Morphometric Analysis of Giant Honeybee, Apis Ddorsata Worker Bees of Different Areas of Mysore District, Karnataka, India
Journal Title: IOSR Journal of Pharmacy and Biological Sciences (IOSR-JPBS) - Year 2016, Vol 11, Issue 6
Abstract
The morphological characters of A.dorsata worker bees were analyzed after collecting moribund worker bees from different areas in Mysore District that experiences climate of semi-malnad type in southern dry zone part of Karnataka. Around 32 morphological characters were measured with the help of computer aided microscope Axion Vision ref. 4.8 software. The thorax, abdomen and overall body length showed significant variation between the workers bees. However, head length didn’t show significant variation (F=1.058; P>0.05) between the worker bees which belong to different areas. Interestingly, the head breadth, tongue length, mandible and antenna length showed significant variation (F= 6.599; P>0.05) between the worker bees collected from different areas of Mysore District. Further, length of thorax, length & breadth of fore wing, hind wing and hamuli numbers also showed significant difference (F= 18.23; P>0.05) between A.dorsata worker bees except the thorax breadth. Furthermore, fore leg and mid leg length showed significant difference (F=5.849; P>0.05) between worker bees of different areas excepting the hind leg. Pearson’s correlation studies revealed that there is a considerable relationship existed between few morphological traits and the body length of A. dorsata worker bees collected from different areas of Mysore District. Thus, it can be concluded that morphometric variations perhaps discriminate intraspecific groups of honeybee colonies as different ecotypes. Although it is simple, computer program-assisted morphometric analysis of the wing and body parts might provide useful information for honeybee biodiversity studies.
