The temporal and spatial patterns in flight activity outside of a rice mill were evaluated for the lesser grain borer [Rhyzopertha dominica (F.)], warehouse beetle [Trogoderma variabile Ballion], cigarette beetle [Lasioderma serricorne (F.)], and Indian meal moth [Plodia interpunctella (Hüϋbner)] to determine critical times of year when the mill would be vulnerable to invasion. Insect activity was monitored using pheromone-baited glue traps (N = 99) from June 2008 to October 2010. Traps were placed along exterior walls of all major buildings and along the fence around the perimeter of the facility. Trogoderma variabile was the most abundant species, with flight activity between mid-March and November. No activity of T. variabile was observed during December through March. Rhyzopertha dominica was also abundant, with activity in mid-April through October. A few adult R. dominica were captured in traps during winter months in the first year of study. Trap captures for all four species increased with an increase in temperature and can be described by linear equations. Knowing seasonal patterns in insect activity allows rice facilities to better understand when facilities are most vulnerable to pest activity. However, this study demonstrates that more research is needed to address how insects are immigrating and emigrating within and around a rice mill.
对谷蠹[谷斑皮蠹（Rhyzopertha dominica (F.)）]、仓库甲虫[赤拟谷盗（Trogoderma variabile Ballion）]、烟草甲[烟草甲（Lasioderma serricorne (F.)）]和印度谷螟[印度谷螟（Plodia interpunctella (Hübner)）]在碾米厂外飞行活动的时空模式进行了评估，以确定该厂一年中易受害虫入侵的关键时期。2008年6月至2010年10月，使用诱捕信息素的粘虫板（N = 99）监测昆虫活动。诱捕器放置在所有主要建筑物的外墙以及设施周边的围栏沿线。赤拟谷盗是数量最多的物种，飞行活动时间为3月中旬至11月。12月至次年3月未观察到赤拟谷盗的活动。谷蠹数量也较多，活动时间为4月中旬至10月。在研究的第一年冬季，诱捕器捕获了少量谷蠹成虫。所有四种物种的诱捕捕获量均随温度升高而增加，可用线性方程描述。了解昆虫活动的季节性模式有助于碾米厂更好地了解何时工厂最易受到害虫活动的影响。然而，本研究表明，需要更多研究来解决昆虫如何在碾米厂内部和周围迁入和迁出的问题。
