All four species of … Recent observations of papaya fields in India indicated that there has been a continued increase in the incidence of papaya leaf curl disease (as shown by symptoms), resulting in severe economic losses. However, holding the population of whiteflies in check can reduce the severity of the infection. The earliest symptoms are a yellow mottling of leaves and vein-clearing of leaves. Alternative hosts are tomato and tobacco plants. Dark green streaks may develop on leaf petioles and the main stem.
