Urophorus humeralis
pineapple beetle, yellow-shouldered souring beetle
Urophorus humeralis is a sap-feeding beetle in the family Nitidulidae, commonly known as the pineapple beetle or yellow-shouldered souring beetle. The species has a remarkably broad distribution spanning Africa, North America, Oceania, Southern Asia, Europe, and temperate Asia. It is an agricultural pest with documented associations to multiple crop plants, including a first reported infestation of pear fruits in China. The species has been identified as a vector of the plant pathogen Ceratocystis paradoxa in sugarcane in Hawaii, with adults preferentially attracted to diseased over healthy plant material.
