Introduction

As the summer months approach, many gardeners are preparing to grow delicious tomatoes in their gardens. However, one major concern for tomato growers is the damage that caterpillars can cause to tomato plants. In this article, we will explore what caterpillars eat on tomato plants and provide tips on how to prevent caterpillar damage.

Caterpillars and Their Diet

Caterpillars are the larval stage of butterflies and moths, and they can cause significant damage to tomato plants during feeding. Some common caterpillars that feed on tomato plants include the tomato hornworm and the armyworm. These caterpillars feed on the leaves, stems, and fruit of tomato plants, often leaving behind large holes and extensive damage.

As for what caterpillars eat on tomato plants, the answer is quite simple – they eat everything. Caterpillars are not picky eaters and will consume any part of the tomato plant they can get their mandibles on.

Signs of Caterpillar Damage

It’s important to be able to recognize the signs of caterpillar damage early on to prevent extensive damage to your tomato plants. Here are a few signs to look out for:

Holes in leaves or fruit

Chewed or damaged stems

Fecal matter, called frass, on the plant or surrounding area

Presence of caterpillar larvae on the plant

Preventing Caterpillar Damage

The best way to prevent caterpillar damage is through proactive measures. Here are some tips on how to keep your tomato plants safe from caterpillar damage:

Hand-pick any caterpillars off the plant and dispose of them

Apply Bacillus thuringiensis (Bt), a bacterial spray that targets caterpillars, to tomato plants

Use row covers to physically prevent caterpillars from accessing your plants

Plant companion plants that deter caterpillars, such as marigolds or basil

Conclusion

Caterpillar damage can be a significant problem for tomato growers, but with the right knowledge, gardeners can take proactive measures to prevent damage. By understanding what caterpillars eat on tomato plants, recognizing signs of damage, and taking preventative measures, you can ensure a healthy and bountiful tomato harvest.
