  abstract = {{A}frican cassava mosaic virus ({ACMV}), vectored by the whitefly, #{B}emisia tabaci$ ({G}ennadius), is considered the most damaging pathogen of any {A}frican crop. {I}nformation about vector movement is important for understanding the epidemiology of this disease and the experiments reported here were designed to examine #{B}. tabaci$ flight activity both in and around a cassava crop in relation to time of day, crop growth stage, wind direction and speed, and to the resulting pattern of infected plants within the field at harvest. {A}t wind speeds of < 1.4 m/s, adult #{B}. tabaci$ approached the yellow traps by flying upwind. {A}t greater wind speeds, significantly fewer #{B}. tabaci$ adults approached the traps from downwind, thus reversing the directionality of the catch. {W}hen the direction of the prevailing south-west wind reversed, so did the directionality of the catch. #{B}emisia tabaci$ adults were flight active throughout the day and the greatest percentage were caught above the canopy between 06.00-08.00 h, when wind speeds were lowest. {T}rap height and position significantly affected catch with the greatest numbers caught on the lowest traps. {M}ore than three times as many #{B}. tabaci$ adults were caught on traps situated downwind from the field compared to those upwind, suggesting that the field was acting as a source of whiteflies. {I}n both years, {A}frican cassava mosaic disease ({ACMD}) incidence was highest and lowest, respectively, on the edges and in the middle of the trials, with the highest incidence occurring on the edges facing the prevailing wind direction. {T}hese results are discussed in relation to the epidemiology of {ACMD} and to potential cultural control methods such as the use of {ACMD}-resistant guard rows to protect a mainly susceptible crop.
