Tomato hornworm (Manduca quinquemaculata) is a tomato pest with a big appetite! If left unchecked, it can consume a single tomato plant in just a couple of days. Itâs regularly confused with the tobacco hornworm (Manduca sexta), which is strikingly similar. Both feed on members of the Solanaceae (nightshade family) such as tobacco, eggplant, peppers, potatoes â¦ and of course tomatoes.
Biology. Tobacco feeding hornworms include 2 species, the tobacco hornworm (Manduca sexta) and the tomato hornworm (Manduca quinquiemaculata). These species are biologically similar but easily distinguished from one another both as larvae and adults.ornworms progress through 5 to 6 larval instars, with the majority of feeding occurring at fifth or sixth instar. Voracious feeders, two hornworm larvae are capable of completely defoliating a tobacco plant, and moderate populations in a field can result in significant damage. Tomato hornworm moth.
