摘要
在信丰林区连续2 a研究了营林措施对萧氏松茎象种群的控制作用。结果表明:2010～2011年试验区萧氏松茎象当年虫口密度平均分别下降85.3%%和85.0%;相对防治效果平均分别为85.9%和86.0%;而对照区当年虫口密度分别上升4.4%和29.4%。这说明营林措施能明显抑制萧氏松茎象种群的上升。
The role of silvicultural measures control on Hylobitelus xiaoi Zhang population in Xinfeng forests was studied for 2 consecutive years.The results showed that： during 2010 to 2011,the population density of H.xiaoi Zhang in test area decreased by an average of 85.3%% and 85.0%.Average relative control effect was 85.9% and 86.0%;while the population density increased by 4.4% and 29.4% in the control area.This showed that silvicultural measures could significantly inhibit the increase of H.xiaoi Zhang population.
