Pest Management Program
Management of larger vertebrate pest species such as coyote, skunk and beaver is conducted under a Merced County contact with USDA-APHIS - Wildlife Services. The Agricultural Commissioner provides indirect oversight of this work.
Biological Pest Management (Biocontrol) in California began in 1888 with the introduction of the Vedalia Ladybettle to control Cottony Cushion Scale on citrus. CDFA, the University of California and County Agricultural Commissioners have been leaders in Biocontrol for over 100 years. In Merced County, Biocontrol agents have been successfully introduced and established for insect pests including Ash Whitefly, Grapeleaf Skeletonizer (3 organisms), and Red Gum Lerp Psyllid. Successful introductions for weed pests include Yellowstar Thistle (5 organisms), Russian Thistle (2 organisms), Puncture Vine (2 organisms), Italian Thistle, and Klamath Weed.
