Descriptor: Cocoon(s)
Description: The braconid wasp an important parasite of the tobacco hornworm. The larval stage is a small, white legless grub that develops inside the hornworm. Parasitized hornworms are easily recognized after the wasp larvae spin their white football- shaped cocoons. When the parasite becomes an adult, it leaves through an opening in the end of the cocoon and searches for other hornworms. By late summer 90% or more of the hornworm found on tobacco may be parasitized. Hornworms with cocoons may live for several days but do not feed. Insecticides should not be applied if parasitized hornworms are abundant in the field.
