摘　　要：2011—2013年在吉林省长白山林区利用人工合成的聚集信息素诱捕器,进行大量诱杀防治云杉八齿小蠹Ips typographus的效果研究试验。结果表明:经过连续3 a防治,云杉八齿小蠹聚集信息素诱捕器的诱集量下降了86.42%,与对照区相比防治区枯死木和衰弱木增长率减缓了82.36%。进一步证明利用聚集信息素大量诱捕能减轻云杉八齿小蠹危害、减缓扩散速度,是有效的治理手段。Efficacy of aggregation pheromone against spruce bark beetle,Ips typographus,was tested by mass trapping from 2011 to 2013 in Changbai Mountain area,Jilin province. After three years＇ mass trapping the trapping amount reduced by 86. 42%,meanwhile the increasing rate of the died and wea kened spruces in the treated areas slowed down by 82. 36% compared to that in the control areas. The results further suggest that mass trapping was an effective measure for controlling Ips typgraphus in terms of reducing bark beetle damage and retarding bark beetle spread.
