Peach Tree Borer – Definition & Detailed Explanation – Tree Diseases and Pests Glossary

What is a Peach Tree Borer?

The Peach Tree Borer (Synanthedon exitiosa) is a type of moth that belongs to the family Sesiidae. These pests are known for infesting and causing damage to various fruit trees, with peach trees being one of their preferred hosts. The adult moths are about 1 inch long with clear wings and a metallic blue body. The larvae, which are the damaging stage of the insect, are white with a brown head and can grow up to 1 inch in length.

How to identify Peach Tree Borers?

Identifying Peach Tree Borers can be challenging, as the adult moths are often mistaken for other harmless insects. However, there are a few key characteristics to look out for. Adult moths are typically active during the summer months and can be seen flying around the trunks of trees. The larvae, on the other hand, are usually found inside the tree, tunneling through the bark and feeding on the inner tissues.

What are the signs and symptoms of Peach Tree Borers?

One of the most common signs of a Peach Tree Borer infestation is the presence of sawdust-like frass around the base of the tree. This is a result of the larvae tunneling through the bark and pushing out the wood shavings as they feed. Other symptoms include wilting leaves, yellowing foliage, and gumming or oozing sap from the trunk. In severe cases, the tree may exhibit dieback or even death.

How to prevent and control Peach Tree Borers?

Preventing Peach Tree Borers is key to protecting your fruit trees from damage. One of the best ways to prevent infestations is by maintaining healthy trees through proper watering, fertilization, and pruning practices. Additionally, wrapping the base of the tree with a physical barrier, such as burlap or cardboard, can help deter adult moths from laying eggs. Chemical controls, such as insecticides, can also be used to target the larvae and adults.

What are the potential damages caused by Peach Tree Borers?

Peach Tree Borers can cause significant damage to fruit trees if left unchecked. The larvae tunneling through the bark can disrupt the flow of nutrients and water, leading to wilting, yellowing, and stunted growth. In severe cases, the damage can be so extensive that it weakens the tree, making it more susceptible to other pests and diseases. Ultimately, a severe infestation of Peach Tree Borers can result in the death of the tree.

How to treat Peach Tree Borers infestations?

Treating Peach Tree Borers infestations can be challenging, but it is possible with the right approach. One method is to physically remove the larvae from the tree by carefully cutting away the affected bark and destroying the insects. Another option is to use biological controls, such as parasitic wasps, to target the larvae. Chemical controls, such as insecticides, can also be effective in killing off the pests. It is important to monitor the tree regularly and take action at the first sign of an infestation to prevent further damage.
