ConRol Agent on Chromolaeno odorata m West Java Supervised by .SOEKISMAN
TJI@OSEMITO and KASNO.
The study is aimed at knowing the diwiibution area of Ceciddares comcm in West
JawSSamples w
e carried out h m ruSber plantaiions, abandoned field, forest and pasme. The
study wras done by visiting the area, but samples record the persent of h o t s of Chromolaena
odorafo,shoots w i t h gall number of eggs of Cecidochmes comero, number of flowver and s i ~ e
positions. The GPS data were maped, and analysii data Chromdoeno odoruio used to count shoot,
flowers, zAl and eo& Cecidochmes connexa for testing in Weeds Laboratory Biotrop, and done
regesior, analysis for knowing effect to Chromdaencr odorafatip and flower.
As weed biolwgml control agent io West Java, C e c i h c h e s connexa had established
almost in all study sites namely Parun-vjank Haurbenres, Panpdaran, Ciaren, Cikupa and
Cimulang but not Lemah Neun Deut, Cianjur, Paoglejar, dan Cikumpay. Its distribution areas the
