Management of the Leaffooted
Plant Bug
The leaffooted bug is a sporadic pest in almonds. It has been found to use needle-like mouthparts to bore into the almond hull and feed on the kernel. The damaged kernels can then cause the nut to abort, or result in a harvested nut with a black stain. This can reduce both yield and quality of the crop.
A study in Kern County found that leaffooted bug damage in almonds is almost exclusively caused by adult bugs in the spring that migrate into the orchard. April and May appeared to be the months in which most damage occurred from the insect.
Leaffooted Plant Bug Advisory
March 26, 2010 - Monitoring for leaffooted bug should start in orchards which have a history of previous activity and damage. Reports from the Southern San Joaquin show adults have migrated from their overwintering sites and the first bugs have been seen in almond orchards.
