Aphid parasitoids (Hymenoptera: Braconidae: Aphidiinae) on citrus: Seasonal abundance, association with the species of host plant, and sampling indices
Phytoparasitica 30 (4), 365-377
Abstract: Samples were collected from southern Greece during 1996–2000 in order to investigate the presence of parasitoids on Aphis gossypii Glover infesting several citrus species. The species of aphidiines found to have a significantly different preference for A. gossypii were Aphidius colemani Viereck, Aphidius matricariae Haliday, Diaeretiella rapae (M'Intosh), Ephedrus persicae Froggat, Lysiphlebus testaceipes (Cresson), Binodoxys acalephae (Marshall) and Binodoxys angelicae (Haliday). In another sampling experiment, the relative abundance of aphidiine parasitoids on aphids infesting orange and tangerine trees was studied in southern Greece (Nea Kios) in 1996 and 1997. A. gossypii constituted the largest part of the aphid population and was the only species parasitized. B. angelicae and A. colemani were the most abundant parasitoid species. The parasitization rate differed among the parasitoid species. B. angelicae had the highest colonization rate in centrally located and large host (A. gossypii) groups, whereas A. colemani was found in more isolated and relatively small host groups. The percentage of parasitism by B. angelicae was high mainly in large host groups, when B. angelicae was the only parasitoid present. However, in cases of coexistence of B. angelicae with A. colemani with hyperparasitoids, in the same sampling unit, the percentage of parasitism was relatively low.
