Abstract

Twenty two insect species were recorded. Pests represented 89.29% while predators represented 7.5%. Spodoptera littoralis (Boisd.) constituted 53.34% of the total cath. Results showed an insignificant negative correlation occurred between monthly catch of both Paederus alfierii (Koch.) and both of Spodoptera littoralis (Boisd.) and S.exigua (Hb.) caught by a light trap during 8 months of investigation. The partial regression values of maximum and minimum temperature and relative humidity on populations of P.alfierii, S.littoralis and S.exigua were signifi­cant. Also, it was noticed that irrigation increase the catch.
