Abstract

In order to reduce the increasing use of chemical insecticides against cucumber (Cucumis sativus) pests (Bactrocera cucurbitae and B. dorsalis), a study based on crop combination was conducted to reduce the damage caused by these pests. From September to November 2001, four crop combination, the main one the cucumber’s crop and cucumber in monoculture (Control) have been conducted in Dabou. The cucumber culture was associated with the cultures of Mentha spicata, Mentha piperita, Manioh esculenta, and Zea mays. The cucumber in monoculture served as a control. The effectiveness of the crop combinations was evaluated by counting the number of fruits infested on a sample of thirty fruits piched every week during the entire fruiting period and then estimating the rates of infestation and reduction of fruit infestation for each parcel of cucumber in combination of culture. Cucumber cultivation in association with maize (Zea mays) crop recorded the lowest infestation rate (11.66 ± 1.27%) and the highest rate of fruit infestation reduction (78.30 ± 2.05%). This crop combination could then be recommended as part of the fight against fruit flies.
