Many studies have discussed the effects of climatic change caused by global warming on herbivorous invertebrate populations, but few studies have enough data on the relationship between insect and host plants in the field. This study tried to know the effects of climatic changes caused by human activities on food condition and population dynamics of insect population. Two climatic changes were treated, one was global warming and the other was acid rain. Relationship between phenology of maple trees and population dynamics of an aphid was analyzed and it was ascertained that phenology of host tree has a strong influence on insect population. Population dynamics of the insect can not understood well without the information of the phenology of the host tree. As winter chill determines the thermal sum to spring bud burst, global warming has a possibility to cause a strong adverse effect on bud burst phenology on maples and also on insects.Defoliation of pine moth decreased the amount of current needles of pine. But, acid rain increased the amount of needles. The two factors, defoliation and acid rain, had interactions.

许多研究讨论了全球变暖引起的气候变化对草食性无脊椎动物种群的影响，但很少有研究有足够的数据，昆虫和寄主植物之间的关系在外地。本研究试图了解人类活动引起的气候变化对昆虫种群食物条件和种群动态的影响。两个气候变化处理，一个是全球变暖，另一个是酸雨。分析了枫树物候期与蚜虫种群动态的关系，确定了寄主树木的物候期对蚜虫种群有很大的影响。没有寄主树木的物候信息，就不能很好地了解该虫的种群动态。由于冬季寒冷决定了春季萌芽的热量总和，全球变暖有可能对枫树和昆虫的萌芽物候造成强烈的不利影响。松蛾的落叶减少了松树的针叶数量。但是，酸雨增加了针的数量。落叶和酸雨这两个因子存在交互作用。
