| 为探明温度对长刺新小绥螨Neoseiulus longispinosus Evans捕食朱砂叶螨Tetranychus cinnabarinus Boisduval功能反应的影响，在温度15℃、18℃、21℃、24℃、27℃、30℃条件下，研究了长刺新小绥螨雌成螨对朱砂叶螨卵、幼螨、前若螨、后若螨、雌成螨的捕食情况。结果表明，在15~30℃范围内，随着温度升高、猎物密度增加，长刺新小绥螨对朱砂叶螨的捕食量呈上升趋势。同一温度及猎物密度时，长刺新小绥螨雌成螨对朱砂叶螨不同螨态的捕食量为由高到低为幼螨>前若螨>后若螨>卵>雌成螨。在15~30℃温度范围内，长刺新小绥螨对朱砂叶螨各螨态的捕食功能反应均符合Holling-Ⅱ型方程，以日均捕食量与捕食效能(a/Th)为捕食能力的评价指标，30℃时长刺新小绥螨对朱砂叶螨幼螨的捕食能力最强，为111.80头/d，15℃对朱砂叶螨雌成螨的捕食能力最弱，为4.98头/d；长刺新小绥螨对朱砂叶螨幼螨的寻找效应强于其他螨态，且随温度升高呈上升趋势。在30℃温度条件下长刺新小绥螨对朱砂叶螨幼螨及前若螨有较强的控害能力。 |

| The aim of this study was to examine the effects of temperature on the functional response exhibited by predatory mite, Neoseiulus longispinosus Evans, preying on Tetranychus cinnabarinus Boisduval. Predation efficiency of female adult of N. longispinosus on various life stages of T. cinnabarinus, including eggs, larvae, protonymphs, deutonymphs, and female adults were observed across temperatures ranging from 15°C to 30°C. The predation of N. longispinosus on T. cinnabarinus increased with elevating temperature and prey density. At equivalent temperature and density, the predation amounts of female adult of N. longispinosus on different stages of T. cinnabarinus from large to small were as follow: larvae > protonymphs > deutonymphs > eggs >female adults. The predation function response of N. longispinosus to each stage of the T. cinnabarinus followed the Holling-II equation within the 15~30°C temperature spectrum. Predation ability was evaluated by average daily predation and predation efficacy (a/Th). Notably, and the N. longispinosus exhibited the highest predation ability on the larvae of T. cinnabarinus at 30°C, reaching 111.80 individuals per day, whereas the weakest predation capability (4.98 individuals per day) was found when preying on the female adult of T. cinnabarinus at 15°C. The search efficiency of the N. longispinosus on T. cinnabarinus larvae was higher than that of other stage, increasing with elevating temperatures. At 30°C, N. longispinosus demonstrated a strong ability to control T. cinnabarinus larvae and protonymphs. |
