昆虫天敌攻击的结果通常受到宿主体内防御性微生物共生体的影响。热环境是已知影响昆虫共生体介导性状的因素。例如，较低的温度已被证明会降低果蝇中螺原体介导的保护作用。我们对保护性共生的理解需要更深入地理解环境-共生体-保护的联系。在这里，我们通过检查黄蜂攻击前、中、后的温度对苍蝇存活和黄蜂成功的影响，剖析了热环境对螺原体介导的对果蝇中Leptopilina boulardiin的保护作用的影响。我们观察到，发育温度的母亲的攻击幼虫，而不是温度的攻击幼虫本身期间或之后的黄蜂攻击，强烈地决定了螺原体的保护作用。较冷的母体环境与较弱的螺原体保护其后代。发育温度对螺原体介导的保护作用的影响可能是由螺原体滴度的降低介导的。这些结果表明，历史热环境是一个更强的决定因素比目前的环境保护。此外，保护是一种跨代非遗传变异的特征，可能会对选择产生复杂的短期反应。此外，thepiroplasma-Drosophilasymbioses的冷敏感性与更常见的在高温下共生失败形成对比，表明需要了解这种共生的低温敏感性的机制基础。
The outcome of natural enemy attack in insects is commonly impacted by the presence of defensive microbial symbionts residing within the host. The thermal environment is a factor known to affect symbiont‐mediated traits in insects. Lower temperatures, for instance, have been shown to reduceSpiroplasma‐mediated protection inDrosophila. Our understanding of protective symbiosis requires a deeper understanding of environment–symbiont–protection links. Here, we dissect the effect of the thermal environment onSpiroplasma‐mediated protection againstLeptopilina boulardiinDrosophila melanogasterby examining the effect of temperature before, during and after wasp attack on fly survival and wasp success. We observed that the developmental temperature of the mothers of attacked larvae, but not the temperature of the attacked larvae themselves during or after wasp attack, strongly determines the protective influence ofSpiroplasma. Cooler maternal environments were associated with weakerSpiroplasmaprotection of their progeny. The effect of developmental temperature onSpiroplasma‐mediated protection is probably mediated by a reduction inSpiroplasmatitre. These results indicate that historical thermal environment is a stronger determinant of protection than current environment. Furthermore, protection is a character with transgenerational nongenetic variation probably to produce complex short‐term responses to selection. In addition, the cool sensitivity of theSpiroplasma–Drosophilasymbioses contrasts with the more common failure of symbioses at elevated temperatures, indicating a need to understand the mechanistic basis of low temperature sensitivity on this symbiosis.
