A long‐term exposition of Spodoptera exigua (Hübner) larvae to fenitrothion caused abnormalities in egg structure. When examined under a scanning electron microscope, the eggs revealed diminutions and cracks around the micropylar and aeropylar region. The damage was proportional to the concentration of the insecticide. The observed changes may be one of the reasons for the decreased survival of populations exposed to fenitrothion.
