Effects of Temperature on Development and Reproduction of Thrips hamaiiensis (Morgan)
Abstract: To research the influence of temperature on the development and reproduction of Thrips hamaiiensis (Morgan), series of experiments were carried out to investigate the experimental population growth of T. Hamaiiensis at 5 constant temperatures (20℃, 24℃, 28℃, 32℃ and 36℃) in the laboratory. The results indicated that, within the range from 20℃ to 28℃, the developmental duration of T. Hamaiiensis evidently reduced with the increase of temperature, while increased when the temperature went beyond 3℃; within the range from 20℃ to 36℃. The developmental rate of T. Hamaiiensis increased with the increasing temperature. The development threshold temperature of T. Hamaiiensis at its egg, nymphal, prepupal, pupal and egg-adult stages was 15.67℃:, 9.48℃,, 11.06℃, 8.54℃ and 11.39℃, respectively, and the effective accumulated temperatures was 91.23, 82.35, 41.23, 34.81, 251.43℃ · d, respectively. Within the range of 20-36℃, the generation survival rate of T. Hamaiiensis decreased according to the sequence of 32℃, 28℃, 24℃, 20℃ and 36℃ It can be concluded that the temperature had great influence on the developmental duration and survivalrate of experimental populations of T. Hamaiiensis.
