Aphids are small pear-shaped insects that can be yellow, pink, green, or black in color. They form colonies on the stems and leaves of tomato plants, sucking the sap and weakening the plant.
Red spider mites feed on the sap of tomato plants, causing the leaves to become yellow and mottled. They thrive in hot, dry conditions and can reproduce quickly – once a spider mite infestation is spotted, it may be too late to save your plant.
Cutworms are small green-grey caterpillars that eat through the stems of young tomato plants. They only feed at night, so it can be difficult to spot until the damage has been done, by which time it may be too late to save your carefully nurtured tomato plants.
Hornworms are large green caterpillars that feast on the foliage of tomato plants. They can be identified by the prominent ‘horn’ at the rear end of the body.
Colorado beetle also eats tomatoes, eggplant, and peppers. Both adult Colorado potato beetles and their larvae feed on the leaves of tomato plants, weakening the plant and causing low yields.
Flea beetles are small, shiny beetles that can leap into the air like fleas. They feed on tender young leaves, creating holes and ragged edges that can weaken the plant.
