Insect populations were studied within two commercial peanut shelling facilities located in the southeastern United States. Commercially available pheromone/kairomone-baited dome traps and pheromone-baited flight traps were deployed throughout processing and shipping portions of the shelling plants and serviced weekly over one year. spp., and were the most common captures across locations. made up 87% and 88% of all captures in dome traps in plants one and two, respectively. While was not captured during the winter months in flight traps, it was captured with near 100% frequency in dome traps, suggesting that populations persisted throughout the year inside the facilities. populations were active year round. Across insect species and trap type, temperature was a significant covariate for explaining variation in insect counts. After accounting for the effect of temperature, there were always more insects captured in the processing portions of the facilities compared to the shipping areas. A negative linear relationship was observed between captures of and and trap distance from in-shell peanuts entering the shelling facilities. Conversely, fungivores were more evenly distributed throughout all parts of the shelling plants. These data suggest that management efforts should be focused where in-shell peanuts enter to reduce breeding and harborage sites for grain feeding insects.
在美国东南部的两个商业花生脱壳设施内对昆虫种群进行了研究。在脱壳工厂的加工和运输区域部署了市售的信息素/异种信息素诱饵穹顶诱捕器和信息素诱饵飞行诱捕器，并在一年多的时间里每周进行维护。 spp.和 是各地最常见的捕获对象。在工厂一和工厂二的穹顶诱捕器捕获的所有昆虫中， 分别占87%和88%。虽然 在冬季飞行诱捕器中未被捕获，但在穹顶诱捕器中的捕获频率接近100%，这表明该设施内的种群全年都存在。 种群全年都很活跃。在昆虫种类和诱捕器类型方面，温度是解释昆虫数量变化的一个重要协变量。在考虑温度的影响后，与运输区域相比，设施加工区域捕获的昆虫总是更多。在 与 的捕获量和诱捕器与进入脱壳设施的带壳花生的距离之间观察到负线性关系。相反，食真菌动物在脱壳工厂的所有区域分布更为均匀。这些数据表明，管理工作应集中在带壳花生进入的地方，以减少谷物取食昆虫的繁殖和栖息场所。
