(2) cut off the leaves and kill the larvae when the young larvae are damaged by clusters. (3) spraying 20% dimethrin suspension 20% chlorpromazine 3 suspension or spraying Bt emulsion cyanobacteria in the whole larval stage. (4) when necessary, spray insecticides such as fenitrothion in the larval stage.
