Abstract

This work is a contribution to the knowledgement of the biology of Pachymerus nucleorum Fabr., 1792 (Bruchidae-Coleoptera) in coconuts of Syagrus oleraceae Mart. (Palmae). Among 16 couples species confined in laboratory from March 1977 to March 1978, we observed that each female made a maximum of three posture and the medium posture with 21.18 eggs. The medium period of pre-oviposition is 13 days and incubation period of 15.56 days. The pest presents five estages: larvae, pre-pupa, pupa and the adult forms, which were obtained in laboratory from 6 to 7 months. Mortality index of 33.12% was observed among larvae, pre-pupa, pupa and adult species. Also were developed observation in the eggs characteristics about fecundity, fertility, longevity of male and female and about pest habits.
