Ceratitis capitata: Effect of host fruit size on the number of eggs per clutch
1985
McDonald, P.T. | McInnis, D.O.
A laboratory strain of Ceratitis capitata (Wiedemann) was presented with grapes, plums, apples and peaches for oviposition. Fruit diameter was highly correlated with the number of eggs/oviposition. Clutch size was 3.9 ± 0.3 for grapes (20 mm) compared with 14.0 ± 0.7 for apples (70 mm). When Parafilm®-enveloped whole peeled fruits and smaller spheres of fruit flesh were offered, fruit size proved more important than fruit type in determining egg clutch sizes. Ovipositions that required the puncture of fruit skin gave larger clutches than ovipositions through Parafilm or into punctured fruit.
