Abstract

Most estimates of whitefly populations relate, according to the purpose of the survey, either to the adults or to the last two larval instars including the so-called “pupae”, these stages being easier to count than eggs or small larvae. Monitoring the adult population is done by visual counts or by catches with suction traps or yellow sticky traps. The latter are especially effective in detecting low density populations, but interpretation of the data has to take into account the activity pattern of the whitefly. Sampling of old larvae yields data on population density per leaf. The sampling design has to be adapted to the specific distribution of these stages which results from the biology of the pest. Possible ways to reduce the counting effort are discussed.
