Abstract

Abstract Observations of wild and colony-reared small hive beetle populations indicate that the beetles form aggregations of many individuals of both sexes. Volatile collections performed on males and females have identified a potential male-produced pheromone comprised of 6-methyl-5-hepten-2-one, nonanal, and decanal. Flight tunnel and laboratory trapping assays were conducted using a synthetic pheromone blend (i.e., 6-methyl-5-hepten-2-one, nonanal, and decanal) and a blend of fruit volatiles (i.e., ethanol, ethyl butyrate, acetic acid, ethyl acetate, and acetaldehyde). Results showed that the synthetic pheromone blend along with a fruit-derived attractant captured significantly more beetles than the control. The identification of a potential pheromone is an important step in the search to provide effective control and monitoring of the small hive beetle. Resumen Las observaciones de poblaciones de pequeños escarabajos de la colmena silvestre criados en colonias indican que los escarabajos forman agregaciones de muchos individuos de ambos sexos. Recolecciones volátiles realizadas sobre los machos y hembras han identificado una posible feromona producida por machos compuesta por 6-metil-5-hepten-2-ona, nonanal y decanal. Los ensayos de captura en laboratorio y en el túnel de vuelo se realizaron utilizando una mezcla de feromonas sintéticas (es decir, 6-metil-5-hepten-2-ona, nonanal y decanal) y de volátiles de frutas (etanol, butirato de etilo, ácido acético, acetato de etilo y acetaldehído). Los resultados mostraron que la mezcla de feromonas sintéticas junto con un atrayente derivado de frutas capturó significativamente más escarabajos que el control. La identificación de una feromona potencial es un paso importante en la búsqueda para proporcionar un control y seguimiento efectivos del pequeño escarabajo de la colmena.

一种潜在的诱杀毒蜥的信息素(鞘翅目:毒蜥科)
对野生和殖民地饲养的小型越冬甲虫种群的抽象观察表明,甲虫形成了许多男女个体的聚集。对男性和女性进行的挥发性收集发现了一种潜在的男性生产的pheromone,由6-甲基-5-庚-2-酮、壬醛和癸烷组成。飞行隧道和实验室陷阱测试是使用合成的pheromone混合物(即6-甲基-5-庚-2-酮、壬醛和癸烷)和挥发性水果混合物(即乙醇、丁酸乙酯、乙酸、乙酸乙酯和乙醛)进行的。结果表明,合成的pheromone与一种水果衍生的引诱剂混合,捕获的甲虫明显多于对照。确定潜在的外激素是寻找有效控制和监测小型蜂鸟的重要步骤。摘要对在殖民地饲养的小型野生蜂巢甲虫种群的观察表明,甲虫形成了许多两性个体的聚集。对雄性和雌性进行的挥发性收集确定了雄性产生的一种可能的信息素,由6-甲基-5-庚-2-酮、壬醛和癸醛组成。实验室和飞行隧道中的捕获试验是使用合成信息素(即6-甲基-5-庚烷-2-酮、壬醛和癸烷)和水果挥发性物质(乙醇、丁酸乙酯、乙酸、乙酸乙酯和乙醛)的混合物进行的。结果表明,合成信息素与水果源引诱剂的混合物捕获的甲虫明显多于对照。识别潜在的信息素是寻找有效控制和跟踪蜂巢中小型甲虫的重要一步。

期刊介绍: Florida Entomologist is the official journal of the Florida Entomological Society. Volumes 1-3 were published under the name The Florida Buggist. The Florida Entomological Society still produces the traditionally printed version of Florida Entomologist, but you can also view, search, or print any article published since June 1917 by accessing online files. Web access is made possible by the Society’s electronic publication project begun in 1993
