采用四臂嗅觉仪进行寄主和虫体聚集信息化合物对松纵坑切梢小蠹成虫的引诱活性测定。根据不同浓度各种单组分及复组分聚集信息化合物对不同时期成虫的引诱结果，认为供试的各种单组分化合物均有一定的引诱作用，但以复组分化合物的引诱效果较好，其中又以虫体和寄主信息化合物复配的效果最好。成虫梢转干时期是对聚集信息化合物最敏感的时期。初步确定了能够较好引起松小蠹成虫聚集行为的4种复组分聚集信息化合物引诱剂为MBXS+APX、APX+YS、MBXT +APX和APX+BPX+YS，引诱率分别达到87.4%、84.2%、82.8%和81.4%。适用时期为松小蠹成虫梢转干(11～2月)阶段。
Determination of Attractant Activity of Host Compounds and Insect Aggregates with Four - Arm Smellometer in Adults of Pinctada. According to the inducement results of adults and adults at different concentrations and concentration of various single-component and multi-component aggregated information compounds, it is considered that all the single-component compounds tested have some attractive effects. However, Well, among them the parasites and the host information compound compound is the best. Adult shoots turn dry period is the most sensitive gathering of information on the compound period. The results showed that the attractants of MBXS + APX, APX + YS, MBXT + APX and APX + BPX + YS were preliminarily identified. The attractant rates of the four compounds were 87.4% 84.2%, 82.8% and 81.4%. The applicable period for the pine beetle adult tip dry (11 ~ February) stage.
