Abstract

Temperature is a key factor that influences interactions among vector insects, viruses, and host plants. A deep understanding of how temperature affects the adaptability of aphids to virus-infected plants can provide valuable insights for improving control strategies against plant viral diseases. Herein, we evaluated the adaptability of the green peach aphid Myzus persicae to tobacco plants infected by Potato virus Y (PVY) across four temperatures using dual-choice bioassays, electropenetrography, and an age-stage, two-sex life table. The results revealed substantial differences in the adaptation of M. persicae to PVY-infected tobacco at different temperatures. The number of M. persicae selecting PVY-infected tobacco plants rapidly peaked as temperature increased, though an inverse trend occurred when temperatures surpassed 25 °C. At 30 °C, M. persicae showed reduced feeding ability, a considerably short duration of potential drop (pd) waves, and an increased pd frequency on PVY-infected plants. In addition, at 30 °C, M. persicae exhibited the shortest developmental duration, reduced total lifespan, and low fecundity, leading to negative population growth. This study aims to provide initial insights into how temperature stress affects M. persicae on PVY-infected plants, delivering useful information for disrupting vector-mediated transmission routes and controlling the spread of insect-borne viral diseases through targeted environmental interventions.

温度对桃蚜（半翅目：蚜科）对马铃薯病毒侵染烟草植株适应性的影响

温度是影响病媒昆虫、病毒和寄主植物相互作用的关键因素。深入了解温度如何影响蚜虫对病毒感染植物的适应性，可以为改进植物病毒性疾病的控制策略提供有价值的见解。本研究采用双选择生物测定法、电渗透法和年龄阶段、两性生命表，评估了桃蚜对马铃薯Y病毒（PVY）侵染烟草植株在4种温度下的适应性。结果表明，不同温度下桃蚜对pvy侵染烟草的适应性存在显著差异。桃蚜选择pvy侵染烟草植株的数量随着温度的升高迅速达到峰值，但当温度超过25℃时则呈相反趋势。在30℃条件下，桃蚜对pvy侵染植株的取食能力下降，潜在下降（pd）波持续时间明显缩短，pd频率增加。此外，在30℃条件下，桃蚜的发育期最短，总寿命缩短，繁殖力低，种群数量呈负增长。本研究旨在初步了解温度胁迫如何影响pvy感染植物上的桃蚜，为通过有针对性的环境干预破坏媒介介导的传播途径和控制虫媒病毒疾病的传播提供有用的信息。

期刊介绍： The Editors of Crop Protection especially welcome papers describing an interdisciplinary approach showing how different control strategies can be integrated into practical pest management programs, covering high and low input agricultural systems worldwide. Crop Protection particularly emphasizes the practical aspects of control in the field and for protected crops, and includes work which may lead in the near future to more effective control. The journal does not duplicate the many existing excellent biological science journals, which deal mainly with the more fundamental aspects of plant pathology, applied zoology and weed science. Crop Protection covers all practical aspects of pest, disease and weed control, including the following topics: -Abiotic damage- Agronomic control methods- Assessment of pest and disease damage- Molecular methods for the detection and assessment of pests and diseases- Biological control- Biorational pesticides- Control of animal pests of world crops- Control of diseases of crop plants caused by microorganisms- Control of weeds and integrated management- Economic considerations- Effects of plant growth regulators- Environmental benefits of reduced pesticide use- Environmental effects of pesticides- Epidemiology of pests and diseases in relation to control- GM Crops, and genetic engineering applications- Importance and control of postharvest crop losses- Integrated control- Interrelationships and compatibility among different control strategies- Invasive species as they relate to implications for crop protection- Pesticide application methods- Pest management- Phytobiomes for pest and disease control- Resistance management- Sampling and monitoring schemes for diseases, nematodes, pests and weeds.
