- Abstract
Insects can significantly affect the overall profitability of a mungbean crop, reducing both yield and seed quality. Accordingly, insect damage is one of the main reasons for downgrading Vigna crops. The investigated items presented in this paper are following: main insects helicoverpa (Helicoverpa punctigera), mirds (green mirid - Creontiades dilutus and brown mird - Creontiades pacificus), green vegetable bug (GVB) (Nezara viridula), redbanded shield bug (RBSB) (Piezodorus oceanicus), large brown bean bug (Riptortus serripes), small brown bean bug (Melanacanthus scutellaris), bean podborer (Maruca vitrata) (previously Maruca testulalis), thrips, silverleaf whitefly (SLW); monitoring of insect attack; risk period and damage; thresholds of attack; control of pathogens. For a proper management of insect attack, crops should be inspected regularly (weekly) from the vegetative stage through to budding, and twice weekly from the start of budding-flowering through to the completion of pod fill. Crops which are producing buds, but not flowers, may contain damaging levels of sucking insects, causing the buds to abort before the flowers open. Mungbeans can compensate for early damage by setting new buds and pods but this may result in uneven maturity. Excessive early damage can delay harvest.
