Tobacco hornworms can be controlled in various ways and immediate management is recommended if this pest is detected in a garden or field setting.

This method of cultural control requires regular scouting of solanaceous plant species, looking for signs of feeding damage. The caterpillars themselves can be hard to see against the green foliage of the host plant, so careful monitoring of defoliation or the presence of frass ( Figure 11) may be better indications of caterpillar presence.

- The larval stages of Manduca sexta are voracious feeders. Larvae feed by consuming the leaves of solanaceous plants, often stripping entire leaves to the midrib, defoliating the plants (Figure 9). Though considered a common garden pest, tobacco hornworm can cause significant economic damage to tobacco crops and occasionally tomato and potato crops....
