摘要

在恒温(20、24、28、32℃)和相对湿度(70 ~ 85%)条件下，研究了斐济叶螨在木瓜上的发育生物学和生命表特征。随着饲养温度条件的升高，斐济夜蛾生活期由34.46 d缩短至8.58 d。在20、24、28和32℃时，净繁殖率(R0)分别为23.48、39.06、33.75和23.48;种群内在增长率(rm)分别为0.0694、0.2003、0.2281和0.1902只/只/天。24 ~ 28℃是螨发育的最佳温度，28℃是螨繁殖的最佳温度。

Temperature dependent development and population performance of Tetranychus fijiensis Hirst (Acari: Tetranychidae) on Papaya

Developmental biology and life table characteristics of Tetranychus fijiensis Hirst (Acari: Tetranychidae) on papaya were studied at four distinct constant temperatures (20, 24, 28, and 32°C) and relative humidity (70-85%) conditions. With the increase in rearing temperature conditions, the length of T. fijiensis life cycle decreased from 34.46 to 8.58 days. At 20, 24, 28, and 32°C, the Net Reproduction Rate (R0) was 23.48, 39.06, 33.75, and 23.48 and; the intrinsic rate of population increase (rm) was 0.0694, 0.2003, 0.2281, and 0.1902 females/ female/day, respectively. The optimum temperature for mite development was observed to be between 24 and 28°C, while favourable temperature for optimal reproduction capacity of the mite was 28°C.
