Diversity of fruit flies (Diptera: Tephritidae) of economic importance and their host plants in the sudano sahelian plateau of the Adamawa region (Cameroon)

Abstract

Fruit flies larvae parasitized ripe fruits and accelerate their rotting process causing nutritional and economic losses in Sudano sahelian plateau. The first step to implement a control strategy for these pests is the screening of the fruit flies occurring. The present study aims to identify fly species of economic importance in high Guinean-Savanna (Adamawa-Cameroon) and their host plants. Sampling of fruits were made on markets during 12 months. Four fruit fly species were collected: Bactrocera dorsalis (Hendel), Ceratitis fasciventris (Bezzi), C. cosyra (Walker), Dacus punctatifrons (Karsch). B. dorsalis was the most present and abundant species with 405 flies collected during the year. Infested fruits belong to six species: Psidium guajava (Myrtaceae), Mangifera indica (Anacardiaceae), Citrus reticulata (Rutaceae), Baillonella toxisperma (Sapotaceae), Citrullus vulgaris (Cucurbitaceae) and Annona senegalensis (Annonaceae). It’s in early rainy season, during the month of June that the most important fly species of economic importance were caught.
