Rate of hatching, pupation and adult emergence and fecundity were relatively high at 20°, 22.5°, 25° and 27.5°C and low at 17.5° and 30°C. No adult oviposited at 32.5°C. It was demonstrated that the multiplication of population was highest at 27.5°C, while very low at 30°C. In Japan, mean daily temperature during mid-summer seldom exceeds 27.5°C, and therefore, it is unlikely that the marked summer decline in diamondback moth population observed could be explained by the existence of a high temperature in this season. Rates of hatching, pupation and adult emergence were not affected by the level of humidity.
