This study aims to determine the effects of temperature on the growth, development and reproduction of T. v. gigantina, and thereby to provide a foundation for the forecasting and scientific management of this pest. 【Methods】 Under a series of temperature gradients (19, 22, 25, 28 and 31℃), the developmental duration, food consumption, mating rate, oviposition, longevity of T. v.gigantina was investigated. 【Results】 Within the constant temperature ranging from 19 to 31℃, the duration of various developmental stages of T. v.gigantina shortened as temperature rose gradually. The development threshold temperatures of egg, larva, pupa, pre-oviposition and one complete generation were 9.24±0.45, 10.85±0.87, 14.56±0.85, 9.65±0.54, 10.48±0.52℃ and 341.22±9.54℃, respectively, and their effective accumulated temperatures were 1 285.64±17.65, 445.35±8.65, 13.34±1.25, 2 085.35±25.84 degree·days, respectively. The food consumption and mating rate were not affected significantly by temperature, and the number of eggs laid under temperatures of 22, 25 and 28℃ was higher than that under the other temperatures. The adult longevity was negatively correlated with temperature. 【Conclusion】 The temperature range of 22-28℃ is the most suitable for the growth, development and reproduction of T. v. gigantina. These findings provide valuable information for rational control of T. v. gigantina.
