Biological control of aphids (Hemiptera: Aphididae) is reviewed. A brief report on the history of biological control of aphids is given. Candidate natural enemies including parasitoids, predators and entomopathogens consisting of about 12 groups are listed. Brief information about viable multiplication technologies for important species in each group is provided. Finally biological control of aphids in open fields and in glasshouses by using different natural enemies is reviewed by analyzing different attempts made in India and elsewhere. It is concluded that parasitoids in general and aphidiids in particular possess greater potential than predators and entomopathogens both in open fields and in glasshouses.
