Introduction

As the weather gets warmer, the sound of cicadas fills the air. While some may enjoy the chorus of these insects, others may wonder about the impact they have on plants and trees. In this article, we will explore the relationship between cicadas and vegetation.

The Life Cycle of Cicadas

Cicadas are best known for their characteristic buzzing sound, which is made by males to attract females. However, they also play an important role in the ecosystem. Cicadas spend most of their lives underground as nymphs, feeding on sap from plant roots. After 13 or 17 years (depending on the species), they emerge from the ground as adults, mate, and lay eggs on branches of trees and other vegetation.

Negative Impacts of Cicadas on Plants and Trees

While cicadas may not directly harm plants and trees during their nymph stage, they can cause damage as adults. Female cicadas use a sharp, pointed ovipositor to lay their eggs on the bark of branches. This can cause damage to the tree by creating a wound where diseases or pests can enter. In addition, cicadas can cause stress to trees by removing sap from branches and leaves, which can weaken the tree and make it more susceptible to disease.

Positive Impacts of Cicadas on Plants and Trees

Despite the negative impacts of cicadas on plants and trees, they also have positive effects. As nymphs, they help regulate the growth of plant roots by feeding on sap. The emergence of cicadas at the end of their life cycle can also benefit the ecosystem by feeding predators such as birds, squirrels, and other animals. In addition, the eggs laid by cicadas can provide a nutrient-rich food source for animals such as ants.

Management of Cicada Damage

If you are concerned about the damage caused by cicadas, there are several management strategies you can use. One approach is to protect small trees and shrubs by covering them with nets or cloth. This can prevent cicadas from laying their eggs on the branches. In addition, you can prune any damaged branches to remove the affected areas and prevent the spread of disease. Finally, maintaining proper care of trees and plants by watering and fertilizing can help them recover from cicada damage.

Conclusion

Cicadas may cause damage to plants and trees, but they also play an important role in the ecosystem. By understanding their life cycle and impact on vegetation, we can take steps to manage their damage while still appreciating their unique role in the environment.
