Aganaspis daci

Aganaspis daci (Weld)

(Also known as Trybliographa daci Weld)

Systematic position: Insecta, Holometabola, Hymenoptera, Apocrita, Chalcidoidea, Figitidae.

Geographical distribution: Of South-Asian origin, this species had been introduced into many regions for fruit fly control.

Morphology: The body of the adult is black with yellow legs, about 3.5 mm in length.

Life history: Aganaspis daci is an egg-pupal endoparasitoid of fruit flies. Its calculated threshold of development is around 9-11°C, and approximately 450 day degrees are required to complete a generation. Adults live for 2-3 weeks and lay ca 40 eggs/female at the optimal temperature range (23–25°C). At higher temperatures (above 30°C) they cannot complete their life cycle.

Economic importance: Aganaspis daci is a major controlling factor of Ceratitis capitata, at times killing >60% of the pests. In Israel it is an important enemy of C. capitata, and abroad it is a major parasitoid of Bactrocera zonata (the preferred host) and other fruit flies, like the Caribbean fruit fly, Anastrepha suspensa (Loew).
