Strong-arm leaf-feeding Insects


Leaf-feeding insects like Japanese beetles, are one of the most common ornamental pests you might encounter in an outdoor nursery operation. This pest can cause severe damage if left unchecked, leaving plants largely unsaleable.

Active in most areas of the country from late May through August, Japanese beetles are indiscriminate when it comes to food sources and are known to feed on more than 300 different types of plants, trees and shrubs. The beetles will also feed on flowers and fruits, chewing small holes in the leaves, creating a “skeletonized” appearance. In ornamental nursery environments, plan to make early insecticide applications in the spring to reduce pest pressure in the summer when adult beetles can cause the most damage.
