Two values of thermal requirements, the lower developmental threshold (LDT), that is, the temperature at which development ceases, and the sum of effective temperatures, that is, day degrees above the LDT control the development of ectotherms and are used in phenology models to predict time at which the development of individual stages of a species will be completed. To assist in the rapid development of phenology models, we merged a previously published database of thermal requirements for insects, gathered by online search in CAB Abstracts, with independently collected data for insects and mites from original studies. The merged database comprises developmental times at various constant temperatures on 1,054 insect and mite species, many of them in several populations, mostly pests and their natural enemies, from all over the world. We show that closely related species share similar thermal requirements and therefore, for a species with unknown thermal requirements, the value of LDT and sum of effective temperatures of its most related species from the database can be used.
两种热需求值，下限发育温度（LDT），即发育停止的温度，以及有效温度总和，即 LDT 以上的日温度，控制着变温动物的发育，并用于物候模型来预测物种各发育阶段完成的时间。为了帮助快速开发物候模型，我们将之前通过 CAB Abstracts 在线搜索收集的昆虫热需求数据库与我们从原始研究中独立收集的昆虫和螨类数据合并。合并后的数据库包含了 1054 种昆虫和螨类在各种恒温下的发育时间，其中许多是来自世界各地的多个种群，主要是害虫及其天敌。我们表明，亲缘关系密切的物种具有相似的热需求，因此，对于一种未知热需求的物种，可以使用数据库中与其最相关的物种的 LDT 值和有效温度总和。
