Pheromone-baited traps are commonly used to monitor and detect moths. Traps and lures are often compared to each other to identify the optimum set up and lure dosage. However, it is also important to understand the efficiency of a trap in capturing the moths that are attracted to it. In the present study, three pheromone-baited traps were placed at the edge of a cornfield to determine the one with the highest capture rate of (Lepidoptera: Noctuidae): Scentry Heliothis traps, clear Unitraps, and green Unitraps. Once it was determined that green Unitraps captured more , field observations determined the number of moths captured in the traps compared to the number approaching, i.e., trap efficiency. Green Unitraps had a capture efficiency ranged from 5 to 11%, with an average of 11%. Unitraps, although useful for monitoring existing populations, may not be effective in detecting an invasive incursion. The implications of low capture efficiency in the surveillance of are considered, including possible explanations and next steps to improve monitoring efforts of heliothine moths.
性诱捕器通常用于监测和检测蛾类。诱捕器和诱芯常常相互比较,以确定最佳设置和诱芯剂量。然而,了解诱捕器捕捉被其吸引的蛾类的效率也很重要。在本研究中,在玉米田边缘放置了三个性诱捕器,以确定对(鳞翅目:夜蛾科)捕获率最高的诱捕器:Scentry棉铃虫诱捕器、透明Unitrap诱捕器和绿色Unitrap诱捕器。一旦确定绿色Unitrap诱捕器捕获了更多的[具体蛾类名称未给出],实地观察确定了诱捕器中捕获的蛾类数量与接近诱捕器的蛾类数量之比,即诱捕器效率。绿色Unitrap诱捕器的捕获效率在5%至11%之间,平均为11%。Unitrap诱捕器虽然有助于监测现有种群,但在检测入侵性虫口方面可能无效。本文考虑了在监测[具体蛾类名称未给出]时捕获效率低的影响,包括可能的解释以及改进棉铃虫蛾监测工作的后续步骤。
