Abstract

Field investigations were conducted by employing direct visual count method (VCM) and an all out search method (AOSM) to record the impact of man-made activities to A. dorsata colonies at south-western Karnataka during 2010 to 2012. Farmers, residents and common public were met personally at arid, semi-arid and malnad regions and collected the information about trimming of tree limbs, colony hunting, colonies burning, uprooting of A. dorsata hosted trees with the help of pretested questionnaire. Total 27 visits were made to record the prevalence of man-made activities on A. dorsata colonies during rainy, winter and summer seasons separately. The interference due to trimming of tree limbs was more (6.5) and other activities namely colony hunting, colonies burning, uprooting of A. dorsata nested trees at/in the garden or croplands and clearing of normal colonies have claimed A. dorsata colonies less than 4 at south-western Karnataka. Analysis of variance of the data demonstrated the significant variation (F=3.988; P<0.05) existed between different man-made activities and the Pearson�s correlation analysis indicated positive correlation between man-made activities and the abandonment of A. dorsata colonies at south-western Karnataka. A. dorsata nest big sized colonies, attracted the attention of man for its sweet, energy rich high-value organic material called honey, brood and pollen. And, also due to fear of en mass attack and venomous sting of A. dorsata, its population in the wild is under threat. Therefore, its conservation is need of the hour as it is one of the major pollinator, its conservation is essential to restore local biodiversity
