中文摘要：在木材检疫中利用对白蚁有引诱作用的几种物质，进行不同的配比，对白蚁的食物选择性进行研究。室内结果表明：在5种配比中TB04(甘蔗粉+棕檬醛)的效果最好，其取食率、泥被面积及泥被覆盖率分别达到47.74%±4.69%、(8.06±0.18)cm2和89.53%±1.96%。室外诱集试验表明：TB03(甘蔗粉+木耳粉)、TB04均有较好的效果。温湿度试验表明：大家白蚁Coptotermes curvignathus Holmgren取食的最佳温度为23～29℃，湿度高的条件下的诱集效果明显高于干燥条件下的诱集效果。诱集时间试验表明，随着时间的延长诱集效果逐渐明显，72 h诱集数量趋于稳定。
英文摘要：Several baits with different components had been chosen to study the food choice of termite Coptotermes curvignathus Holmgren in timber quarantine. The results showed that TB04 was the best, in which sugarcane powder and citral were contained. The consumption rate, mud sheet area and mud sheet covering rate were 47.74%±4.69%, (8.06±0.18) cm2 and 89.53%±1.96%, respectively. The results of the field trial showed that TB03 containing sugarcarne and agatic powder and TB04 had good effects. The turther trials showed that the optimal temperature for trapring was 23～29℃, and the humid condition was better than dry condition. The trapping effect increased with the time lasting, and the number of termites tended to be constant after 72 hours.
