Abstract

BACKGROUND

The khapra beetle, Trogoderma granarium, is a serious pest of stored grains that infests more than 100 different commodities. The current wall trap used for monitoring is optimized for the behavior of khapra beetles. In this study, we tested existing and modified trap designs for Trogoderma after release of T. granarium exclusively. The work aimed to evaluate trap efficacy, while providing a template for further attract-and-kill research. Three bioassays were conducted in nine rooms. Four traps were evaluated: dome, wall, modified wall, and the Wilkins interception trap.

RESULTS

Based on our results, dome traps collected significantly more individuals compared to the other traps, whereas the modified wall and Wilkins traps collected significantly fewer individuals compared to the dome trap. Regarding progeny production, the highest number of individuals was found from a release distance of 0.1 m. The highest number of individuals was captured at 0.1 m.

CONCLUSIONS

The most effective trap was the dome trap. The plume reach and distance from the trap/attractant source is an important parameter that can affect trapping efficacy in monitoring programs. © 2025 The Author(s).

半化学诱捕器捕集粮食巨蛾的效果及羽流范围的估算

卡普拉甲虫（Trogoderma granarium）是储存谷物中的一种严重害虫，它会侵害100多种不同的商品。目前用于监测的壁式捕集器对卡布拉甲虫的行为进行了优化。在这项研究中，我们测试了现有的和改进的陷阱设计，专门用于释放大鼠后的Trogoderma。这项工作旨在评估陷阱的功效，同时为进一步的吸引和杀死研究提供模板。在9个房间进行了3次生物测定。评估了四种捕集器：圆顶捕集器、壁式捕集器、改良壁式捕集器和威尔金斯拦截捕集器。
