Abstract :

The present investigation on morphometric variations in Apis cerana and A. florea was conducted in the Department of Agricultural Entomology, Killikulam, TNAU during 2012-13. Reddish honey bees are said to possess resistance to diseases. We screened the Indian bees, Apis cerana and the little bees, Apis florea available on the campus for any morphological colour variation besides hamuli number on the hind wings. They were examined for the colour variation in abdominal tergites and sternites and the thoracic scutellum. The number of hamuli present on the hind wing were also examined. The results indicated no significant variation in colour and hamuli. All bee colonies sampled in the campus were yellowish in colour, except for the black scutellum in A. florea. The number of hamuli averaged 18.0 in A. cerana and 11.0 in A. florea.
