Abstract

An experiment was carried out during 2007-08 at high altitude apple orchards in Uttarakhand to study the foraging behaviour of honeybees and syrphids during the bloom period of different apple cultivars in relation to prevailing weather conditions. Observations revealed a complete synchronization of blooming among different apple cultivars and their suitable pollinizers which ranged from 25 March to 17 April. Honeybee (Apis cerana indica Fabr.) was very efficient in foraging in terms of higher numbers of working bees visiting/m flowering branch/5 min. (12.22 and 14.32 in 2007 and 2008, respectively) during the peak foraging hours (8 AM-2 PM). Moreover, during morning (6-8 AM) and evening (2-5 PM) hours at very low temperature, A. cerana indica Fabr. showed a better foraging efficiency than A. mellifera L.
