Introduction

Tomatoes are a popular plant to grow in home gardens and for good reason. Fresh, ripe tomatoes are delicious and make a great addition to many dishes. However, one of the biggest challenges of growing tomatoes is keeping them healthy and free from pests. One of the most common problems that gardeners face is finding their tomato plants stripped of their leaves. In this article, we'll explore what eats the leaves off tomato plants and how to prevent it from happening.

The Culprits

There are several insects that commonly eat the leaves off tomato plants. The most common culprits are tomato hornworms, aphids, and flea beetles.

Tomato Hornworms

Tomato hornworms are large, green caterpillars that can grow up to 4 inches in length. They are often found on the underside of tomato leaves and can quickly strip a plant of its leaves. If you suspect tomato hornworms are the cause of the damage, look for large, green caterpillars with white stripes on their sides. You can also look for their dark green droppings on the leaves.

Aphids

Aphids are small, pear-shaped insects that can be found on the leaves and stems of tomato plants. They suck the sap from the leaves, causing them to wilt and turn yellow. Aphids are often found in colonies and can be identified by their small size and pear-shaped body. They are usually green, but can also be black, brown, or yellow.

Flea Beetles

Flea beetles are small, jumping insects that feed on the foliage of tomato plants. They can quickly chew small holes in the leaves, causing them to look like they've been riddled with bullet holes. Flea beetles are often identified by their small size and their ability to jump when disturbed.

Prevention

Preventing the leaves of tomato plants from being eaten is important for maintaining plant health and productivity. There are several steps that gardeners can take to protect their tomato plants.

Hand Picking

One of the most effective ways to remove tomato hornworms from a plant is to hand pick them off. This can be done using gloves or a small tool like tweezers. Be sure to dispose of the caterpillars in a place where they won't damage other plants.

Natural Predators

Encouraging natural predators like ladybugs and lacewings can also help control aphid populations. These insects feed on aphids, helping to keep their numbers in check.

Row Covers

Using row covers can be an effective way to prevent flea beetles from feeding on tomato plants. Row covers are made of a lightweight fabric that allows sunlight and water to pass through, but prevents insects from feeding on the plants.

Chemical Controls

If natural methods are not enough to control the pest population, some gardeners may choose to use chemical controls. However, it is important to use these products carefully and according to their label directions, as they can be harmful to beneficial insects and may leave residue on the fruit.

Conclusion

While it can be frustrating to find the leaves of tomato plants eaten by pests, there are several steps that gardeners can take to prevent it from happening. By identifying the pests causing the damage and taking preventative measures, tomato plants can thrive and produce a bountiful harvest.
