Light Brown Apple Moth - UPDATE 3/12/2009

This season has seen high levels of Light Brown Apple Moth caterpillars. Look for any flower parts that are stuck together - above.

How many Apple moth grubs are a problem? Apple Moth caterpillars, cause damage to bunches which makes them much more susceptible to botrytis infection and spread. Also in high numbers, apple moth reduce the yield of your block – which for high value fruit may become an issue.

Check the Program Environmental Impact Report (PEIR) on the CDFA's website. Chapter # 3, pages 3-20 and 3-21. After somewhere between four and 50 years in California, the Light Brown Apple Moth (LBAM) has done NO DAMAGE.

The reports of damage in the media are false. Check with the Agriculture Commissioner's office where media reports have publicized damage and there is NO DOCUMENTATION of DAMAGE. Damage is stated and repeated over and over in the press, but never occurred.

By the way, the USDA has confirmed that even DNA testing for LBAM is still not certain because there are still many California tortricidae moths whose DNA have not been sequenced, so the reference database is incomplete.

And likely LBAM are showing up only as one in 50 to one in 200 of the native moths that are suspect for doing any damage at all.

LBAM has so much publicity because of the story of its "Invasion" that everything gets attributed to LBAM, but in fact, LBAM has been in California for many decades and no damage was attributed to it until CDFA flooded the media with false information, false fear and outright lies about LBAM's biology, capability and damage.

If CDFA, with the assistance of USDA, can initiate and maintain the LBAM eradication program for the average time of their other insect eradication programs, they can more than double their annual general fund budget every year for 30 years and bring approximately $3 billion ADDITIONAL taxpayer dollars into their agency. The overwhelming majority of those funds will end up in service and pesticide contracts going to privileged insider chemical companies, intimately connected to top CDFA Management.

The next time you see any tortricidae moth activity of any kind, is it really LBAM or is it
Omnivorous leafroller: Platynota sultana
Orange tortrix: Argyrotaenia franciscana
Apple Pandemis, Pandemis pyrusana
Fruittree Leafroller, Archips argyrospila
Obliquebanded Leafroller, Choristoneura rosaceana
…all native in California and dozens more.

The only real damage related to LBAM are the quarantines, surprise inspections and the unnecessary pesticides that CDFA is forcing onto growers. When CDFA tasks themselves with "Keeping the Sky from falling," they need to look like they are doing something important/legitimate so that the money they take is not challenged.
