adult exposed to the effect of Up to 100%; the use of speed kill K, swept away the effects of agents such as repellent up to 100% within 5 days, up to 30 days still up to 70%. In 1994-1995, a total of 570hm2 of prevention and control of forests was jointly administered in the two years to restore economic losses of 2.9478 million yuan.
