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.

夏威夷坚果中掠食性甲虫 Cathartusquadricollis（鞘翅目：森林科）对引诱剂的昼夜飞行活动

Catartus Quadricollis (Guerin-Meneville)（鞘翅目：Silvanidae）的昼夜飞行活动是夏威夷两种重要害虫的捕食者：咖啡浆果小蠹、Hypothenemus hampei (Ferrari) 和热带坚果螟、Hypothenemus obscurus (F.)（鞘翅目：在澳洲坚果果园中使用黄色粘虫诱捕器对象甲科（Scolytinae）进行了研究，其中黄色粘虫诱饵采用信息素和真菌挥发性引诱剂。这项研究是在一年中的不同月份和月球周期的不同时间（新月和满月）进行的。飞行活动在光相后期到暗相早期达到高峰，即 1830 至 2000 小时之间；凌晨 0700 点至 1030 点之间也有飞行活动，但程度较轻。飞行活动期间捕获的四颈毛虫数量与风速呈负相关。讨论了这些发现对制定最佳害虫管理策略（包括生物防治）的影响。
