The banana pseudostem weevil (BPW), Odioporus longicollis (Olivier) affects and cause decline of banana production particularly in small banana farms in Region 11 [Davao Region, Philippines]. The naturally occurring entomopathogenic fungus, Metarhizium anisopliae) Metch.) Sorok. is a potential biocontrol agent against many pests including banana weevils. The study aimed to asses the efficacy of three isolates of Metarhizium from field-infected Rice black bug (RBB) Scotinophara sp., Coconut leaf beetle Brontispa longissima Gestro, and BPW against BPW. Under laboratory conditions, the three isolates caused infection and death of BPW at varying spore concentrations. M. anisopliae isolated from RBB exhibited the highest mortality rate on BPW with 35.71, 50.00, and 64.29% at 1x10 sup 7, 1x10 sup 8, and 1x10 sup 9 spores/ml significantly reduced BPW population and caused 65.86% infection on trapped weevils.
