THE BIOLOGY OF THE EUROPEAN CHERRY FRUIT FLY [RHAGOLETIS CERASI L. (DIPTERA: TEPHRITIDAE)]

A. Ozdem, N. Kilincer
The biology of the European cherry fruit fly [Rhagoletis cerasi L. (Diptera: Tephritidae)] was investigated in this study. The experiments were carried out in Cankiri-Eldivan, Ankara and Ayas in 2000. The first adult emergence dates varied between 12 and 15 May and 6 weeks after the first adult emergence reached peak flight. The adult flight duration was 81 to 86 days. The largest numbers of adults were caught with traps on the southern part of the tree canopy, which was followed by east, west and north traps, successively. The rate of infected fruits was about twice as high on upper vs. lower branches. All females trapped one week after the first adult was sighted had mature eggs. Females laid their eggs mostly on yellow, yellowish green and pink-yellow fruit; there were no eggs on mature or green fruit. The duration from egg to larvae was about 9 to 10 days. The larval development period ranged from 29 to 33 days. Even though one larva generally was observed per fruit, two or three larvae per fruit were observed with high population densities of cherry fruit flies. The first R. cerasi pupa was found between 18 to 21 June. In Central Anatolia, the pupal period lasted for nearly 11 months.
