| 摘 要： | 通过对新疆苜蓿叶象甲第1代自然种群数量动态规律的研究，组建了自然种群生命表，存活曲线属于PriceA型，曲线显示种群数量减少最大的阶段是生命早期卵至二龄期。决定因子Leroux r^2分析法表明，三龄期的大风、四龄被寄生、蛹期和二龄的感病是影响种群年度间数量变动的关键因子。种群的内禀增殖力为0．15，周限增长率为1．15，趋势控制指数IPC为11．92．单
雌平均产卵量307．56粒，经过一个世代种群的净增殖力为4．75。Leslie转移矩阵预测第二代成虫数量将是第一代的3．68～5．00倍。

| Abstract: | The magnitude of alfalfa weevil population in Xinjiang was researched,natural population life table was made.Price analysis of the survey curve showed that the magnitude of alfalfa weevil population was decreased in forepart stage,from egg to second stage.LeRoux r~2 analysis sowed that the magnitude dynamic of alfalfa weevil population was determined by big wind of third instar,larval parasitism of fourth instar,fungal infection of second instar etc.alfalfa weevil longevity averaged was 10.26 week.Englacial rate of increase was 0.15,finite rate of increase was 1.15,IPC(index population control)was 11.92.The each adult female produces 307.56 granular eggs.The life cycle was completed,however,the magnitude of alfalfa weevil population were rose for 4.75.Leslie transfer-matrix forecasted that the adults number of second generation rose by 3.68-5.00 times. |
