The objective of this study was to determine the biological cycle and life table of Cycloneda sanguinea L. fed with the aphid Aphis aurantii Boyer de Fonscolombe under laboratory conditions. The biological material was collected in jackfruit (Artocarpus heterophyllus Lam.) orchards located in the municipalities of San Blas and Compostela, Nayarit, Mexico. The experiments were carried out in the Laboratory of Parasitology of the Autonomous University of Nayarit, at a temperature of 25 ± 2°C, 70 ± 10% RH and a photophase of 12 hours. The duration of the immature phase was 19.32 ± 4.97 days, 197 Rodríguez-Palomera et al. Aspectos biológicos y parámetros poblacionales de Cycloneda sanguinea sobre Aphis aurantii and the longevity of the adults was 58.37 ± 3.44 and 61.71 ± 4.96 days, for males and females, respectively. The females presented a pre-oviposition period of 3.9 ± 0.31 days, with a fecundity of 882.2 ± 52.28 eggs / female. The survival curve was type I, which indicated that mortality mostly occurred in old individuals. The fertility curve showed two maximum oviposition peaks on days 9 and 36 after the emergence of adults. The net reproductive rate was 705.76 female eggs/female, in a generational time of 23.39 days, and a finite rate of increase of 1.41 individuals per day.
