Description of a new species of Neralsia Cameron with a wide distribution in the American continent: N. incompleta n. sp. (Hymenoptera: Figitidae: Figitinae)

In this study a new species of Neralsia is described, N. incompleta n. sp. The radial cell shape allows to distinguish it clearly from the rest of species of the genus. The distribution of Neralsia incompleta n. sp. is probably the entire American continent, having been collected from Canada to Paraguay. In spite of its abundance, the associated biology is unknown, although it should be related with parasitism of Diptera Cyclorrhapha.     

Field parasitism of Ceratitis capitata larvae by Aganaspis daci in Chios, Greece

High parasitism rates were recorded in the Mediterranean fruit fly, Ceratitis capitata (Wiedemann) (Diptera: Tephritidae) in pupae derived from field infested figs, on the Greek island of Chios in 1999 and 2000. Adult parasitoids were identified as Aganaspis daci (Weld) (Hymenoptera:Eucoilidae), previously known as Trybliographa daci (Weld). Approximately 45%of C. capitata pupae yielded adultparasitoid in both years and the totalmortality of pupae due to the parasitoid was62–65%. Development of male A. daci at25°C, reared on 3rd instar larvaeof C. capitata, was shorter than that of the female (34 and 37 days respectively). Average adultmale longevity was 4–5 days longer than female(16–17 to 11–12 days, respectively) and almostidentical in wild and F₁ parasitoids ofboth sexes. We suggest that A. daci maybe an efficient form of biological control ofC. capitata in the Mediterranean regionand probably in other areas.
