A description is given of the development of Monistria discrepans (Walker) in the laboratory. The eggs undergo a diapause which is broken by incubation at low temperatures. Duration of nymphal development varies with temperature above 20°C and lasts 33.8 d for males and 47.7 d for females at 35°C. Survival is best (58%) at 25 and 30°C. The lifespan of females is more than 175 d at 27.5°C during which they produce an average of 1.71 egg pods with 31.8 eggs/pod. This slow rate of development and poor reproduction in the laboratory render the species unsuitable as a candidate for mass production.
