Field Identification
Cabbage White Butterflies are common pests of brassica crops. The adult butterflies have white wings with small black spots, and their eggs hatch into caterpillars that feed voraciously on leaves, causing extensive defoliation.
These butterflies are medium-sized with predominantly white wings accented by black markings. Their larvae, known as cabbage worms, are green and can cause significant damage by skeletonizing leaves.
How to Deal With It
Organic Control Methods
Monitor brassica crops for egg clusters and early larval stages, and maintain plant health with balanced watering and fertilization.
Encourage natural predators such as parasitic wasps, birds, and predatory insects that target cabbage worms.
Employ crop rotation, interplant with repellent species, and use reflective mulches to deter adult butterflies from ovipositing.
Use floating row covers to prevent egg-laying and hand-pick larvae from infested plants.
Apply insecticidal soap or neem oil during peak infestation periods to control larvae while protecting beneficial insects.
