![]() ![]() The wasp larvae then emerge from the fourth or fifth instar hornworm and pupate in white cocoons on their backs. As the caterpillars mature, so do the wasp larvae. These wasps lay their eggs inside of first to third instar hornworm larvae. The most obvious hornworm parasitoids are Cotesia congregata. Many native biological control agents feed on hornworms in North Carolina, and these predators and parasites play an active role in reducing the damage hornworms cause. See the North Carolina Agricultural Chemicals Manual for registered materials and use recommendations. Since larvae with parasite cocoons eat much less, they should be counted as 1/5 of a caterpillar, meaning five worms with cocoons equal one healthy worm. Treatment is justified when one or more hornworms larger than 1 inch and without parasite cocoons ( Cotesia congregata) are found per 10 plants checked.
