The book describe the role of aphids and their natural enemies on different varieties of cauliflower crop. Aphids are among the most destructive insect pests of cultivated crops that are widely distributed in Pakistan and throughout the world. Biological control is an essential component in integrated management of aphids. Variety selection and crop management practices are the main factors that contribute to growing profitable horticultural crops. Adjusting the planting date of row crops, thereby altering the production season, may be another viable method for reducing pesticide use. Interrelationship of aphids and their natural enemies on different varieties of cauliflower was studied during the research. It was found that aphid's populations were varied according to the planting dates of different varieties. Resistant and susceptible varieties of crop in relation to planting dates identified in this study. The population pattern of predator and parasitoid were found directly proportional to the aphids. The role predators and parasitoids to control pest population were examined in the light of this research.
