The incidence and duration of pupal diapause in Heliothis armiger in southeast Queensland were studied in 1976. 1977 and 1978. Larvae pupating before March formed non‐diapause pupae. A small proportion of those pupating in March formed diapause pupae, and the proportion increased until after late‐April when 62.5–100%) (mean 82%) entered diapause. Adult emergence from diapause pupae occurred from August to December with definite peaks in mid‐September to mid‐October and mid‐November to mid‐December
