Just when you think there couldn’t be more to be said on the moths, a new flurry of arguments crops up.
Two competing pieces out today, both using science to support the pro and cons of aerial spraying for the Light Brown Apple Moth.
In a piece called “Moths and Misinformation”, A.G. Kawamura, secretary of the California Department of Food and Agriculture, addresses misinformation about the CDFA’s aerial spraying program for the Light Brown Apple Moth.
These include claims that the pheromone products are untested, that we are all going to be guinea pigs, that the treatments caused a red tide, poisoned the water, and even killed waterfowl.
And then there are what Kawamura characterizes as, “misleading and inaccurate references to describe a pheromone, including hormone, carcinogen, mutagen, endocrine disruptor and other scary-sounding descriptions.”
“I urge the public to seek out scientific studies and historical data,” Kawamura states.
Meanwhile, Dr. Dennis Knepp and Dr. Jeff Haferman, two Monterey area scientists, claim to have unearthed serious errors in an analysis of the particle size of the Suterra pesticide spray being used to combat LBAM.
We can see how small the moths are, but just how big are the particles in the aerial pheromone spray?
Well, Knepp and Haferman recently reviewed particle-size data from Suterra and provided by CDFA. They claim to have found that the CDFA made serious errors in their review of the Suterra data.
“The CDFA states in their analysis that only 1.2% of the particles in the Checkmate spray were smaller than 10 microns, which is a critical size for inhalation to deep within the lungs.
“They based their computations on particle volume, not number of particles, which is simply incorrect,” Haferman stated. Knepp explained that when the analysis is corrected “we find the average particle size to be about 17 microns with significant numbers of much smaller particles.”
“Our analysis shows that the small particle sizes from the Checkmate spray can cause significant health issues, and the CDFA needs to seriously reexamine their findings” said Knepp.
Knepp has a Ph.D. in Electrical Engineering and has published over 50 peer-reviewed papers in the areas of Geophysics and Electrical Engineering. Haferman has a Ph.D. in Mechanical Engineering, and has published over a dozen papers in the fields of Meteorology and Engineering, and also sits on the Monterey City Council.
