Understanding the effects of temperature on the metabolic activity and the rate of depletion of energy reserves by Ixodes ricinus can represent an important contribution to explaining patterns of tick activity and the likely impacts of environmental change on tick and tick-borne disease risk. Here, a cohort of I. ricinus nymphs, males, and females was collected and placed into incubators at temperatures of between 5 and 30 °C. The protein, carbohydrate, total lipid, neutral lipid, and glycogen levels were measured for nymphs for up to 70 days and adults up to 42 days. In nymphs, at day 0, glycogen was the most abundant metabolite followed by carbohydrate, with relatively low concentrations of protein and lipids. For males, the concentrations of different metabolites were relatively similar. In contrast, for females, concentrations of glycogen and carbohydrate were relatively low compared to those of protein and neutral lipids. Significant exponential declines in metabolite concentrations of all metabolites were detected over time for all life-cycle stages and at all temperatures. Nymphs generally showed lower rates of resource depletion than adults at all temperatures. The lower thresholds for metabolic activity were estimated to be between −10 and −5 °C. The Q₁₀ values, which describe the thermal sensitivity of metabolic rate, were estimated to be relatively low (1.5 for nymphs, 1.71 for males, and 1.63 for females) compared to insects where they are typically around 2.5 (range: 1.5–3), and this is considered to be an adaptation to increase survival during the extended inter-feed intervals.

了解温度对on虫的代谢活动和能量储备消耗率的影响可能对解释of活动模式以及环境变化对tick和tick传播疾病风险的可能影响做出重要贡献。在这里，我是蓖麻收集若虫，雄性和雌性，并将其置于温度为5至30°C的培养箱中。对若虫（长达70天）和成虫（长达42天）的蛋白质，碳水化合物，总脂质，中性脂质和糖原水平进行了检测。在若虫中，在第0天，糖原是最丰富的代谢产物，其次是碳水化合物，蛋白质和脂质的浓度相对较低。对于男性，不同代谢物的浓度相对相似。相反，与蛋白质和中性脂质相比，女性的糖原和碳水化合物浓度相对较低。在所有生命周期阶段和所有温度下，随着时间的推移，所有代谢物的代谢物浓度均出现了显着的指数下降。若虫在所有温度下的资源耗竭率通常都低于成年人。代谢活性的下限估计在-10至-5°C之间。Q相对于昆虫（通常约为2.5）（范围：1.5–3），估计有_10个值描述了代谢率的热敏感性，这些值相对较低（若虫为1.5，雄性为1.71，雌性为1.63）。这被认为是在延长的喂饲间隔期间增加存活率的一种适应措施。
