Climate change has far-reaching effects on food security and agriculture, affecting crop yields and food distribution. Agriculture relies heavily on water for irrigation and production, making it vulnerable to water scarcity. Additionally, climate change can affect crop pest insects, leading to increased global crop losses, particularly in cereals, an important component of the human diet. Aphids are major crop pests and have a symbiotic relationship with bacterial endosymbionts that can contribute to their success as pests under a climate change scenario. To test the effect of drought on aphids, we examined varying levels of water deficit and endosymbiont composition on the grain aphid (Sitobion avenae) performance on wheat under controlled laboratory conditions. We measured the intrinsic rate of population increase (r_m), the body weight of adult aphids, and the pre-reproductive period for different genotypes of the grain aphid (including Chilean superclones) under different irrigation regimes. We also analyzed the relative abundance of their endosymbionts under the different water treatments.

小麦缺水和蚜虫恢复力：在受控实验室条件下检查 Sitobion avenae F. 及其细菌共生体相互作用


气候变化对粮食安全和农业产生深远影响，影响农作物产量和粮食分配。农业严重依赖水进行灌溉和生产，因此容易受到缺水的影响。此外，气候变化会影响农作物害虫，导致全球农作物损失增加，尤其是谷物，这是人类饮食的重要组成部分。蚜虫是主要的农作物害虫，与细菌内共生体有共生关系，这有助于它们在气候变化情景下成为害虫的成功。为了测试干旱对蚜虫的影响，我们在受控实验室条件下检查了不同水平的水分亏缺和内共生体组成对小麦籽粒蚜虫 （Sitobion avenae） 性能的影响。我们测量了不同灌溉条件下不同基因型的谷物蚜虫（包括智利超级克隆）的内在种群增长率 （r_m）、成年蚜虫的体重和繁殖前期。我们还分析了不同水处理下它们的内共生体的相对丰度。
