Description

The longevity and body weight at each developmental stage of Glossina morsitans morsitans were examined under the following conditions : temperature 25±1℃, relative humidity 60±10% and photoperiod 12hr light and 12hr dark. The length of life of male adults (n=93) was 145.9±51.4 days, (m±SD) range 9 to 241 days, and that of female adults (n=73) was 131.1±58.3,range 4 to 208 days. The respective mean body weight was : 1-day-old male pupae, 28.8mg; 3-weeks-old male pupae, 25.1mg; 1-day-old male adults, 20.4mg. The equivalent weights of females were 29.9,26.3 and 22.0mg, respectively. The coefficient of correlation between the body weight of 1-day-old adults and their longevity was 0.005 for males and 0.025 for females, indicating that there was almost no correlation between longevity and body weight.
