Status of Procecidochares alani as a biocontrol agent for Ageratina riparia in Hawaii

Procecidochares alani, a stem-galling fly, was collected at 2000 foot elevation in Mexico in 1973 as a potential biocontrol of Ageratina riparia (the so-called "Hamakua pamakani"). It was released in Kona in 1974 at the 3400 foot elevation, and later at other locations on Hawaii's Big Island. By 1975, populations of the fly had built up, and--along with other biocontrol agents--had effectively decreased Ageratina riparia stands in many areas of Hawaii Island.
