Abstract

The effects of temperature on the development duration and longevity of adult of Chelonus murakatae were studied under five constant temperatures including 22.5, 25, 27.5, 30 and 32.5 ± 0.5 °C under laboratory conditions. It was observed that the development time was inversely proportional to the temperature within the range of 22.5 to 32.5 °C. The results indicated that the optimum temperature for development ranged from 25 to 30 °C. Thermal threshold was estimated by a linear model which was recorded as 15.5 and 18.5 °C for males and females, respectively. Number of degree days required to complete the development from egg to adult were 439.6 degree days in males and 336.8 degree days in females. Adult longevity also decreased with increase in temperature. This information can be used for optimizing mass culturing and field release for an efficient biological control of Chilo suppressalis in this specie. [ABSTRACT FROM AUTHOR]
