Abundance and visitation rate of apis pollinators on flowers of some multipurpose tree species grown in Muzaffarpur, Bihar, India

We investigated abundance and visitation rate of four honey bee (Apis) species on flowers of Litchi chinensis, Mangifera indica, Phyllanthus emblica and Psidium guajava, commonly grown in Muzaffarpur district (Bihar state, India). This observation revealed that the maximum flowers were visited during morning hours than those of the afternoon and evening hours. The temperature and humidity are likely to be the important factors which affect the abundance and visitation rate of honey bees. The present study can serve as a ready reference for researchers and beekeepers, especially in management of honey bee colonies and in understanding their foraging behaviour.
