Abstract Myzus persicae, Macrosiphum euphorbiae, Aphis gossypii and Aulacorthum solani (Homoptera: Aphididae) are principal pests of protected pepper crops in southeastern Spain. Our goal was to determine the incidence of aphids on pepper crops and the role of vegetation surrounding greenhouses as a source of aphids and their parasitoids. The population dynamics were followed in six commercial greenhouses during 3 years. Another 82 greenhouses and their surrounding vegetation were surveyed occasionally. Myzus persicae had the highest incidence in pepper greenhouses followed by M. euphorbiae and A. solani. Parasitism of all aphid species in greenhouses was low, Aphidius matricariae and Aphidius colemani being the most abundant parasitoids. Myzus persicae and Macrosiphum euphorbiae were the most abundant and polyphagous aphids, being present on 77 and 55% of the plants sampled outside greenhouses, respectively; species of Brassicaceae were the main hosts for both aphids. Aulacorthum solani was only present ...
