Nutritive cost of intraguild predation on eggs of Coccinella septempunctata and Adalia bipunctata (Coleoptera: Coccinellidae)

Lady beetles (Coleoptera: Coccinellidae) as a biological control agent are a group of beetles with a considerable diversity and adaptation in different habitats. Among aphids, Aphis punicae Passerini (Hemiptera: Aphididae) is one of the most important pests of pomegranate orchards in Iran. This pest reduces plant vigor, facilitate the growth of mold on leaves, and consequently influences crop quality and yield. Study on the fauna of predatory ladybugs associated with pomegranate orchards was conducted that were feeding on Aphis punicae in the Najafabad region (Isfahan province, Iran). Twelve species of 8 genera were collected Sampled specimens were identified according to their morphological, male and female genitalia characters using identification keys. The identified species were as follow: Adalia bipunctata (Linnaeus, 1758), Coccinella septempunctata Linnaeus, 1758, Coccinella undecimpunctata Linnaeus, 1758, Exochomus undulates Weise, 1878, Hippodamia variegate (Goeze, 1777), Hippodamia tredecimpunctata (Linnaeus, 1758), Oenopia conglobata (Linnaeus, 1758), Oenopia oncina (Olivier, 1808), Propylea quatuordecimpuctata (Linnaeus, 1758), Psyllobora vigintiduopunctata (Linnaeus, 1758), Scymnus syriacus (Marseul, 1868), Scymnus mongolicus (Weise, 1890).

Changes in numbers of adult Coccinellids on nettles infested with Microlophium evansi (Theo.) and on three experimental bean plots infested with Aphis fabae Scop. are described for the spring and summer of 1952 at Rothamsted. Of the three common species, Adalia bipunctata (L.), Coccinella septempunctata L. and Propylea quatuordecimpunctata (L.), the first was always the most abundant.The overwintered Coccinellids produced two broods: one on nettles in the spring and one on beans in early summer.On bean plots, changes in numbers of the adult insects occurred in three phases: (1) overwintered ladybirds, dispersing from nettles and other places, accumulated on the beans in the early stages of the infestations by Aphis fabae; (2) ladybirds, which had developed from eggs laid by the overwintered insects on nettles, emigrated from nettles and accumulated on the beans when A. fabae populations were at their height; (3) ladybirds, developed from eggs laid on the beans also by the overwintered insects, reached the adult stage when the bean aphid infestations had finished. The rise and fall of the A. fabae populations are discussed.One of the bean plots had always a high population of Coceinellids, which was attributed to its situation between two of the nettle sites. The other two bean plots were remote from nettles and one was sheltered by trees and buildings; their coccinellid populations were much lower.
