Tribolium castaneum is one of the most economically important insects that damages stored products. The effects of several infested or uninfested raw feed materials (wheat bran, coarse wheat meal, corn feed flour), feed products (compound feed for pigs and for laying hens) and flour mixed with brewer's yeast on the food-searching behaviour of T. castaneum adults were studied in a total of 48 combinations. Preference and olfactometer tests revealed that all the tested uninfested and intraspecific infested substrates were significantly more attractive to T. castaneum than the control (represented by part of an arena or olfactometer arm without substrate). We determined that all infested substrates were 2-9 times more attractive than uninfested in the preference test, while in the olfactometer test, they were 3-8 times more attractive. In comparing the attractiveness of the infested and uninfested substrates, in both tests wheat bran was found to be the most attractive substrate to T. castaneum adults and coarse wheat meal the least. The results of the present study contribute to our knowledge of how raw feed materials and products influence the behaviour of T. castaneum and their susceptibility to infestation, and indicate the possible utilization of wheat bran in monitoring processes of T. castaneum in pest management programmes.
赤拟谷盗是对储存产品造成损害的最重要经济昆虫之一。研究了几种受侵染或未受侵染的原料（麦麸、粗麦粉、玉米饲料粉）、饲料产品（猪用和蛋鸡用复合饲料）以及与啤酒酵母混合的面粉对赤拟谷盗成虫觅食行为的影响，总共设置了48种组合。偏好试验和嗅觉测定试验表明，所有测试的未受侵染和种内受侵染的基质对赤拟谷盗的吸引力均显著高于对照（以无基质的试验场部分或嗅觉测定仪臂表示）。我们确定，在偏好试验中，所有受侵染的基质比未受侵染的基质吸引力高2至9倍，而在嗅觉测定试验中，它们的吸引力高3至8倍。在比较受侵染和未受侵染基质的吸引力时，在两项试验中均发现麦麸是对赤拟谷盗成虫最具吸引力的基质，而粗麦粉最不具吸引力。本研究结果有助于我们了解原料和产品如何影响赤拟谷盗的行为及其受侵染的易感性，并表明麦麸在害虫管理计划中赤拟谷盗监测过程中的可能用途。
