Abstract:

Sugar content, trehalase activity and trehalose level in drone prepupae of Apis mellifera carnica parasitized with varroa

Journal of Apicultural Science. Volume 49, Issue 1, Pages 79-84, ISSN (Print) 1643-4439
A study performed on drone prepupae of honeybees Apis mellifera carnica naturally infested with Varroa destructor showed a significantly lower sugar content, 7.08 ą 2.34%, as compared to 11.98 ą 2.16% in non-infested larvae. The trehalose level in infested larvae was also significantly higher than in their non-infested counterparts - 1.74 ą 0.46 % and 2.23 ą 0.39 % (p < 0.05), respectively. The latter difference may be the result of trehalase activity that was observed to be increased by one-half in infested prepupae. The results suggest that, as a result of Varroa infestation, the rate of saccharide consumption in drone larvae undergoes acceleration.
