Abstract

The study was carried out at agricultural land of Phaldi, near Duttapukur (North 24 parganas, West Bengal, India) during 2012-2013 to document the diurnal insect diversity, their activities, roles and abundance in mustard (Brassica juncea L.) flower. 24 insect species belonging to 14 families under six orders were found at the day time in mustard blooms among which four species (Apis dorsata, Apis cerena, Apis florea, Vespa sp.) are pollen and nectar collectors (Pollinators), 13 insects were only nectar collector and rest species were only visitors. Number of species of order Lepidoptera and Hymenoptera were high at day time. But the abundance of Hymenoptera was observed maximum followed by Coleoptera and Lepidoptera during this study. Peak activity of the insect visitors was mainly observed at the middle of the day  i.e.  from  12  noon to 2  P.M. Among  the  three  honey  bee  species  the  abundance  of  A. dorsata  was  maximum  (18%)  followed  by  A. cerena  (15%)  and  A. florea  (4%).  It  was  observed  that  the  different  weather  conditions  effect  the  abundance  of  honeybees.
