Abstract:Red palm weevil (RPW), Rhynchophorus ferrugineus (Olivier), native to Southern Asia, is becoming a serious invasive pest of palms in China in recent years. To clarify the effect of temperature on the development of RPW, the developmental time, survival rate and fecundity of RPW reared on Canary Island date palm, Phoenix canariensis, were investigated and population parameters were calculated at five constant temperatures (19, 22, 26, 30 and 33℃) in the laboratory. The result showed that the developmental time decreased with temperature increasing from 19℃ to 30℃. The developmental time for the whole generation at 19, 22, 26, 30℃ was 214.9, 141.4, 74.1, 63.2 days, respectively. The developmental threshold temperature and effective accumulative temperatures required for the whole generation were 14.2℃ and 1067.7 degree-days, respectively. Longevity of adult RPW was shortened with temperature increasing from 22℃ to 33℃. Generally, the longevity of male RPW was longer than that of female. The maximum number of eggs laid per female was 267.8 at 26℃, while the minimum was 30.5℃ at 19℃. The most suitable temperature range for the development of RPW was from 26℃ to 30℃, and the oviposition and population intrinsic rate of natural increase (rm) at this condition were higher than that at other temperatures.
