Comparison of Single and Repeated Bacillus thuringiensis (Bt) Applications in Controlling Multi-stage Outbreaks of Pteroma pendula (Lepidoptera: Psychidae) in Perak

Infestations of bagworm, Pteroma pendula (Lepidoptera: Psychidae), have severely affected local oil palm smallholders in Perak, Malaysia. Therefore, this study set out to assess the effect of single and multiple applications of Bacillus thuringiensis MPOB Bt1 (Bt), used as a bioinsecticide for controlling multi-stage P. pendula infestations at three severely infested (>100 larvae per frond) […]
