RUBIO G, JOSÉ DAVID  and  ACUNA Z, JOSÉ RICARDO. Morphology of the digestive tract and female reproductive system of Compsus sp. (Coleoptera: Curculionidae). Rev. Colomb. Entomol. [online]. 2007, vol.33, n.2, pp.183-187. ISSN 0120-0488.

A morphological examination was conducted on the digestive tract and the female reproductive system of the citrus weevil, Compsus sp. (Coleoptera: Curculionidae). The digestive tract of Compsus sp. showed a typical arrangement as described for other insects. Morphological differences, however, were found in the crop of the foregut, which exhibited several spine-like structures. At the midgut level, the anterior ventricle was divided into medium-size sacs and numerous gastric caecae projected into the posterior ventricle. The female reproductive system showed a structural arrangement common to individuals of the family Curculionidae.
