Abstract

In Israel, Baizongia pistaciae (Homoptera, Pemphigidae, Fordinae) forms large galls on Pistacia palaestina. Population sizes on individual trees at 3 localities vary considerably among years, but often show a regular pattern of high and low gall densities on alternate years. Two of 5 possible explanations for the observed pattern can be regarded as working hypotheses. -from Author
