Influence of pollen traps on some biological activities and bee venom quantity of honeybee colonies

Abstract

The relation between pollen trap types (Outside and inside pollen traps) and some biological activities including the weight of collected
bee venom was conducted during the experimental period. Results show that colonies with outside pollen traps recorded a higher value of sealed worker brood cells, bee honey, and bee bread than those with inside pollen traps. Significant differences were recorded between inside and outside pollen traps in the amount of stored bee bread on all dates. The mean weight of captured pollen gives significant values in colonies with inside pollen traps during the treatment period. A negative correlation was recorded between the amount of bee bread and pollen weight in colonies with outside pollen traps. A positive correlation was recorded between the sealed brood area and the amount of bee bread in colonies with inside pollen traps. The highest significant amounts of bee venom were collected in colonies without pollen traps. A remarkable decrease in bee venom and bee bread amounts was observed in colonies provided with pollen traps. Colonies with inside pollen traps showed a negative correlation coefficient between pollen weight and the amount of collected bee venom.
