Stored product insect pests seriously damage global food production, especially in developing countries. Chemical methods to control these pests are either becoming regulated due to health concerns or environmental damage or have become less effective as resistance evolves. New methods of pest management are therefore urgently sought. Thermal control is being increasingly used, when 60oC temperatures are applied to kill insects in contained facilities. However, this can be energetically expensive and cause collateral damage. The project will examine how less extreme temperatures can be used to control key pests through thermal sensitivities within reproduction, enabling more economically effective management. Lab experiments will be used to study how different thermal regimes with different insect populations influence reproduction, recovery, survival and potential to infest in some key stored product pests, scaling findings up to larger storage facilities.

仓储产品害虫严重损害全球粮食生产，特别是在发展中国家。控制这些害虫的化学方法要么由于健康问题或环境破坏而受到监管，要么随着耐药性的发展而变得不那么有效。因此迫切需要寻找新的害虫管理方法。热控制的使用越来越多，在封闭设施中采用 60°C 的温度来杀死昆虫。然而，这可能会耗费大量能源并造成附带损害。该项目将研究如何利用较低的极端温度通过繁殖过程中的热敏感性来控制主要害虫，从而实现更经济有效的管理。实验室实验将用于研究不同昆虫种群的不同热状况如何影响某些关键储存产品害虫的繁殖、恢复、生存和感染潜力，并将研究结果扩展到更大的储存设施。
