Colopterus truncatus
Colopterus truncatus is a sap-feeding beetle in the family Nitidulidae with a broad distribution across the Americas. It has been documented as a seed predator of Inga marginata in Brazil, representing the first record of this trophic interaction. Males produce a species-specific aggregation pheromone composed of polyene hydrocarbons that attracts both sexes, with field activity requiring synergism with fermenting substrates. The species has also been identified as a principal vector of oak wilt fungus in Minnesota, highlighting its significance in both agricultural and forest ecosystems.
