Red Palm Weevil (RPW), Rhynchophorus ferrugineus, is a serious pest of palm trees.
Eco-enzyme has been introduced as a solution to manage the RPW infestation. It was
prepared by using banana peel and are believes to be useful for weevil management
due to its anti-microbial properties. In this study, the presence of phenolic and
flavonoid compound of eco-enzyme banana peels was investigated if it could be
positively associated with anticellulase and antifeedant activity against RPW. The
cellulase activity of RPW was determined by using carboxylmethyl cellulose as
substrate. It showed that eco-enzyme banana peel can inhibit cellulase activity of
RPW. Antifeedant activity of eco-enzyme banana peel was tested against adults of
RPW by using the method of flour disc bioassay. The result showed that RPW has fed
on flour disc treated with eco-enzyme banana peel. In conclusion, banana peel ecoenzyme
has a potential to be used for RPW management.
