Abstract:
Impact of weather parameters on the population of pollinators visited on niger flowers grown under different dates of sowing showed that the minimum temperature significantly influenced the population of Apis cerana indica and Apis mellifera in all most all the dates of sowing. Similarly evening relative humidity had significant impact on the population of Apis dorsata in 15^th July and 15^th August sown crop while in other dates of sowing non-significant impacts were observed. Sunshine hours had significant negative impact on the occurrence of Apis cerana indica under 5^th (25^th August) and 6^th (6^th September) dates sown crop while non-significant impacts were observed in other dates sown crop. The vapor pressure morning and evaporation had significant impact on the population of Apis mellifera under 5^th August, 25^th August and 5^th September sown crop however non-significant impacts were observed in other dates crop. Similarly vapor pressure evening had significant impact on the population buildup of Apis cerana indica in 15^th August, 25^th August and 5^th September sown crop while for others dates sown crop had non-significant impact on the population of Apis cerana indica.
