Abstract: The relationship between the temperature and developmental period was investigated in an egg parasitoid, Trissolcus japonicus (Ashmead) (Hymenoptera: Scelionidae), reared on eggs of the fruit-piercing stink bug Glaucias subpunctatus (Walker) (Hemiptera: Pentatomidae). Adults of Tr. japonicus steadily emerged under 22, 25, 28, and 31°C conditions, and their normal development was affected under 18 and 34°C conditions. From these results, the developmental zero temperatures for females and males were estimated to be 12.43 and 11.65 °C, respectively. The calculated effective cumulative temperatures in females and males were 153.85 and 140.85 degree-days, respectively. Females fully matured in 3 days after emergence, and could lay 80.4 eggs throughout their lifetime. Based on these results, the relationship between the life histories of this parasitoid and G. subpunctatus was discussed.
