Native to China and Korea, the Asian longhorned beetle, Anoplophora glabripennis (Motschulsky) (Coleoptera: Cerambycidae), is a polyphagous wood-boring pest for which a trapping system would greatly benefit eradication and management programs in both the introduced and native ranges. Over two field seasons, a total of 160 flight intercept panel traps were deployed in Harbin, China, which trapped a total of 65 beetles. In 2012, traps using lures with a 1:1 ratio of the male-produced pheromone components (4-(n-heptyloxy)butanal and 4-(n-heptyloxy)butan-1-ol) designed to release at a rate of 1 or 4 milligram per day per component in conjunction with the plant volatiles (-)-linalool, trans-caryophyllene, and (Z)-3-hexen-1-ol caught significantly more A. glabripennis females than other pheromone release rates, other pheromone ratios, plant volatiles only, and no lure controls. Males were caught primarily in traps baited with plant volatiles only. In 2013, 10× higher release rates of these plant volatiles were tested, and linalool oxide was evaluated as a fourth plant volatile in combination with a 1:1 ratio of the male-produced pheromone components emitted at a rate of 2 milligram per day per component. Significantly more females were trapped using the pheromone with the 10-fold higher three or four plant volatile release rates compared with the plant volatiles only, low four plant volatile + pheromone, and control. Our findings show that the male-produced pheromone in combination with plant volatiles can be used to detect A. glabripennis. Results also indicate that emitters should be monitored during the field season, as release rates fluctuate with environmental conditions and can be strongly influenced by formulation additives.
亚洲长角天牛(Anoplophora glabripennis (Motschulsky),鞘翅目:天牛科)原产于中国和韩国,是一种多食性蛀木害虫,诱捕系统将极大地有助于其传入地和原产地的根除及管理计划。在两个野外季节中,中国哈尔滨共部署了160个飞行拦截板诱捕器,共捕获了65只甲虫。2012年,使用含有雄性产生的信息素成分(4-(正庚氧基)丁醛和4-(正庚氧基)丁-1-醇)比例为1:1的诱芯的诱捕器,设计为每种成分每天释放1或4毫克,并结合植物挥发物(-)-芳樟醇、反式石竹烯和(Z)-3-己烯-1-醇,捕获的光肩星天牛雌虫显著多于其他信息素释放速率、其他信息素比例、仅使用植物挥发物以及无诱芯对照的情况。雄虫主要在仅用植物挥发物诱饵的诱捕器中捕获。2013年,测试了这些植物挥发物10倍的更高释放速率,并评估了氧化芳樟醇作为第四种植物挥发物,与以每种成分每天2毫克的速率释放的雄性产生的信息素成分1:1比例相结合。与仅使用植物挥发物、低浓度四种植物挥发物 + 信息素以及对照相比,使用具有10倍更高的三种或四种植物挥发物释放速率的信息素捕获的雌虫显著更多。我们的研究结果表明,雄性产生的信息素与植物挥发物相结合可用于检测光肩星天牛。结果还表明,在野外季节应监测发射器,因为释放速率会随环境条件波动,并且会受到配方添加剂的强烈影响。
