Abstract

FERREIRA, Sidney Alberto do Nascimento; GENTIL, Daniel Felipe de Oliveira  and  SILVA, Neliton Marques da. Damage of camu-camu (Myrciaria dubia) fruits by Conotrachelus dubiae (Coleoptera: curculionidae) in Central Amazonia. Rev. Bras. Frutic. [online]. 2003, vol.25, n.3, pp.544-545. ISSN 0100-2945.  http://dx.doi.org/10.1590/S0100-29452003000300047.

In Brazil, the occurrence of Conotrachelus dubiae O'Brien, 1995 (Coleoptera: Curculionidae) in camu-camu [Myrciaria dubia (H.B.K.) McVaugh, Myrtaceae] had only been verified in natural populations. This report describes its occurrence in an experimental cultivation, where damage of camu-camu fruits by C. dubiae at different ripening stages was evaluated between 1999 and 2003. The damage caused by the larva increased with the degree of ripening of the fruits, with greater damage of fruit pulp (30 to 90%) than to seeds (7%). The incidence of this insect may cause significant quantitative losses in the camu-camu production.

Keywords : camu-camu borer; Insecta; cultivation in amazonian floodplain.
