The parasitoid wasp Trichogramma attacks M. quinquemaculata eggs. The larvae of the wasp develop in the egg, preventing the development of the caterpillar larvae. Trichogramma is a natural enemy of M. quinquemaculata and has also been used as a biological control agent by humans. [13] closely related tobacco hornworm parasitized by braconid wasp
Adult wasps lay their eggs in tobacco hornworm (Manduca sexta) and tomato hornworm (Manduca quinquemaculata) larvae in their 2nd or 3rd instar (each instar is a stage between moltings, i.e. the second instar is the life stage after the first molt and before the second molting) and at the same time injects symbiotic viruses into the hemocoel of the host along with some venom.
Many tomato-growers have seen the fruits of an elfin wasp, known as Cotesia congregata. Females inject eggs into the tobacco hornworm, a caterpillar noted for feasting on tomato plants.
Manduca sexta is a moth of the family Sphingidae present through much of the Americas.The species was first described by Carl Linnaeus in his 1763 Centuria Insectorum.. Commonly known as the Carolina sphinx moth and the tobacco hawk moth (as adults) and the tobacco hornworm and the Goliath worm (as larvae), it is closely related to and often confused with the very similar tomato hornworm ...
Tomato Hornworms. lauraag / Getty Images. As its name suggests, the tomato hornworm loves tomatoes. But they will eat other fruits and vegetables as well. These caterpillars are green with a ...
Wasps come in a variety of colors — from yellow and black to red and blue — and are split into two primary groups: social and solitary. Most wasps are solitary, non-stinging insects that do ...
Hornworm with parasitic wasp cocoons Some parasitoid wasps mark the host with chemical signals to show that an egg has been laid there. This may both deter rivals from ovipositing, and signal to itself that no further egg is needed in that host, effectively reducing the chances that offspring will have to compete for food and increasing the ...
Cotesia is a genus of braconid wasps first described by Peter Cameron in 1891. Some species parasitize caterpillars of species considered pests, and are used as biocontrol agents. Cotesia congregata parasitizes the tomato and the tobacco hornworms. C. glomerata and C. rubecula feed on the cabbage white and other white butterfly caterpillars.
