In Lima, under laboratory conditions, the biological cycle of Nysius simulans was studied in 3 generations using three commercial varieties of quinoa as food diet. The duration of the total biological cycle was under environmental conditions 59.56 days (T ° = 27.1 ° C, HR = 81.8%) and under controlled conditions 58.54 days (T ° = 26.6 ° C, HR = 46.4%) the analysis of variance indicated that for the treatments evaluated (Blanca de Hualhuas, Pasankalla, Rosada de Huancayo) there were no significant differences. The period of incubation of eggs was under environmental conditions 7.91 days and under controlled conditions 6.98 days, the analysis of variance indicated that for the evaluated treatments there were significant differences. Five nymphal stages were recorded and the duration was under environmental conditions 22.33 days and under controlled conditions 22.40 days, the analysis of variance indicated that for the treatments evaluated (Blanca de Hualhuas, Pasankalla, Rosada de Huancayo) there were significant differences. Likewise, the number of postures (106.5 and 97.3 eggs, respectively) was determined under controlled and environmental conditions, the analysis of variance indicated that for the treatments evaluated there were significant differences where the Pasankalla treatment resulted in a greater number of postures. At average environmental conditions, the pre-oviposition period is 4.17 days, oviposition is 23.17 days, post-oviposition 1.97 days, the analysis of variance indicated that there were significant differences between treatments. At controlled conditions, the pre-oviposition period is 3.89 days, oviposition is 23.13 days, postoviposition 2.13 days, the analysis of variance indicated that there were no significant differences between treatments.The length of the labium was determined under environmental conditions at the level of nymph V there were only significant differences in generation 2 (G2) where the treatments Blanca de Hualhuas (1,175 mm) and Rosada de Huancayo (1,169 mm) were statistically superior to the Pasankalla treatment ( 1,111 mm), under controlled conditions at level of nymph V in the treatments evaluated there were no significant differences. The length of the eggs was also determined under environmental conditions, it was 0.915 mm and under controlled conditions it was 0.916 mm and there were no significant differences between the treatments. The length of the adults was also determined to environmental conditions, resulting 3.26 mm, under controlled conditions it was 3.20 mm and there were no significant differences between the treatments. Likewise, the number of copulas was determined at environmental conditions, resulting in 1.43 copulas / day with an average of 30.20 minutes / copulation, while at controlled conditions it was 1.30 copulas / day with an average of 30.82 minutes / copulation.
