Do Cutworms Eat Tomato Plants?

Tomatoes are a staple in many home gardens, and their popularity can be attributed to their versatility in the kitchen and their ease of maintenance. However, many tomato cultivators can attest to the frustration of losing plants to pests. One of the most common pests that affects tomato plants is the cutworm. In this article, we'll examine the behavior of cutworms and answer the question: do cutworms eat tomato plants?

What are Cutworms?

Cutworms are the larvae of several species of moths in the Noctuidae family. They are so named because of their tendency to "cut" the stems of young plants, causing the plants to die. Cutworms are typically gray or brown in color and are about an inch long when fully grown. They are most active at night and can be difficult to spot during the day.

Behavior of Cutworms

There are several different species of cutworms that attack tomato plants, and they all have slightly different behaviors. However, most cutworms prefer to feed on the stems of young plants. They will wrap themselves around the stem and use their strong jaws to cut through the plant's tissue. The plant will often fall over as a result of the damage, and it will eventually die. Cutworms will also feed on leaves, fruits, and other parts of the tomato plant if they are desperate for food.

Identifying Cutworm Damage

Cutworm damage can be difficult to identify because it often occurs at the base of the plant or underground. However, if you notice that your tomato plant has suddenly "fallen over" or if the stem looks like it has been "cut," it's a good indication that cutworms are present. In severe cases, you may also notice that the leaves of the plant have been partially or completely eaten.

Preventing Cutworm Infestations

Preventing cutworm infestations is key to protecting your tomato plants. There are several steps you can take to reduce the likelihood of a cutworm infestation:

Practice crop rotation. Cutworms thrive in soil that has been used to grow the same crops year after year. By rotating your crops, you can reduce the number of cutworms in the soil.

Set up barriers. Cutworms are not excellent climbers, so you can place a collar around each plant to prevent the worms from reaching the stem.

Encourage natural predators. Birds, beneficial insects, and even some species of nematodes will feed on cutworms. By attracting these predators to your garden, you can reduce the cutworm population naturally.

Apply insecticides. If all else fails, you can apply an insecticide that is labeled for use on cutworms. Be sure to follow the label instructions carefully.

Conclusion

In conclusion, cutworms are a common pest that can significantly damage tomato plants. They prefer to feed on the stems of young plants but will also eat leaves and fruits if necessary. To prevent cutworm infestations, gardeners can practice crop rotation, set up barriers, encourage natural predators, and apply insecticides if necessary. With these strategies, you can enjoy a bountiful harvest of healthy, ripe tomatoes.
