红脂大小蠹驱避剂应用技术的研究

Study on Application Effects of Repellent on the Response of Dendroctonus valens

对bubb lecaps和punches两种释放速率的红脂大小蠹驱避剂,分别采用间隔5,10 m和10,20 m的间隔距离,在太岳林局龙泉林场进行了野外试验,结果表明:punches驱避剂间距离20 m处理能最佳增加红脂大小蠹诱捕量;同时无论punches还是bubb lecaps驱避剂在5 m和10 m距离间对增加红脂大小蠹诱捕量都有一定效果。使用驱避剂对植物性信息素引诱其他昆虫种群无影响。

Two repellents （bubblecaps and punches） to Dendroctonus valens, with different release speed, was placed at a space of 5 m or 10 m, and 10 m or 20 m in the Longquan Forest Farm in the Taiyue Forest Bureau. The results show that, punches repellent at a space of 20 m can repel more Dendroctonus valens insects to insect trapper than other test treats. Both bubblecaps and punches at a space of 5 m or 10 m have better effect on repelling insects. The repellents have no effects on other plant pheromones attracts insects.
