Also known as: common prickly pear, prickly pear, common pest pear

Profile

Impact

Common pest pear is native to south eastern USA, east coast of Mexico, northern South America, Cuba, Bahamas and Bermuda.

Common pest pear spreads by seed or vegetatively by segments which root where they contact the ground. The plant invaded large areas of northern NSW and central Queensland in the early 1900s and was infesting some 25,000,000 hectares.

Control

During the 1920s and 1930s various biological control agents were released for its control. Now common pest pear is largely controlled by cactoblastis, Cactoblastis cactorum. In areas where cactoblastis cannot complete 2 generations per year, it can be controlled by the cochineal, Dactylopius opuntiae.
