The current study was conducted at Agriculture Research Institute Ratha Kulachi, Dera Ismail Khan, to study the population dynamics of insect pollinators on Black Cumin during 2014. A 100m2 plot was selected for research purpose. The Insects were observed twice a day i.e. from 9:30-10:30 am and 2:30-3:30 pm from the beginning of flowering stage up to the crop maturity i.e. 7 February to7 March. Nine species of pollinators belonging to class Insecta were recorded, in which four were Dipterous (Syrphid fly) that is Episyrphus balteatus De., Melanostoma orientale Wied.,Eupeodes bucculatus Rond. and Eristalis tenax L. Three belonging to order Hymenoptera (two were honey bees i.e. Apis dorsata Fabr. and Apis florea Fabra., while one was small carpenter bee i.e. Ceratina spp Latr.) and two belonging to order Lepidoptera i.e. Cabbage Butterfly (Pieris brassicae L.) and Monarch Butterfly (Danaus chrysippus L.). Apis florea was recorded very high with a percent value of 36.79% as compare to other species, followed by Pieris brassicae and Apis dorsata with values of 14.5% and 12.5% respectively, while Eristalis tenax and Danaus chrysippus were reported to have the lowest population of similar values of 3.53%. The population of Apis florea, Apis dorsata, Ceratina spp, Pieris brassicae and Melanostoma orientale were more with values of 57%, 54.7%, 60%, 51.30% and 52% respectively at 2:30-3:30 pm than morning. On the other hand the population of Danaus chrysippus was equal at both the time intervals during the research period.
