Subject: Questions about the Bandon Mosquito Press Release
Hello Mrs. Zogg,
I have read the county's Health Advisory Press Release concerning the Bandon Marsh mosquito problem and I have few questions about your Department's findings.
http://www.co.coos.or.us/Portals/0/Public%20Health/Documents/Bandon_Mosquito_PressRelease.pdf
Who or what entity is to blame for the mosquito problem?
Without a vector control program in place, where mosquito surveillance (i.e., trapping, speciating, monitoring for disease) would be an integral part of the program, it is difficult to say who or what singly entity is to blame. We do believe that the majority of the mosquitoes in and around the Bandon Marsh area are coming from the section of the marsh that is in the process of being reclaimed.
Was the first phase of the Bandon Marsh expansion in September of 2011 and the removal of the tide gates the cause of the mosquito breeding ponds, which created the mosquito infestation?
From what I understand, the efforts made to reclaim the Bandon Marsh have resulted in the creation of habitat that promotes the life cycle of theAedes dorsalis, the species that is currently most prevalent in the area.
If the tide gate removal were the cause then wouldn't spraying the mosquitoes be treating the symptoms and not a fix to the problem?
You are correct. By spraying we'd only be fixing the current problem. An integrated vector (mosquito) control program will be most effective at addressing the short-term and long-term problem. That being
said, once the marsh is back to its natural state, the explosions of the mosquito population will occur less frequently because there will be natural drainage systems put back into the marsh.
Would you recommend that the US Fish & Wildlife Service replace those gates as a permanent solution to what will become an annual mosquito infestation?
This is not may area expertise and I do not know what was done prior to control the mosquito population. From what I do know about this particular mosquito, Ae. dorsalis, this problem could be addressed in two ways: 1) return the land to the previous state or 2) return the land to its natural state. From what I have learned about this species of mosquito, the eggs are laid on the soil by the adult mosquito and are activated by the flooding of brackish (tide) water. This flooding can be controlled/prevented by gates or natural drainage systems built into the marsh. In addition, with monitoring by a vector control program, larvacides (natural or chemical) could be put into the water to decrease the amount mosquitoes progressing to the adult stage.
Didn't the Army Corp of Engineers install those tide gates in the early 1900's to stop the mosquito problem in the first place, because without the tide gates the reseeding tides left stagnate ponds, which became fertile breeding grounds for malaria caring mosquitoes?
I am not aware of what the motives were to install the tide gates.
If your Department recommends spraying will it stop the next several years of infestation or will the county have to spay every year from here on out?
No, spraying this year would not stop the next several years of infestation; however, we would not recommend spraying every year from here on out. Rather, if a vector control program is put in place, then spraying should not be necessary because as part of a solid vector control program, surveillance and control measures are put in place to mitigate these types of situations from occurring. However, it is unknown at this time if a vector control program will be supported by the County Commissioners and community.
Do these sprays have the potential of harming humans?
Any time a chemical is being introduced into an area where animals and people exist there is a potential risk to health that needs to be considered.
Could you name the other 5 species of mosquitoes?
The five mosquitoes that have been identified in the Bandon Marsh include:Aedes dorsalis, Culiseta particeps, Culex tarsalis, Culex pipiens and Ochlerotatus sticticus.
Thank you for your time and could you please send your reply to the Bandon City Manager and Commissioner Bob Main?
