Abstract

Brinjal fruit and shoot borer Leucinodes orbonalis Guenee is an insect pest that causes major economic losses to brinjal in Malaysia. Field experiment was conducted at the experimental research farm (2°59'10.46"N, 101°44'8.78"E), Agriculture Faculty, Universiti Putra Malaysia (UPM), Selangor, Malaysia. Treatment plots were assigned in a randomized complete block design (RCBD) with three replications. Six treatments were evaluated as follows: T1(chlorantraniliprole 8.77% W/W + thiamethoxam 17.54% W/W (0. 4mL/ ℓ)), T2 (neem oil @3mℓ/ ℓ), T3 (yellow sticky trap and hand-picking), T4 (chlorantraniliprole 8.77% W/W + thiamethoxam 17.54% W/W (0.4 mℓ/ ℓ) + yellow sticky trap + hand-picking), T5 (neem oil + yellow sticky trap and hand-picking) and T6 (control). Results found that the lowest shoot infestation (0.53± 0.13 %) lowest fruit infestation by number (8.15± 0.75 %) and weight (5.88± 0.66%), maximum fruit yield (26.93± 0.10 t/ha) recorded in T4 (chlorantraniliprole 8.77% W/W + thiamethoxam 17.54% W/W + yellow sticky trap + hand-picking) treated plot.
