摘　　要：1997～ 1999年 ,在不同试验点的云南松蠹害林分中设置饵木堆、整株饵木和活立木引诱松小蠹试验。研究结果表明 ,几种方法对松小蠹均有一定的引诱效果。设置的衰弱木饵木堆诱虫效果明显高于健康木饵木堆 ;在饵木堆上加置MBXS ,(- )APX或 (- )APX +YS复合剂 ,诱虫量比不加置这些聚集信息化合物的饵木堆增加 4倍以上。试验所用窗式诱捕器以寄主天然化学气味物质为诱饵 ,对转干期成虫具有较高而稳定的诱捕量 ,且设置检查方便、价格低廉 ,适用于梢转干期林间松小蠹诱捕和种群动态监测 ;活立木上加置 (- )APX +YS复合剂 ,对各时期松小蠹成虫均有一定引诱作用 ,可用于梢部小蠹种群动态监测。Tomicus piniperda trapping experiments were conducted in the damaged Pinus yunnanensis stand at different sites by setting trap log piles,trap log and living tree.The results indicated that all the three tested baits had trap effect on Tomicus piniperda.The trap effect of asthenic trap log piles was significantly higher than that of healthy trap log piles.Adding MBXS,(-)APX or (-)APX+YS could increase the amount of trapped Tomicus piniperda by 4 times.The window shaped trapper which utilize the natural volatile odor substance of host tree as the bait,had good and stable trapping effect on the Tomicus piniperda flying from shoots to trunk.It is an economical and convenient method for monitoring Tomicus piniperda populations during the flying stage from shoots to trunk.Living trees with (-)APX+YS could trap Tomicus piniperda flying both from shoots to trunk and trunk to shoots,this method could be used to monitor Tomicus piniperda populations at the two flying stage of Tomicus piniperda adults.
