Tomato hornworms are exclusively known to eat solanaceous plants (i.e., plants belonging to the nightshade family), with tomato being the most common host plant, followed by eggplant, pepper, and potato as less common hosts. Tomato hornworms can also be found eating solanaceous weeds such as horsenettle, jimsonweed, and nightshade.

Animal and Insects

In general, all tomato hornworms are herbivores, and they consume a wide variety of plant species. Some species, on the other hand, prefer specific plants over others. Hornworms have the ability to change color depending on the food they consume. In this section, we’ll take a quick look at some of the most common items that hornworms consume. 

Plants and Fruits

However, while hornworm chow (the paste in the cup) provides them with a complete diet, you can supplement it with other foods. Tomato hornworms eat mulberry tree leaves, green tomatoes, broccoli, spinach, celery, collared greens, red bell peppers, banana peels, and dandelion leaves if you’re short on time or money. Tomato hornworms can also eat tomatoes, other plants, fruit, cucumber, potatoes, lettuce, basil, pepper, plants, green, beans, dill milkweed, and peppers. 

What they don’t eat?

Among pet reptiles and amphibians, Tomato hornworms are a popular food source for both insectivorous and omnivorous species. They are the larvae (caterpillars) of the genus Manduca, which includes hawk moths and sphinx moths, among other species. Manduca sexta, popularly known as the tobacco hornworm, is the species of hornworm most commonly employed as a feeder.

Conclusion

Natural enemies of Tomato hornworms include parasitic Braconid wasps, which are essential and quite abundant. In the bodies of the caterpillars, the wasps lay their eggs, which hatch after a few days. Once the wasp larvae have completed their eating inside the caterpillar body, they eat their way out through the skin and spin cocoons on the caterpillar’s surface.. It is later that adult wasps emerge from the cocoons and attack other Tomato hornworms that they have cut out circular lids for. The killing of Tomato hornworms with parasitic wasp cocoons on their backs should be avoided if the hornworms are picked by hand.
