Abstract: Information about Corecoris dentiventris Berg, is mostly restricted to adult morphology, host plants and injuries. The objective of the present investigation was to study some reproductive parameters of this species. The experiment was carried out in a tobacco culture (Virginia type, var. K 326), in the experimental area of the Departamento de Fitossanidade of the Universidade Federal do Rio Grande do Sul, in Porto Alegre, RS. The reproductive parameters were estimated from ten couples isolated in plants, protected by cages, and observed until their death. The following average values were found: eggs/female = 355.9; pre-oviposition period = 11.8 days; oviposition period = 48.61 days; adult longevity = 62.6 and 66.1 days, respectively, for males and females. The reproductive potencial was estimated as 2.0 X 10⁴ descendents per female in tobacco crop.
