Effects of irradiation on Mediterranean fruit flies (Diptera: Tephritidae): emergence, survivorship, lure attraction, and mating competition.

Irradiation of puparia in Mediterranean fruit fly, Ceratitis capitata (Wiedemann), sterile insect release programs can negatively affect adult fly performance. Emergence, survivorship, lure attraction, and mating competition tests were performed on irradiated and unirradiated Mediterranean fruit flies in Hawaii. Unirradiated flies of the Vienna-7 (tsl) strain had higher emergence, flight ability, and survivorship compared with irradiated flies.
