Feedings habits of Paratanus exitiosus (Beamer), vector of sugar beet yellow wilt virus, wasstudied. It was found that this insect feeds primarly on parenquimatic tissue and that its survival is clase related to feeding on phloem tissues. This feeding habit seems to be related to the low efficiency of this insect as a vector.
