Abstract
The whitefly Bemisia tabaci （Gennadius） is an important economic pest, being a vector of Tomato yellow leaf curl virus （TYLCV）. In this study, we evaluated the inhibitory effect of two insecticides on TYLCV transmission by whiteflies. Tomato plants pretreated with pyrifluquinazon or dinotefuran （0 and 7 days before inoculation） were significantly less infected with TYLCV than untreated plants, while plants pretreated 14 day before inoculation did not show any difference. In contrast, the survival rates of viruliferous whitefly on pretreated plants 0, 7, 14 days before inoculation were significantly lower than those on untreated plants. These results indicate that sprays of these insecticides at 7-day intervals were effective in inhibiting the incidence of TYLCV transmission by whiteflies.
