Are Raspberries Consumed By Japanese Beetles?

Japanese beetles are an invasive species of scarab beetle that can cause significant damage to fruit crops, including raspberry plants. They are known for destroying many plants at an alarming rate, and understanding what they eat is a great first step in fighting against them. Japanese beetles feed on fruits such as apple, crabapple, grapes, peach, cherry, blackberries, and raspberries, as well as vegetables such as asparagus, corn (foliage and silks), beans, okra, and rhubarb.

Raspberries are one of the most common plants that Japanese beetles feed on, as they feed on the leaves, flowers, and fruits of many types of plants, including raspberries. To get rid of Japanese beetles, growers should try knocking the adults into a container of soapy water, which coats their body, prevents air exchange, and suffocates them. When Japanese beetles eat, they release pheromones, attracting more beetles into the area. The larvae will feed on the roots of the grass, ornamental plants, strawberries, corn, beans, and tomatoes.

To control Japanese beetles on raspberry plants, growers should read the pesticide label and follow their instructions carefully. They can be removed by knocking the adults into a container of soapy water, but it is important to always read the pesticide label to ensure you follow their instructions.

Spotted wing drosophila (SWD) and Japanese beetles are the primary insect pests for raspberries. After removing their main food source, Japanese beetles attack the fruit, causing the leaves of the plants to resemble “lace” and the fruit to be half-eaten and left to rot. To control Japanese beetles on raspberry plants, growers should use a commercial pesticide or a combination of methods to control and kill them without contaminating the fruit.

What Is Eating My Raspberries?

Spotted wing drosophila (SWD) and Japanese beetles are the main insect pests affecting raspberries, with SWD posing the greatest threat as it lays eggs directly into the berries, leading to significant economic losses. Consequently, pest management programs for raspberries focus heavily on SWD.
