Abstract: 
The number of adult B. tabaci on the 2 youngest leaves near the vegetation point fluctuated strongly on the cultivars of cassava included in the trials. No relation to the color of the petioles was observed. There was no consistent relationship between the number of vectors counted on the 3 local cassava cultivars as it varied with location and time of planting. The vector population decreased with the distance from the coast. When planting and sowing were carried out at the beginning of and during the rainy season, no extreme fluctuation of the vector population during the vegetation period occurred. The population increased in the dry season with subsequent watering. The decisive factor for the population fluctuation is the physiological age of the cassava plants and other nearby host plants of B. tabaci.
