The results indicated that the population was at its peak from second week of January to last week of March (2nd to 13th MW) and third week of December to first week of March (50th to 9th MW). The first peak of 23.00 whitefly/plant occurred during 7th MW (12 to 18 February) in summer 2014 and during summer 2015, with the maximum population of 23.50 whitefly/plant being observed during 6 to 12 February.
