More than 500 plants species are listed as host of whitefly which transmit at least 19 viral diseases. In Pakistan whitefly (Bemisia tabacci) is becoming increasingly important since the outbreak of cotton leaf curl virus in cotton crop. Based on virus transmission efficiency and biological characteristic of whitefly colonies reared at Plant virology Lab., NARC on cotton plants, it was suspected that perhaps more than one population of whitefly are present. This raised our interest in genetic variation existing among whitefly population. Above 30 random samples were taken from whitefly colony maintained on cotton. Genetic variation among these samples was observed using isozyme electrophoresis patterns of adult whiteflies. Differences in esterase banding patterns have been observed indicating that more than one populations exist.
