What Are the Causes of Curling Leaves on Lemon Trees?

Fruittree Leafroller

• Fruittree leafroller (Archips argyrospila) is a flat, green caterpillar with a black head. The insects are the larval stage of moths that appear two weeks later. The female moths lay their eggs on the upper areas of the tree.

Damage

• Fruittree leafroller rolls the flowers and foliage of an infested lemon tree with its silk threads and start to feed inside the resulting small cavities. Caterpillars create these cavities on a daily basis and often pupate inside them.

Control

• Introduce natural predators in trees to control fruittree leafrollers. Fruittree leafrollers are considered minor pests that rarely require chemical control methods.
