A Monterey County, Calif., Superior Court judge has lifted a temporary restraining order that had prevented the state from spraying an insect pheromone over an area infested with the light brown apple moth.

Judge Robert O'Farrel lifted the order Oct. 19 after determining the ingredients in the pheromone Checkmate LBAM-F from Suterra of Bend, Ore., did not contain harmful chemicals.

The pheromone, which mimics the scent emitted by female apple moths, confuses the male so he can't find a female with which to mate. If the female doesn't mate, she can't lay eggs.

Citizens in the area had complained that they couldn't determine the ingredients because the company has a patent. They said they were concerned that the inerts were harmful or toxic.

Gov. Arnold Schwarzenneger directed the California Department of Agriculture to immediately resume eradication efforts. He also directed the department to make public the ingredients.

The ingredients in Checkmate LBAM-F are:


(E)-11-Tetradecen-1-yl Acetate

(E,E) -9,11 Tetradecadien-1-yl Acetate

Crosslinked polyurea polymer

Butylated Hydroxytoluene

Polyvinyl Alcohol

Tricaprylyl Methyl Ammonium Chloride

Sodium Phosphate

Ammonium Phosphate



"Governor Schwarzenegger made it very clear that, to the maximum extent possible under U.S. trademark law, the list of ingredients in the product used to eradicate the light brown apple moth should be disclosed to the public," says state agriculture secretary A.G. Kawamura. "The governor supports the public's right to know every ingredient in the product and is confident that full disclosure will confirm what my department, the California Environmental Protection Agency and California Department of Pesticide Regulation established before treatment began that Checkmate LBAM-F is non-toxic to humans, plants, animals and insects."

Treatments will resume and will be applied on the nights of Oct. 24-27, from 8 p.m. to 5 a.m., weather permitting. Notices including these new dates will be mailed to all known addresses in the treatment area by U.S. mail in advance of the treatment.

The light brown apple moth is of particular concern because it can damage a wide range of crops and other plants including grapes, citrus, stone fruit and many others. It is native to Australia. Since the first moth was trapped near Santa Cruz in February, more than 9,500 others have been trapped in 12 counties.
