Abstract

Searching for morphometric differences between sexes in immature forms, the development of genital plates in the exuviae of Triatoma pallidipennis check for this species in other resources Stål 1872 nymphs was studied. Differences were found in the form and size of the 9th genital urosternite, it is larger and wider in males as compared to females. This difference is reported in several South American Triatoma check for this species in other resources species. From our results it is possible to sex early stages from microscopic observation of genital plates in whole insects.
