ETUDE PRELIMINAIRE DE L’EFFICACITE DU CITRON VERT (CITRUS AURANTIFOLIA, RUTACEAE) DANS LA LUTTE CONTRE LA NUISANCE SIMULIDIENNE A PETIT-GARANGO ET ALLANGBA-KONANKRO, VILLAGES RIVERAINS DE LA MARAHOUÉ, DANS LA COMMUNE DE BOUAFLÉ, CÔTE D’IVOIRE

Abstract

Entomological, parasitological and anthropological studies (surveys CAP: “knowledge, Attitudes and practicesâ€) have been undertaken to assess blackflies nuisance and test the effectiveness of lemon (Citrus aurantifolia, Rutaceae) on the reduction of the nuisance caused by Blackflies. The anthropological investigation showed that: • Petit-Garango and Allangba-Konankro populations are heavily bitten by Blackflies and young people are most vulnerable to the disease; • Blackflies are abundant in rainy seasons; • agricultural activities are highly disturbed by the blackflies aggressiveness; • skin lesions are due to blackfly bites; • to protect against the nuisance activity, most of the people use appropriate clothing (pants and long-sleeved shirts), industrial or natural products. The work done by the use of lemon as natural repellent has shown that the fruit juice ensures 89.3% protection against blackfly bites. The results obtained with the lemon juice are encouraging. The final objective is to obtain 100% reduction. To reach this goal, we need to extract the active ingredient in lemon, make it into of ointment, and then test it.
