The best way to Control Leafrollers on Fruit Trees

The caterpillars of the majority of species in the Tortricid moth family conceal within while they feed and retract leaves using their powerful silk. The insect is benefited by the conduct by shielding it but is of no advantage to the host plant. In huge figures, leafrollers can completely defoliate a tree in one time. Adult moths lay their eggs in drop on easy bark surfaces. The eggs overwinter and hatch in spring. Caterpillars develop and feed through the summer, then pupate and become adults. Different species of leaf roller are pests to various nut, fruit and ornamental trees. The Light Brown Apple Moth, a non native leaf roller, threatens over 1 1000 various plant species in the state and lately invaded California. With prey to beetles, lacewings and parasitic wasps, and only one generation per year, control of leafrollers in your fruit trees is at your fingertips.

Spray the tree using an insecticide. This bacterium kills the soft-bodied caterpillars, but is safe for other organisms and crops.

Look for egg masses in late fall or early spring on the tree-bark as well as in the joints of branches.

Brush or scrape the eggs and dump them not even close to crops that are vulnerable.

Lacewing eggs in springtime on the foliage of the fresh fruit tree. The larvae eat equally eggs and little caterpillars as they hatch.

Release tricogramma wasps at the first indication of moths. These moment wasps lay their eggs in the eggs of other bugs, decreasing or removing the need for leafroller control time.
