Abstract
Between 1984 and 1988, a survey of fruit-infesting ceratititl fruitflies was conducted in 11 agricultural districts in Kenya. Samples of up to 18 different fruit crops were examined for infestation. The four species of fruitfly found were Ceratitis capitata, C. rosa (Pterandrus rosa), C. nigra (Trirhithrum coffeae) and C. cosyra (Pardalaspis cosyra). The first three were sympatric infestants of coffee, while the latter was exclusively found in mangoes. In addition, C. rosa also infested loquat, guava and custard apple. C. capitata infested commercial orange cultivars. This species was predominant in the main arabica coffee growing areas in the central highlands. C. rosa and C. nigra were more widespread, occurring in high proportions in most parts of the country. Generally, the proportions of the three species per coffee sample, and the mean number of each species per kg of coffee, tended to vary considerably over time and space.
Résumé
Dans il régions agricoles au Kenya une prospection sur les mouches fruitiéres a été effectuée entre 1984 et 1988. Jusquà 18 espéces d’arbres fruitiérs ont été examinés pour infestation. Quatre espéces des mouches fruitiéres ont été déterminées. Ceratitis capitata, C. rosa (Pterandrus rosa) et C. nigra (Trirhithrum coffeae) infestant le caféier tandis que C. cosyra (Pardalaspis cosyra a été trouvé exclusivement sur la manguier. En plus, C. rosa infestait le bibacier, le goyave et l’Annona. C. capitata infestait les orangers. Cette espéce est prédominant dans les “Central Highlands” où on cultive le caféier arabica. Par contre, C. rosa et C. nigra étaient omniprésents. Une variation considérable a été observé dans l’espace et dans le temps, dans la distribution proportionelle des trois espéces sur les échantillons sur caféier.
