摘　　要：为提高二疣犀甲聚集信息素的使用效率,为该虫的物理防治策略制定提供参考,对二疣犀甲的非成虫期发育场所进行了调查,并研究了椰子半腐烂茎干提取物与二疣犀甲聚集信息素的协同应用效果。结果显示:共在8种场所发现二疣犀甲的不同虫态,包括棕榈茎干腐烂物、锯末堆、椰糠和粪肥混合物等;以椰子半腐烂茎干为提取原料,供试溶剂中以甲醇和乙醇对浸提物的提取率最高,分别为13.11%和11.66%,采用水蒸气蒸馏法对挥发物提取率为0.03%;不同溶剂浸提物处理中,以石油醚浸提物诱集到的虫口数量较多,为3.33头;挥发物平均诱集虫数为8.67头;添加挥发物后,显著增加了二疣犀甲聚集信息素对成虫的诱集总量,增效率为45.83%;添加浸提物和挥发物均显著增加了信息素对二疣犀甲雌虫的诱集效果。本研究结果可为二疣犀甲聚集信息素的高效利用及相关增效产品的研发提供参考。To improve the efficiency of the use of an aggregation pheromone and provide a reference for the physical control strategy of O. rhinoceros, the nonadult development sites of the O. rhinoceros were investigated, and the synergistic effects of the coconut semi-rotten stem extracts on O. rhinoceros aggregation pheromones were studied. Different stages of O. rhinoceros infection were found in eight places, including palm rotten stems, sawdust piles, coconut coir, manure mixtures, etc. Using coconut semi-rotten stems as a raw material for extraction, methanol and ethanol had the highest educt extract rates of 13.11% and 11.66% among the solvents tested and the volatile extraction rate by hydrodistillation was 0.03%. Among the treatments with different solvent extracts, the educt of petroleum ether trapped the highest number of adults was 3.33. The average number of insects trapped by volatiles was 8.67. The addition of volatiles significantly increased the trapping effect of aggregation pheromones on the total number of adults, for a 45.83 % increase. The addition of educt extract and volatiles significantly increased the attraction effect of pheromones on female adults. The results provide a reference for the efficient application of O. rhinoceros aggregation pheromone and the research and development of related synergistic products.
