Abstract

Disease dynamics are significantly influenced by insect vectors through their interactions with viruses and host plants. The objective of this study is to understand how increased temperatures affect virus transmission, providing insights critical for developing climate-resilient pest and disease management strategies. We investigated the effects of temperature on the survival and growth of Myzus persicae (Sulzer) (Hemiptera: Aphididae), a key vector of the cucumber mosaic virus (CMV). Experiments were conducted to assess aphid survival, reproduction, and intrinsic rate of increase on healthy and CMV-infected Nicotiana tabacum plants at 25℃ and 30℃. It was observed that higher temperatures did not negatively affect aphid survival. CMV transmission assay was performed by allowing aphids to acquire and inoculate the virus under varied temperature combinations, while the aphid feeding behavior was monitored at different temperatures. The transmission efficiency was markedly reduced at 30℃ compared to 25℃, regardless of variations in temperature during virus acquisition and inoculation. Analysis of probing behavior revealed that aphids' probing behavior differed at 30℃, likely contributing to reduced transmission efficiency at higher temperatures. These findings demonstrate the intricate interplay between temperature, vector behavior, and virus transmission. Together, this study emphasizes the importance of incorporating environmental temperature dynamics into the development of sustainable and climate-resilient strategies for managing vector-borne diseases in agriculture.

高温可通过改变黄瓜花叶病毒在烟草中的传播媒介的特性来减少黄瓜花叶病毒在烟草中的传播。
昆虫媒介通过与病毒和寄主植物的相互作用,显著影响疾病动态。这项研究的目的是了解温度升高如何影响病毒传播,为制定气候适应型病虫害管理策略提供至关重要的见解。研究了温度对黄瓜花叶病毒(CMV)关键载体桃蚜(Myzus persicae (Sulzer),半翅目:蚜科)存活和生长的影响。在25℃和30℃条件下,对健康和cmv感染的烟草植株上蚜虫的存活、繁殖和内在增长率进行了研究。观察到较高的温度对蚜虫的存活率没有负面影响。通过不同温度组合下蚜虫获取和接种CMV病毒进行CMV传播试验,同时监测不同温度下蚜虫的摄食行为。与25℃相比,无论病毒获取和接种过程中的温度变化如何,30℃下的传播效率都明显降低。分析发现,30℃时蚜虫的探测行为不同,这可能是高温下传播效率降低的原因。这些发现证明了温度、媒介行为和病毒传播之间复杂的相互作用。总之,本研究强调了将环境温度动态纳入可持续和气候适应型战略的重要性,以管理农业媒介传播疾病。
