COMPARATIVE MORPHOMETRIC STUDIES ON THE INDIAN HONEYBEE OF THE NORTH-WEST HIMALAYAS. 1. TONGUE AND ANTENNA
V K MATTU AND L R VERMA
Morphometricstudies were made on samples of workers of the Indian honeybee (Apis cerana indica F.) collected from various localities in the Himachal and Kashmir regions of India. Significant differences with localit y were found of postmentrum, pedicel, flagellum and antenna in the Himachal region but only in the postmentum in Kashmir. Values for the above morphological charaters were significantly higher for the mountainous(elevation > 1800m) than for the submountainous zone. In bees of Himachal, 5 characters-length of postmentum, scape, pedicel, flagellum and antenna - showed a low but statistically significant positive correlation with alititude, whereas in Kashmir only the total antennal length was correlated with altitude. Both length of flagellum and overall antennal length were significantly greater in Kashmiri bees. Tongue length did not differ significantly between the 2 regions; it is suggested that this character may be more closely related to floral morphology than to altitude.
