blue orchard bee |
Osmia lignaria |
X-ray of Osmia lignaria cocoons taken in March. The white area of the abdomen is stored fat, which is depleted in these bees. This group of bees had low survival, probably due to being stored indoors over the winter and going into cold storage too late in the season.
Cocoon length 12-14mm. |

Ichneumonid wasp |
Campoletis sonorensis |
The adult wasp is black, slender and about 1/4- inch long but is rarely recognized in the field. The female lays an egg beneath the skin of a small budworm. The egg hatches and larva develops inside the budworm. When development is complete, the parasitic larvae emerges and pupates outside attached to a tobacco leaf. The silken cocoon is white, oblong, and about 1/4 inch long and is frequently attached to the skin of the host budworm. This parasite may kill 70% to 80% of the budworms in a field. |

Braconid wasp |
Cotesia congregata |
The braconid wasp is 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. |

Cotesia congregata |
This important parasitic wasp is a major factor in limiting hornworm numbers and damage, particularly late in the season. The tiny black wasp lays eggs in hornworms. Parasitized hornworms may be recognized by their shortened stubby horns. When these worms are broken open, the tiny, white parasitic larvae can be seen. When they complete their development, the parasites spin white, egg-shaped cocoons on the hornworm’s back. Parasitized hornworms damage tobacco much less and usually remain on the plant for a shorter time than normal hornworms. |
