Loopex® Biological Insecticide for Cabbage Looper Control

Baculovirus for Cabbage Looper Control

Loopex® is a baculovirus-based biological insecticide used to manage cabbage looper larvae in greenhouse and open field vegetable crops. It fits within IPM programs and is suitable for organic production.

It must be ingested by susceptible larvae to be effective. Upon ingestion, occlusion bodies dissolve in the larval midgut, releasing viral particles that infect and replicate in host tissues. Infected larvae stop feeding, become sluggish, and die within 4 to 9 days, with viral particles released into the environment contributing to further spread within the pest population.

For best results, apply at early larval stages before significant feeding begins. Monitoring moth activity and crop development supports accurate timing.

Target Pest Information

Cabbage Looper (Trichoplusia ni)

The cabbage looper is a common caterpillar pest of vegetable crops, particularly brassicas, and is easily identified by its looping movement. It affects crops such as cabbage, broccoli, cauliflower, kale, lettuce, spinach, celery, peas, potatoes, and tomatoes. Larvae cause significant feeding damage, creating large holes in leaves, contaminating produce, and reducing crop quality, while often hiding within dense foliage or heads, making infestations harder to detect. Eggs are laid on the underside of leaves and hatch within a few days, with multiple generations occurring each season. Monitoring should begin early using crop inspection and pheromone traps.
