Probably DDT and/or other pesticides were sprayed liberally and eliminated the anopheles mosquito in those areas. -----Original Message----- From: Scott Monje [SMTP:[log in to unmask]] Sent: Tuesday, November 13, 2001 11:14 AM To: [log in to unmask] Subject: Re: mosquito canopy Speaking of mosquitoes, I've often wondered what became of "Genesee Fever." Settlement of certain parts of western New York was delayed by what the settlers called "Genesee Fever" or "Lake Fever." Later, people determined that this was probably several diseases, including malaria, typhus, and typhoid fever. At some point, the problem seems to have resolved itself, and it's never been clear to me how that happened. Some sources suggest that drainage eventually eliminated the mosquito-borne diseases, but I have trouble with explanations that imply there are no more marshes or mosquitoes in Upstate New York. Can anyone help me with this? Scott Monje
