Resumen

Camu camu weevil Conotrachelus dubiae O'Brien, 1995 is a one of the main pests of camu camu (Myrciaria dubia H.B.K. Mc Vaugh) in Peruvian Amazonia. The aim of this study was to determine the biological cycle of this insect under laboratory conditions, to describe its behavior and population numbers under field conditions in Pucallpa, Ucayali, Peru. The percentage of hatching was 87%; the egg incubation period was 5.5±0.9 (4 to 7) days; the length of the larval stage inside the fruit was 22.2±1.9 (20 to 25) days, and the length larval stage (pre-pupa) underground was 54.4±5.5 (46 to 67) days. The length of pupal period was 11.8±0.9 (9 to 13) days, and the longevity of adults was 51.8±18.9 (9 to 75) days. Adults feed on fruits of different diameters and state of ripeness. Weevils also feed on buds, fresh branches and flowers. Adults of C. dubiae were only found in the rhizome, not in dry fruits or on the stem base.. The highest feeding and reproductive activity of adults was between 18:30 to 22:00 h. Adults were observed during the whole year, with the highest frequency between January and March in low seasonally flooded soils and between October to December in upland unflooded soils, coinciding with flowering and fruiting plant phenology.
