摘 要 【目的】 研究不同缓释载体对松墨天牛Monochamus alternatus信息化学物质诱捕效果的影响，为研发对昆虫信息素和寄主挥发物释放效果更好的仿生诱芯提供依据。【方法】 测试聚集性信息素不同缓释载体（低密度聚乙烯缓释袋、毛细管、橡胶头）对松墨天牛诱捕效果的影响，并选出最优载体，并设置不同厚度（0.06、0.08、0.12 和0.16 mm）缓释袋，进行进一步筛选。另外，测试植物源信息素不同缓释载体（0.08 mm低密度聚乙烯缓释瓶；0.12 mm低密度聚乙烯缓释瓶；0.15 mm低密度聚乙烯缓释瓶；0.15 mm高密度聚乙烯缓释瓶）对松墨天牛诱捕效果的影响。【结果】 低密度聚乙烯缓释袋作为松墨天牛聚集性信息素缓释载体，其对松墨天牛诱捕效果显著高于毛细管和橡胶头载体，且厚度为0.08 mm时的诱捕效果好于0.06、0.12和0.16 mm厚度的缓释袋。另外，0.12 mm低密度聚乙烯瓶作为植物源信息素缓释载体，对松墨天牛诱捕效果最好，显著高于0.15 mm低密度聚乙烯瓶以及0.15 mm高密度聚乙烯瓶。【结论】 低密度聚乙烯是一种适合松墨天牛信息化学物质的优良缓释载体，显著提高了松墨天牛引诱剂的诱捕效果，并为生产上相关昆虫信息化学物质选用适宜的缓释载体提供了技术支持。
英文摘要：
Abstract [Aim] To study the effects of different sustained release carriers on the semio-chemical lures used to trap Monochamus alternatus, and thereby provide a basis for the development of bionic lures with more sustained release of insect sex pheromones and host volatiles. [Methods] The effects of different sustained release carriers (LDPE caps, polymicro and rubber stoppers) on the persistence of sex pheromone lures were tested and different thicknesses (0.06, 0.08, 0.12 and 0.16 mm) of the optimal sustained release carrier compared. In addition, we tested the effectiveness of different density LDPE bottles (low-density 0.08 mm, low-density 0.12 mm, low-density 0.l5mm and high-density 0.15mm) and the effect of pheromone trapping effect on botanical pheromones. [Results] The LDPE cap was the best sustained release carrier, and the optimum cap thickness was 0.08 mm. In addition, low-density LDPE bottles performed significantly better than high-density LDPE bottles. [Conclusion] The type of sustained release carrier can significantly affect trap performance.
