| Abstract: | Effects of drip and furrow irrigation and their application at three different levels, onBemisia tabaci populations, were studied during the 1999 and 2000 growing seasons in Aydın, Turkey, with the objective of attaining water
rates of 100% (full), 66% (2/3) and 33% (1/3) during irrigation periods. All plots were irrigated during four different phenological
periods,viz., blooming, boll setting, boll and 5–10% of boll open stage. The number of whitefly immatures was significantly greater in
furrow-irrigated than in drip-irrigated plots in both 1999 and 2000 and there were significant differences found in the effect
of the irrigation methods and their application levels as well. In all trials, the number of whitefly nymphs was the highest
in the 33% (1/3) water supply with both drip and furrow methods.
