Abstract : The population growth of Cybister confusus, an aquatic insect in a pond was studied with emphasis on water temperature. Population of the Cybister confusus was examined in relation to degree-days. This measure accounts for time and the minimum temperature necessary for insect growth and reproduction to enhance population size. Result showed highest population density at about 17.6°C temperature. Studies demonstrated that the population of insects is directly proportional to change in seasonal temperature cycle.
