Climate warming significantly impacts soil temperature and moisture, leading to changes in the activity of soil mites and the foraging behaviour of edaphic predatory mites. The current research aimed to investigate the effect of temperature on the functional response of the predatory soil mite Blattisocius mali Oudemans preying on either eggs or males of the mould mite Tyrophagus putrescentiae Schrank. To analyze the functional response type, the generalized functional response equation of Real was used while the functional response parameters were determined using Roger, Hassell, and Cabello et al. models. Female adult B. mali displayed Type III and Type II functional responses when preying on eggs and males, respectively across all tested temperatures, ranging between 10 °C and 35 °C. The handling time of B. mali was shorter at higher temperatures, 25 °C, 30 °C, and 35 °C when preying on either eggs or males. In contrast, the potential for prey mortality, the attack rate, and the functional response ratio were higher at higher temperatures indicating higher efficiency of B. mali at higher temperatures. The temperature strongly impacted predators' efficiency, as accelerated predator action under warming increased prey consumption. However, functional response type did not change with warmer temperatures but varied with changing prey stages from egg to male.
气候变暖对土壤温度和湿度有显著影响，导致土壤螨类的活动以及土壤捕食性螨类的觅食行为发生变化。当前的研究旨在调查温度对捕食性土壤螨类巴氏钝绥螨（Blattisocius mali Oudemans）捕食腐食酪螨（Tyrophagus putrescentiae Schrank）的卵或雄螨时功能反应的影响。为了分析功能反应类型，使用了里尔（Real）的广义功能反应方程，同时使用罗杰（Roger）、哈塞尔（Hassell）和卡贝洛（Cabello）等人的模型来确定功能反应参数。在10℃至35℃的所有测试温度下，成年雌性巴氏钝绥螨在捕食卵和雄螨时分别表现出III型和II型功能反应。当捕食卵或雄螨时，巴氏钝绥螨在较高温度（25℃、30℃和35℃）下的处理时间较短。相比之下，较高温度下猎物的潜在死亡率、攻击率和功能反应率更高，表明巴氏钝绥螨在较高温度下效率更高。温度对捕食者的效率有强烈影响，因为变暖条件下捕食者行动加速，猎物消耗增加。然而，功能反应类型不会随着温度升高而改变，但会随着猎物从卵到雄螨的阶段变化而变化。
