Hermetic storage is used to protect grain against insect pests, but its utility is not limited to whole grains. We evaluated hermetically-sealed, polyethylene terephthalate (PET) bottles for preserving wheat and maize flour against red flour beetle (RFB, Tribolium castaneum, Herbst) population growth. Flours infested with RFB and kept in sealed PET bottles experienced much less weight loss over a three-month storage period than infested flour kept in unsealed bottles. RFB populations in wheat flour kept in sealed bottles did not increase, while populations in unsealed bottles grew about 50-fold during the same three-month period. Flour in sealed bottles had lower levels of oxygen and moisture than flour stored in unsealed bottles. Similar trends were observed for oxygen and moisture levels in maize flour held in hermetically sealed bottles. Hermetically-sealed bottles were effective in preventing RFB population growth and preserving maize and wheat flour. Farmers, consumers and food processors can safely store grain flour in hermetic sealed containers.
气密储存用于保护谷物免受虫害，但它的用途并不局限于整粒谷物。我们评估了用于保存小麦粉和玉米粉以防止赤拟谷盗（RFB，赤拟谷盗，赫布斯特）种群增长的气密聚乙烯 terephthalate（PET）瓶。与保存在未密封瓶中的受赤拟谷盗侵染的面粉相比，保存在密封PET瓶中的受侵染面粉在三个月的储存期内重量损失要少得多。保存在密封瓶中的小麦粉中的赤拟谷盗种群数量没有增加，而在未密封瓶中的种群数量在同一三个月期间增长了约50倍。密封瓶中的面粉比未密封瓶中储存的面粉具有更低的氧气和水分含量。对于保存在气密密封瓶中的玉米粉中的氧气和水分含量也观察到了类似趋势。气密密封瓶在防止赤拟谷盗种群增长和保存玉米粉和小麦粉方面是有效的。农民、消费者和食品加工商可以将谷物粉安全地储存在气密密封容器中。
