| 摘 要： | 研究了种内竞争对瓜实蝇（Ｂａｃｔｒｏｃｅｒａｃｕｃｕｒｂｉｔａｅ）和南瓜实蝇（Ｂｔａｕ）的生长、发育及存活的影响．对不同竞争强度下蛹的生物量、成虫生物量、幼虫存活率、蛹存活率、蛹的大小和成虫大小进行拟合分析，其模拟方程各不相同，但模拟方程的微分形式可用一通式来表示：ｄｙ／ｄｘ＝ｋ（ｘ－ｘ０）ｘｉｙｊ（ｋ，ｘ０，ｉ，ｊ为常数）种内竞争对昆虫性比的影响不具规律性

| Abstract: | This paper deals with the influence of intraspecific competition in Bacterocera cucurbitae and B tau on population growth, development and survival.Pupal biomass, adult biomass,larval survival rate,pupal survival rate,pupal size and adult size are simulated in relation to different intensities of competition. The simulation equations of different indexes are different, but the differential forms of simulation equations can be expressed by the following formula:d y /d x=k(x-x 0)x iy j(k,x 0,i,j are constants).No regular events are observed for two flies indicating the intraspecific competitions influence on sexual ratio. |
