Do you love growing raspberries in your garden? Raspberry fruitworm can be a major problem for raspberry plants, causing significant damage to the fruit. In this article, we will discuss everything you need to know about raspberry fruitworm and how you can prevent it from ruining your raspberry harvest.

What is Raspberry Fruitworm?

Raspberry fruitworm, also known as Byturus unicolor, is a type of beetle that feeds on the flowers and fruit of raspberries. The adult beetles are small, brownish-black insects that are about 3 mm long. The larvae are white grubs with brown heads and can grow up to 6 mm long. Raspberry fruitworms usually lay eggs in the soil, and the larvae emerge in spring to feed on the flowers and developing fruit of raspberry plants.

How to Identify Raspberry Fruitworm Damage

Identifying raspberry fruitworm damage is crucial to preventing further infestation. The damage typically appears as small, round holes in the raspberry fruit. You may also notice that the fruit is misshapen or has a sunken appearance. If left untreated, raspberry fruitworm can cause significant damage to the fruit, making it unusable.

Preventing Raspberry Fruitworm Infestation

Clean up debris: Remove any fallen fruit, leaves, or stems from around the raspberry plants to reduce the chance of larvae overwintering in the area.
Prune regularly: Prune your raspberry plants regularly to allow better air circulation and sunlight exposure, which can help keep the plants healthy and less attractive to pests.
Use insecticides: Apply an insecticide spray to your raspberry plants when the flower buds start to swell but have not yet opened. This will help prevent the beetles from laying eggs in the flowers.
Cover the fruit: Cover the fruit with fine mesh netting to prevent raspberry fruitworms from laying eggs on the fruit.
