Heterocrossa rubophaga, the raspberry bud moth, is a pest of commercial Rubus berry crops and wild Rubus species. Its pheromone was initially identified as a single component, (7Z)-nonadecen-11-one. Here we report further investigation of this carposinid pheromone including volatile collection, gland extraction, mass spectrometry, microchemical analysis, electrophysiology and field testing. The alkene (7Z)-tricosene was identified from female gland extracts and the synthetic compound gave antennal responses from the male moth. Field testing of (7Z)-tricosene showed that it was unattractive alone but in combination with (7Z)-nonadecen-11-one it more than doubled male moth trap catch for all doses tested compared to that of (7Z)-nonadecen-11-one alone. We recommend a blend of 300 µg of (7Z)-nonadecen-11-one and 300 µg of (7Z)-tricosene as an improved monitoring tool for raspberry bud moth for use by berry growers. This is the second report of the Z-alkene as a pheromone component in the Carposinidae family among the three carposisnid pheromones identified to date.

（7Z）-Tricosene改善了覆盆子蛾，杂交红线虫的信息素陷阱捕获。

覆盆子芽蛾Heterocrossa rubophaga是商业性悬钩子浆果作物和野生悬钩子物种的害虫。它的信息素最初被鉴定为单一成分，（7 Z）-nonadecen-11-one。在这里，我们报告了对该类胡萝卜素信息素的进一步调查，包括挥发物收集，腺体提取，质谱，微化学分析，电生理学和现场测试。从雌性腺体提取物中鉴定出烯烃（7 Z）-三甲苯，合成化合物从雄性蛾中产生触角反应。（7 Z）-三甲苯的现场测试表明，单独使用时没有吸引力，但与（7 Z）-nonadecen-11-一个，与单独的（7 Z）-nonadecen-11-one相比，它在所有测试剂量下的雄性蛾陷阱捕获量都增加了一倍以上。我们建议混合使用300 µg（7 Z）-壬二烯十一酮和300 µg（7 Z）-三甲苯，作为浆果种植者用于覆盆子蛾的改良监测工具。这是Z-链烯作为Carposinidae家族中信息素成分的第二份报告，迄今已鉴定出三种carposisnid信息素。
