The influence of temperature (17, 21, 25, 30 and 35 degrees C) on life-history traits of a Q-biotype Bemisia tabaci population on tomato is studied. Temperature-dependent relationships are characterized for immature developmental rate, immature survival, fecundity, longevity and intrinsic rate of increase. Development time vary from 20 days at 30 degrees C to 56 days at 17 degrees C and the lowest thermal threshold is estimated at 10.2 degrees C. The optimal temperature for immature development is 32.5 degrees C. Total fecundity (eggs per female) ranges from 105.3 (at 21 degrees C) to 41 (at 35 degrees C). The longevity decreases with temperature increase. The intrinsic rate of increase ranges from 0.0450 (at 17 degrees C) to 0.123 (at 30 degrees C). The functional relationships between temperature and life-history parameters are used to evaluate the effect of temperature on the population dynamics. Such mathematical relationships could provide a basis for future development of population models.
