摘要

昆虫在收获后的商品中出没,造成重大损害或破坏,每年造成数十亿美元的产品损失。作为接触性杀虫剂的杀虫剂处理在控制昆虫种群方面是有效的。然而,如果有食物存在,接触这些杀虫剂后昆虫的恢复会增加,从而降低表面处理的效果并导致持续的虫害。此外,温度和湿度的变化可能在恢复过程中发挥重要作用。在这里,我们评估了食物、温度和湿度对接触杀虫剂后红粉甲虫恢复的作用。我们发现食物是在不同温度和湿度条件下恢复的重要因素。虽然在温暖的温度和较高的湿度下,恢复速度更快,但在有食物和没有食物的情况下,恢复速度进一步提高。此外,我们发现,任何数量的面粉,甚至是粉尘,都能导致90%以上的甲虫在杀虫剂暴露后恢复,但当沙子代替面粉时,与没有食物处理相比,回收率低25%。这些结果突出了环境因素和食物可得性如何影响杀虫剂治疗效果的重要性。食品设施的卫生至关重要,因为即使是最少量的食物也会导致大量的恢复,使甲虫能够逃离处理过的区域并在整个设施中移动。需要进一步的工作来确定不同种群和不同昆虫物种之间潜在恢复的差异,以了解局部适应潜力。

Impacts of food, temperature, and humidity on recovery in Tribolium castaneum (Coleoptera: Tenebrionidae) after exposure to a contact pyrethroid insecticide.

Insects that infest postharvest commodities cause significant damage or destruction, costing billions of dollars in lost products yearly. Insecticide treatments applied as contact insecticides are effective in managing insect populations. However, recovery of the insects after exposure to these insecticides is increased if food is present, reducing the efficacy of surface treatments and leading to continued infestations. In addition, variation in temperature and humidity could play a significant role in recovery. Here, we assess the role of food, temperature, and humidity on the recovery of Tribolium castaneum Herbst, red flour beetle, after exposure to a contact insecticide. We found food is an important factor in recovery under different temperature and humidity conditions. While recovery was higher at warmer temperatures and higher humidities, recovery increased further when food was present versus absent. Moreover, we found that any amount of flour, even a dusting, resulted in over 90% of beetles recovering after insecticide exposure, but when sand was substituted for flour, recovery was 25% lower compared to a no food treatment. These results highlight the importance of how environmental factors and the availability of food influence efficacy of insecticide treatments. Sanitation in food facilities is critically important as even the smallest amount of food present can cause substantial recovery, allowing beetles to escape treated areas and move throughout facilities. Further work pinpointing variation in underlying recovery between different populations and among different insect species is needed to understand local adaptation potential.

期刊介绍: The Journal of Insect Science was founded with support from the University of Arizona library in 2001 by Dr. Henry Hagedorn, who served as editor-in-chief until his death in January 2014. The Entomological Society of America was very pleased to add the Journal of Insect Science to its publishing portfolio in 2014. The fully open access journal publishes papers in all aspects of the biology of insects and other arthropods from the molecular to the ecological, and their agricultural and medical impact.
