中文摘要： 气候变暖影响了昆虫种群的发育速度、繁殖能力、时空分布动态和取食危害后果。多数入侵昆虫由于具有明显的生理或生态优势, 因而更易适应环境变化带来的选择压力, 导致其在气候变暖背景下, 种群入侵格局和生活史性状发生了新的转变, 引起相应的防治对策须待更新或调整。因此，研究气候变暖对入侵昆虫种群生态学影响具有重要的科学意义和应用价值。本项目拟以新近入侵我国城市生态系统的外来害虫悬铃木方翅网蝽为研究对象, 应用昆虫种群生态学、全球变化生态学、入侵生物学等原理和方法, 围绕气候变暖对悬铃木方翅网蝽种群的生长发育和繁殖等生物学性状影响这一关键科学问题,研究不同升温情景下该虫的生长发育和繁殖能力动态、宿主植物与昆虫对气候变暖物候响应差异及其后果等两个核心内容。从而为该入侵种的种群动态预测和治理提供科学依据, 为研究入侵昆虫对气候变化的响应规律提供基础资料。

英文摘要： Climate warming significantly affects insect's development, dynamics, distribution and damages. Providing with obviously physiological and/or ecological advantages, most invasive insect species are easier to adapt to the environment change pressure in the face of climate warming. As a consequence, the invasive population has been shifting both on biology and ecology, which causes the corresponding control methods to be updated or adjusted. Therefore, study on effect of climate warming on population of an invasive insect species has been emerging as a hot topic both on science and application. The present project will focus on a key scientific issues that concerns the effects of climate warming on the population development and history of an urban invasive insect species，the sycamore lace bug, Corythucha ciliata. This pest is a new invasive pest that was native to temperate regions and now invades widely in subtropical China and feeds on Platanus trees seriously in China. Appling the theories and methods from population ecology, global change ecology and invasive biology, we are intended to study on shifts of the occurrence, development and fecundity of the bugs in response to rising temperatures under climate warming. According to these studies, we want to further analyze and forecast the future population trend
