Abstract
Four to five-year-old oil palm in an estate near Bagan Datoh Perak were severely damaged by Rattus argentiventer with even unopened male and female inflorescences being totally destroyed resulting in severe crop loss. Lethal feeding period tests showed second generation anticoagulant baits like 0.005 flocoumafen 0.003 brodifacoum and 0.005 brornadiolone to be effective against the rats 86-100 mortality being achieved by one to twodays; feed. However field application of up to four baits per palm showed very poor acceptance demonstrating behavioural resistance of the rats. Efforts to increase acceptance of baits by incorporating 4-allylanisole were unsuccessful. In a trial that evaluated 11 bait formulations wax bound cereal based bait with crude palm oil and dried anchovy heads incorporated was seen to be attractive to the rats in the field. Commercial baits formulated to this specification were however unattractive. Baits formulated on the estate and immediately applied were highly attractive with 68-97 uptake resulting in 77-100 control of damage. Customisation of formulation and freshness of bait would seem to be important towards control of behaviourally resistant rats in oil palm.
