Tomato worm, also known as the hornworm, is a pesky insect that feeds on tomato plants. These green caterpillars can quickly devour leaves and fruits, causing significant damage to the plant. Besides tomato worm or hornworm, these pests are also sometimes referred to as tobacco hornworm or manduca caterpillar. While the names may differ, the solutions to dealing with them are similar. Organic control methods include handpicking, using natural predators like wasps, or spraying with Bacillus thuringiensis, a naturally occurring bacteria that targets the caterpillars. Whatever the name, tomato worm or hornworm, it's essential to stay vigilant and take necessary measures to protect tomato plants from these destructive insects.
