This study was conducted to evaluate these variations in Varamin area during 2005-6. For this purpose, infested leaves of tomato, cucumber, egg plant and cotton collected from fields. Pupal cases mounted in microscopic slides. Then their main external morphological characters identified with taxonomical keys. Result showed that it has four host-correlated morphological variations. Description of these variation and their relationships are discussed in this study.
