To study the effect of host on biology of Chrysoperla carnea and predatory potential, investigate the optimum temperature regime, effect of cold storage and radiation to enhance the shelf-life. An artificial larval diet and for storage 7.5°C, 10°C and 12.5°C temperature showed successful results. Female preferred black colour cover for egg laying. Significant effects were recorded on progeny production from a sex ratio of 1:3 male female ratios. Nu lure was better among all the proteins tested, gave high rate of survival while larvae reared singly. Results showed that 26±2°C was optimum t...

Significant effects were recorded on progeny production from a sex ratio of 1:3 male female ratios. Nu lure was better among all the proteins tested, gave high rate of survival while larvae reared singly. Results showed that 26±2°C was optimum temperature for mass rearing. Proper diet and space play vital role in adult rearing, among others glass cages proved better. Laboratory reared green lacewings performed better as compared with field collected. Radiation of different doses and toxicity of insecticides investigated against all stages of C. carnea. Releases of egg cards in cotton field for population management of sucking insect pest of cotton. Whereas 3rd instar larvae were released for pest population reduction followed by second instar.
