Abstract
This study was conducted to demonstrate seasonal and daily activity of the
adults of Tropinofa sequafida Scop. (Coleoptera: Scarabaeidae) on orange trees. The
experiment was carried out at Horticulture farm of Agriculture Faculty. AI Azhar
University throughout two successive seasons (2002 and 2003}. Results showed that
the main activity period of T. squalida adults was in the period extended from the end
of February to mid of April. The peak of its population was recorded in the second half
of March. Adults of this species were found more abundant at noon than other times
of the day. Also. the effect of both temperature and relative hunidity on beetles
population was studied and statistically analysed.
