    • Abstract

       

      The effect of temperature and humidity onAcrida exaltata Walk. has been studied to have two aspects in relation to (i) its effect on hopper development and (ii) its effects on the fertility-fecundity. The rate of development was affected by the moisture present in the environment. No development took place at 0%, 10% and 20% RH. Most desirable range of humidity was between 50–70% RH. Development took place at 20°, 30°, 35° and 40° C in 92·8, 74·8, 71·8 and 66·6 days in males and 101·0, 86·4, 85·6 and 75·2 days in females. Percentage of hoppers reaching the adult stage, longevity of adults, average number of copulation and average number of eggpods per female was influenced by the temperature.
