Hawthorn spider mite，Tetranychus viennensis Zacher, is an important and damaging pest in apple orchards worldwide and has become the most serious pest on apple in north China，where it is extremely hot during the summer, with maximum daily temperatures consistently above 35.0℃. In order to explore the influence of brief exposure to high temperature on the biology of mite, in this paper, a leaf disc bioassay was employed to investigate the effects of high temperature shocks on the bionomics of T. viennensis in the laboratory under the conditions of (25±1)℃, (60±7)% RH, and a photoperiod of 16h∶8h (Light∶Dark). This was done by determining the developmental durations of each life stage，adult longevity, fecundity, and hatchability of the spider mites after the eggs, larvae, protonymphs, deutonymphs, and newly emerged adults had been exposed to high temperature of 33℃, 36℃, 39℃, and 42℃ for 1—6 hours. The results indicated that high temperature shocks had significant effects on the fecundity and hatchability of the mite, and the effects depended on the temperature, the length of the exposed period and life stage exposed, but high temperature shocks had no effects on the longevity of female adults. Analysis showed that no significant effect was detected in the longevity of female adults survived the treatments of 33—42℃ with an exposure period of 1—6h, in spite of the exposed life stages of the mite. The hatchability remained the same as the control in all the treatments of eggs exposed to high temperature shocks, while hatchability decreased by 7.01% and 11.36% in female adults exposed to temperatures of 39℃ and 42℃ for 4—6 hours. The pre-imaginal development durations significantly prolonged in those derived from eggs exposed to 39℃ and 42℃ for 6 hours, and the fecundity of the females increased by 34.50% and 37.41%, respectively. Exposures of larvae to 39℃ and 42℃ temperature for 6 hours resulted in increased fecundity by 27.02% and 35.83% in the surviving females; however, no significant effect was found in both fecundity and hatchability in females derived from protonymphs exposed to the temperature of 39℃ and 42℃ for 4 and 6 hours. No significant effect was found in the capability of insemination and fertility in adult T. viennensis survived the treatments of 39℃ and 42℃ for 6 hours as teleiochrysalis and newly emerged adults. From the viewpoint of population, authors believe that an exposure of the mite to high temperature shocks would result in an increased population growth rate due to the high proportion of eggs in the natural population of the mite.
