, : Abundance and population density of three Lepidopterous insects in Upper-Egypt (Lepidoptera: Noctuidae). Bulletin de la Societe Entomologique d' Egypte 1972; 55: 79-83

When light-traps were operated from April to November near Assiut in Egypt, peak numbers of Agrotis ipsilon (Hfn.) were taken in late April and in late September, peak numbers of Spodoptera exigua (Hb.) between late April and early May and between late September and early October, and peak numbers of S. littoralis (Boisd.) between late August and early October.o.
