Abstract
The development, survival and life table parameters of the tenuipalpid mite, Phyllotetranychus gawadii Halawa, Mesbah & Mohamed fed on date palm, Phoenix dactylifera L. leaves were determined at 25 and 30±2° C and 65±5%R.H. in laboratory. The data showed that female and male had three nymphal stages before reaching adulthood. The tritonymphal stage was recorded for the first time. The shortest periods of the incubation period, immature stages and longevity were (13.23, 36.83, 65.58) days and (12.18, 25.03, 48.40) days for female and male, respectively, at 30ºC. The temperature 30 ºC enhanced the maximum value of intrinsic rate of increase (rm) 0.0629 individuals / ♀ / day, and maximum net reproductive rate (R0) 44.01 individuals / generation. Maximum fecundity was obtained at 30ºC after 64.87 days as 3.86 eggs / ♀ / day. The mean generation time (T) and generation doubling time (DT) values had affected by temperature.
