This research was carried out to evaluate the use of insecticide Imidacloprido + beta-ciflutrina on the number of visits by Apis mellifera bees in the sunflower flowers. The study was conducted in the month of December 2008 at the Experimental Station of Copagril, municipality of Marechal Cândido Rondon, PR. Five plants were marked before the period of flowering of hybrids M734, Charrua, Helio 250 e Aguará, with four replications. Two observers were two minutes on each plant, counting the number of bees in two intervals of time (from 8:30 to 10:30 AM and from 3:30 to 5:00 PM). The counting took place before the application of insecticide and 12h after using the product. It was found that there was significant effect of insecticide on the visitation of bees considering the data of all hybrids, the hybrid of the M734 and Aguará. There was no effect of insecticide on the visit considering the data of the hybrid Charrua and Helio 250.
