Investigations on temporal distribution of Bemisia tabaci (Gennadius) was carried out on 14 weeks old cotton genotype, RAS299-1, during 1987-1988 at Raichur (Karnataka). Oviposition was restricted mainly on the leaves of the youngest branches. Highest egg load of 89.16 per sq cm was recorded on youngest leaf of terminal host branch. Nymphal and pupal population was more on the middle leaves than on extreme leaves and followed a normal curve in their distribution. Adults exhibited similar trend in distribution to that of the egg stage
