1. 蜜蜂Apis mellfera （L.）和小白Pieris rapae （L.）两种昆虫首次成虫出现。于1952年至2004年在西班牙进行了研究。从798个采样地点的广泛地理和地形范围中，在考虑了变异的结果后。采用多元回归模型检测物候变化的时间趋势。将春季温度作为解释变量，以检验气候对外观物候的影响，对最佳模型进行了重复。这两个物种表现出相似的时间趋势，将它们的外观物候推迟到20世纪70年代中期，并从那时开始提前。2月至4月间，两种植物的出现时间均与平均气温呈负相关，春季越温暖，两种植物出现时间越早。出现日期对温度的强烈依赖表明，气候波动是造成两种植物春季出现物候年际变化的主要原因，因此也解释了观测到的长期趋势。研究表明，昆虫物候是一种准确、灵敏的气候变化生物指标。
1. The first adult appearance of two insect species, the honey bee Apis mellfera (L.) and the small white Pieris rapae (L.). was examined between 1952 and 2004 in Spain.2. After factoring out the variability resulting, from the broad geographical and topographical range of the 798 sampling localities. multiple regression models were used to detect temporal trends in phenology.3. The best models were repeated, including spring temperature as the explanatory variable to examine the effects of climate on appearance phenology.4. Both species showed similar temporal trends, delaying their appearance phenology until the mid-1970s and advancing it since that time.5. The appearance times for both species were negatively related to mean temperature between February and April, with both species appearing earlier in years with warmer springs.6. The strong dependence of appearance dates on temperature indicates that climatic fluctuations are primarily responsible for the inter-annual variability in spring appearance phenology of both species, and consequently account for the observed long-term trends.7. This study demonstrates that insect phenology is an accurate and sensitive bioindicator of climate change.
