Qualitative and quantitative host plant data are provided for palm bruchids in a part of Amazonia from
where previously few or no data were available. The host range and geographical distribution of several
species are extended. The role of fruit structure on susceptibility to bruchid infestation and fruit maturity
on oviposition site selection is discussed. The importance of mesologic conditions, particularly in areas
subjected to flooding, on population dynamics of palm seed beetles is stressed. A specialist parasitoid of
Caryoborus serripes, which is a specific predator of Astrocaryum nuts, is recorded for the first time; a
trichogrammatid parasitic on the eggs of the same bruchid is also identified.
