Abstract Understanding movement of insects and their behavioral response in stored grain bulks helps in controlling their infestation. Studies have been conducted on insect movement; however, determination of patterns of insect distribution is quite difficult because their behavioral responses vary with species and life stages as well as with external stimuli under different storage conditions. This review discussed insect movement, movement detection and tracing methods. Different experimental setups used for determining insect movement were presented along with their advantages and limitations with special emphasis on factors influencing insect mobility. Various model equations to predict insect movement and their spatial distribution were stated. Further, practical difficulties and challenges associated with studies of insect movement under multiple gradients were discussed. Based on literature analysis, directions for future research were presented with respect to the requirement and applicability of the emerging cost-effective technologies for insect movement detection.

储粮环境下储粮昆虫的运动和行为反应——综述

摘要 了解昆虫在储存谷物中的运动及其行为反应有助于控制它们的侵扰。对昆虫运动进行了研究；然而，昆虫分布模式的确定非常困难，因为它们的行为反应因物种和生命阶段以及不同储存条件下的外部刺激而异。本综述讨论了昆虫运动、运动检测和追踪方法。介绍了用于确定昆虫运动的不同实验装置及其优点和局限性，并特别强调了影响昆虫运动的因素。陈述了预测昆虫运动及其空间分布的各种模型方程。更多，讨论了与多梯度下昆虫运动研究相关的实际困难和挑战。在文献分析的基础上，就昆虫运动检测的新兴成本效益技术的要求和适用性提出了未来研究的方向。
