【摘要】 本文依据已有的研究 ,通过探讨马铃薯甲虫Leptinotarsadecemlineata地理分布与各种生态因子之间的相互关系 ,阐述了马铃薯甲虫地理分布主要是由气候和寄主综合作用决定的 ,热量因子决定了该虫在纬度上的分布 ,寄主在其南界形成中起一定作用 ,而滞育是其适应气候和寄主季节性变化的最主要机制。更多还原

【Abstract】 Based on literature study,the relationship between the distribution of Colorado potato beetle,Leptinotarsa decemlineata,and ecological factors was studied.The study showed that distribution of Colorado potato beetle is mainly determined by climatic factor and host plants.Heat factors plays an important role in its distribution in latitude and host plant related to its distribution in low latitude.Colorado potato beetle adapted the season change of climate and host plant by diapause mechanism.更多还原
