[Sexual dimorphism of guava weevil Conotrachelus psidii Marshall (Coleoptera: Curculionidae)].

We investigate structural and behavioral differences between male and female adults of guava weevil, Conotrachelus psidii Marshall, 1922 to help in sex determination. Weevils collected from a commercial guava orchard were individually caged and maintained under laboratory conditions. Every day ten individuals were grouped and their behavior was observed.
