The diel flight activity in Cathartus quadricollis (Guerin-Meneville) (Coleoptera: Silvanidae), a predator of two important pests in Hawaii, coffee berry borer, Hypothenemus hampei (Ferrari) and tropical nut borer, Hypothenemus obscurus (F.) (Coleoptera: Curculionidae: Scolytinae) was studied in a macadamia nut orchard using yellow sticky traps baited with pheromone and fungal volatile attractants. The study was conducted at different months throughout the year and at different times during the lunar cycle (new moon and full moon). Flight activity peaked in the late hours of the photophase into the early hours of the scotophase, between 1830 and 2000 h; flight activity also occurred but to a lesser extent in the early morning hours between 0700 and 1030 h. Numbers of captured C. quadricollis during periods of flight activity were negatively correlated with wind speed. The implications of these findings for the development of optimal pest management strategies including biological control are discussed.
在夏威夷的一片澳洲坚果果园中,使用涂有性信息素和真菌挥发性引诱剂的黄色粘虫板,对四脊扁甲(Cathartus quadricollis)(Guerin-Meneville)(鞘翅目:锯谷盗科)的昼夜飞行活动进行了研究。四脊扁甲是夏威夷两种重要害虫——咖啡果小蠹(Hypothenemus hampei)(Ferrari)和热带坚果小蠹(Hypothenemus obscurus)(F.)(鞘翅目:象甲科:小蠹亚科)的捕食者。该研究在全年的不同月份以及月周期的不同时间(新月和满月)进行。飞行活动在光照期后期至暗期早期达到峰值,时间为18:30至20:00;清晨07:00至10:30也有飞行活动,但程度较轻。飞行活动期间捕获的四脊扁甲数量与风速呈负相关。本文讨论了这些发现对包括生物防治在内的最佳害虫管理策略制定的意义。
