Urophorus humeralis

Urophorus humeralis, known generally as the pineapple beetle or yellow-shouldered souring beetle, is a species of sap-feeding beetle in the family Nitidulidae. It is found in Africa, North America, Oceania, Southern Asia, Europe, and temperate Asia. The species is known to be a vector of Ceratocystis paradoxa in sugarcane in Hawaii, and the beetles are attracted to diseased sugarcane more than healthy sugarcane, with Ceratocystis paradoxa being more nutritious to U. humeralis larvae.
