Known as the tobacco budworm (when it is on tobacco plants), this is one of three insect species that is called “bollworms” (when they are on cotton plants). As part of Integrated Pest Management (IPM), farmers can utilize the parasitic Euplectrus comstockki wasp to help control the tobacco budworm/cotton bollworm. When that wasp’s venom is injected into Heliothis larva, it stops the larva from molting (and thus maturing).
