Helicoverpa armigera (Hübner), the cotton bollworm, is the serious and commonly known pest in agricultural areas in the world. In this study, H. armigera was reared at 23±2°C, 65% RH and 16:8 h L:D in the laboratory on leaves and flowers of Gladiolus grandiflorus. The eggs were laid singly on the upper side of the G. grandiflorus leaves. There were 5 larval stages based on molts and head capsule measurements. The development of larvae was completed in an average of 16.75 ± 4.13 days and the survival rate was 64.1%. In this study, developmental period of larval stages, adult fecundity and pupal sex differentiation were determined on the ornamental host of the pest.
