Molecular identification of three aphid parasitoids, Aphidius areolatus, A. absinthii, and A. uzbekistanicus (Hymenoptera: Braconidae) from Ulleungdo and Dokdo Islands in Korea

A phylogeny of aphid parasitoids (Hymenoptera: Braconidae: Aphidiinae) inferred from mitochondrial NADH 1 dehydrogenase gene sequence.

Wasps of the braconid subfamily Aphidiinae are solitary endoparasitoids of aphids. Several aspects of their biology have been the focus of intuitive evolutionary hypotheses which could be tested with a robust phylogeny. Phylogenetic hypotheses have been proposed previously for aphidiines based on morphology, embryology, and DNA sequences. However, many of them are based on a limited number of c...

Potential Host Range of the Newly Introduced Aphid Parasitoid Aphidius transcaspicus (Hymenoptera: Braconidae) in Hawaii

Aphidius transcaspicus Telenga, a mealy plum aphid (Hyalopterus pruni Geoffroy) parasitoid from the Mediterranean, was recently introduced into Hawaii for control of invasive aphids. Under laboratory conditions the parasitoid successfully attacked several important aphid pests in Hawaii, including the melon aphid Aphis gossypii Glover, the banana aphid Pentalonia nigronervosa (Coquerel), the gr...

Morphological variation of Aphidius ervi Haliday (Hymenoptera: Braconidae) associated with different aphid hosts

BACKGROUND Parasitoids are frequently used in biological control due to the fact that they are considered host specific and highly efficient at attacking their hosts. As they spend a significant part of their life cycle within their hosts, feeding habits and life history of their host can promote specialization via host-race formation (sequential radiation). The specialized host races from diff...
