摘要
研究了侧多食跗线螨［Ｐｏｌｙｐｈａｇｏｔａｒｓｏｎｅｍｕｓｌａｔｕｓ（Ｂａｎｋｓ）］在取食茄子条件下实验种群生命表，结果表明：该螨的内禀增长率ｒｍ＝０．２５８４，周限增长率λ＝１．２９４９，净增殖率Ｒ０＝１９．３９５３，种群世代平均周期Ｔ＝１１．４７２８ｄ，种群加倍时间ｔ＝２．６８２０ｄ。
The laboratory population life time of the Yellow mite, Polyphagotarsonemus latus (Banks) in feeding on eggplant was studied. The results showed that intrinisic rate of increase (r m), finite rate increase (λ), net reproduction rate (R 0), mean genenation time (T), and double population time (t) were 0.258 4, 1.294 9, 19.395 3, 11.472 8 d and 2.682 0 d separately.
