General Impact Notes

Most successful biocontrol program in Micronesia to date. Chromolaena suppressed and no longer a concern on islands wherein Pareuchaetes pseudoinsulata and Cecidochares connexa have established. P. pseudoinsulata populations and impact high initially, but decreased and variable here and other islands subsequently.
