Do Cicadas Harm Tomato Plants?

As the brood of cicadas emerges once again in some parts of the United States, gardeners are wondering if these insects pose a threat to their beloved tomato plants. Cicadas are known for their loud singing and swarming behavior, but what impact do they have on vegetable gardens, specifically tomatoes?

The Life Cycle of Cicadas

Cicadas have a unique life cycle compared to other insects. They spend most of their lives underground as nymphs feeding on the roots of trees and other plants. After 13 or 17 years (depending on the species), the nymphs emerge from the soil and mature into winged adults. The males then sing loudly to attract females in order to mate and lay eggs for the next generation.

What Do Cicadas Eat?

Adult cicadas don't eat much, if anything at all. Their sole purpose is to mate and lay eggs, and they typically die after a few weeks. However, nymph cicadas feed on plant roots for several years before emerging as adults. While they may cause some damage to young trees and shrubs, mature plants are generally not affected.

Do Cicadas Harm Tomato Plants?

Fortunately, tomato plants are not one of the preferred hosts for cicadas. While they may occasionally feed on tomato roots, it is unlikely to cause any significant harm to the plant. In fact, many gardeners have reported thriving tomatoes in areas where cicadas are abundant.

Preventative Measures

If you're still concerned about cicadas and your tomato plants, there are a few preventative measures you can take. One option is to cover your plants with a fine mesh netting to prevent cicadas from accessing the roots. Another option is to plant your tomatoes in containers above ground, away from the cicadas' reach. However, it's important to note that these measures may not be necessary or effective in most cases.

The Benefits of Cicadas

While cicadas may seem like a nuisance to some, they actually play an important role in the ecosystem. Their feeding on tree roots can actually help promote new growth and increase soil aeration. Additionally, their emergence from the soil serves as a food source for many animals, including birds, rodents, and even some humans who enjoy eating the insects (known as entomophagy).

In Conclusion

If you're worried about cicadas harming your tomato plants, rest assured that mature plants are unlikely to be significantly affected. Take simple preventative measures if necessary, but consider the benefits of these fascinating and unique insects in the ecosystem. As gardeners, learning to coexist with the natural world can only enhance our appreciation for the beauty and diversity it provides.
