This study was conducted in March 2020 included four seasons, spring, early summer, late summer and autumn respectively at the apiary of the agriculture office, Sulaymaniyah / Kurdistan Region-Iraq.

Sixteen colonies with the almost same densities (4-5 bee frames) were randomly divided in to four groups, comprising four feeding treatments (Sugar solution as control, Wady Nektapoll+Sugar solution, Varroa Nektapoll+Sugar solution and Candy Shahang + Sugar solution).

The result showed that the highest numbers of workers prefer fed on Varroa nektapol plus Sugar solution was (627.500) worker inside the hives and (350.000) worker outside the hives The highest percentage of protein content in the workers body was (164.187 %) which fed with Varroa nektapol + Sugar solution and the lowest was (39.5 %) fed with sugar solution .The highest average of body weights of 5th larvae stage fed on Wady nektapol + Sugar solution was (116.250) mg in late summer season but the lowest was (63.750) mg fed on Sugar solution in autumn season.

The highest body weight of 10-day old workers was (110.750) mg fed on Varroa nektapol in spring season and the lowest was (78.500) mg fed on Sugar solution in autumn season.
