Efficiency of degree-day of temperature on the activity of Bemisia tabaci (Genn.) was worked out, in the present study, over two tomato growing seasons (Nili plantations of 1996 and 1997). Results of this study infer that the degree-day model and the population of B.tabaci (Germ.) adults are highly correlated, and therefore, the degree-day model index (Heat units) could be taken as an indication on B.tabaci (Genn.) abundance on the tomato fields. The simple regression value (b) indicate that for every 0.5-0.6°C increasing in the degree-days, on an average, there is a 1% infestation in the population density of Etabaci adults and so on. Such results are very important for managing this pest.
