Economic injury level of oil palm bunch moth, Tirathaba mundella walker for pest management recommendations in oil palm production

Oil palm bunch moth, Tirathaba mundella Walker is a notorious bunch feeding pest typically among oil palm aged 3-7 years old planted on peat. In order to manage the pest, an economic injury level (EIL) for the pest needs to be determined which could assist in decision-making if a control tactic is j...
