So, we only compute in comparison between the proposed algorithm and EGVM
. We illustrate the results for four parameter sequences [[alpha].sub.n] = 1/[(n+1).sup.p], [[beta].sub.n] = 0.5(1 - [[alpha].sub.n]), p =1, 0.7, 0.5, 0.1 and two stepsizes [[lambda].sub.n] = 1/5[c.sub.1] or [[lambda].sub.n] = 1/2.1[c.sub.1].
The eradication of EGVM
in the North Coast of California, achieved in 2012, is an outstanding example.
UC and the regulatory agencies have worked together on many cases of invasive pests and pathogens, including the Asian citrus psyllid/huanglongbing complex, EGVM
, diaprepes root weevil, light brown apple moth, red imported fire ant, glassy-winged sharpshooter/Pierce's disease complex, Mediterranean fruit fly, palm weevils, polyphagous shot hole borer, foot and mouth disease, BSE, avian influenza, exotic Newcastle disease, anthrax, bovine tuberculosis, equine herpes myeloencephalopathy, livestock toxicosis, bovine brucellosis and both land and aquatic invasive plants.
On October 7, 2009, USDA confirmed the presence of EGVM
in Napa County.
These regulations are designed to reduce the risk of EGVM
larvae moving off conveyances holding infested fruit and the potential risk that viable larvae could exist in green waste and overwinter as pupae.
Logistics: A quarantine area was formed for EGVM
in Santa Cruz County.
"However, while celebration of accomplishments to date is important, we must remain vigilant in the year to come and not give up before we have reached our goal: elimination of EGVM
from Napa County and the state of California."
Logistics: The area remains free of EGVM
with restricted movement of grapes into region.
populations, Whitmer said, "were very high in some vineyards during the 2009 harvest." He termed it likely that EGVM
had spread from the first infested areas to other locations "before we established regulatory controls and initiated an aggressive pest management strategy."
-- Due to continued pressure from the invasive and destructive European grapevine moth (EGVM
), Napa County agricultural commissioner Dave Whitmer warned growers and wineries that they will not be allowed to harvest, move or receive winegrapes without a compliance agreement issued by his office.
Napa, Calif.--The International Technical Working Group for the European Grape Vine Moth (EGVM
) in California issued its final report after meeting in Napa recently.
