| 摘 要： | 研究种内竞争对桔小实蝇的个体大小、存活率、生物量及产卵量的影响,并进行了模拟分析。对影响种群动态的诸要素建立模糊集,用贴近度方法进行关键要素分析。在种内竞爭条件下,成虫产卵量是影响世代趋势指数的关键要素,蛹生物量是影响下代虫口密度的关键要素。

| Abstract: | This paper has studied the influence of intra-specific competition in B. dorsalis on sur-vival, biomass, individual size and oviposition, and done their simulation analysis. Key- factor analysis was conducted by means of fuzzy sets. Results shown that oviposition is the key -factor of generation increase index, pupal biomass is the key-factor of density of following generation. |
