Symptoms of damage:

• Young caterpillars cause small yellow mines on leaves
• Scrapping of epidermal leaf tissues producing typical whitish patches on leaves
• Full-grown larvae bite holes in the leaves and feeds on curd

Identification of pest:

• Egg: Minute yellow coloured eggs laid singly or in groups on the upper surface of leaves
• Larva: Pale yellowish green caterpillar

Management:

• Remove and destroy all debris and stubbles after harvest of crop
• Grow mustard as trap crop at 2:1 ratio (cabbage: mustard) to attract DBM for oviposition at least 10 days ahead of   planting of main crop
• Spray mustard crop with dichlorvos 76 WSC 0.076% to avoid dispersal of the larvae
• Pheromone traps @12/ha
• Crop rotation with cucurbits, beans, peas, tomato and melon
• Larval parasitoid: Diadegma semiclausm @1,00000/ha (Hills–below 25–27ºC) Cotesia plutellae (plains) at 20000/ha release from 20 days after planting
• Bacillus thuringiensis var kurstaki 2g/lit
• Neem seed kernel extract 5%
• Cartap hydrochloride 0.5% at 10,20 and 30 DAS (nursery) and primordial stage
