How to Manage Pests

Pests in Gardens and Landscapes

Natural enemies

Two parasites attack the larvae of the citrus cutworm and appear to be highly effective in reducing the next year's population. A parasitic wasp, Ophion sp., attacks almost mature larvae, which are still able to construct a pupal case; the parasite larva then consumes its host and pupates inside the protective earthen cell. The parasite pupa is light brown with a darker band around its midsection.

Another parasitic wasp, Banchus sp., also attacks cutworm larvae but is less frequently found.
