Also, some more primitive species of fish, such as the sturgeon in the Great Lakes are sensitive to chemicals such as TFM.

Notability date May 2011 This is a description of Public health concerns in Onondaga County , New York . History West Nile virus The Vector Control program conducts bird and mosquito surveillance and mosquito control activities in order to prevent transmission of vector borne diseases. In 2009, West Nile virus WNV detected in mosquitoes and birds in Onondaga County. In addition, Eastern equine encephalitis virus EEE virus was detected in mosquitoes. There were no reported human cases of WNV or EEE virus infection in Onondaga County in 2009. The Vector Control program performed mosquito control activities from May through September. Program staff treated 8,300 catch basins throughout the county with Altosid XR, a single application, long lasting, briquette larvicide. Nearly 1,000 known breeding sites were checked and treated, as necessary, with granular larvicide or larviciding oil. The number of treated catch basins was reduced due to the decline in WNV activity in recent years. H1N1 On June 11, 2009 the World Health Organization declared that this virus represented the emergence of the 2009 H1N1 pandemic. Unprecedented levels of influenza activity were documented in Onondaga County. Over the summer and early fall, http www.ongov.net health Onondaga County Health Department , in close partnership with the New York State Department of Health , worked to respond to and prepare for more influenza activity. The OCHD maintained regular communication about the pandemic with health care providers, schools, governmental and community based organizations, and the public throughout the summer and fall. Public health preparedness staff focused efforts on developing a mass vaccination plan, targeting school age children who were both most likely to get the disease and spread the disease. By September 2009, influenza cases started to increase again, ultimately peaking the last week of October. The vaccine started arriving in October and Onondaga County was prepared to deliver it ... more details
other uses An insecticide is a pesticide used against insect s. They include ovicides and larvicide s used against the Egg biology eggs and larva e of insects respectively. Insecticides are used in agriculture , medicine , industry and the household .

Insects ingest the insecticide while feeding on the plants. Contact insecticides are toxic to insects brought into direct contact.

More footnotes date October 2010 File Culiseta annulata from Marshall 1938.jpg thumb right Mosquitos are generally considered annoying and may also transmit diseases, thus leading to a variety of human efforts to eradicate or reduce their presence. Mosquito control manages the population of mosquito es to reduce their damage to human health, economies, and enjoyment. Mosquito control is a vital public health practice throughout the world and especially in the tropics because mosquitoes spread many diseases, such as malaria . Mosquito control operations are targeted against three different problems Nuisance mosquitoes bother people around homes or in parks and recreational areas Economically important mosquitoes reduce real estate values, adversely affect tourism and related business interests, or negatively impact livestock or poultry production Public health is the focus when mosquitoes are Vector epidemiology vector s, or transmitters, of infectious disease . Disease organisms transmitted by mosquitoes include West Nile virus , St. Louis Encephalitis Saint Louis encephalitis virus , Eastern equine encephalomyelitis virus , Everglades virus , Highlands J virus , La Crosse Encephalitis virus in the United States dengue fever , yellow fever , Ilheus virus , malaria and filariasis in the Neotropics American tropics Rift Valley fever , Wuchereria bancrofti , Japanese Encephalitis , chikungunya , malaria and filariasis in Africa and Asia and Murray Valley encephalitis in Australia. General methods Depending on the situation, source reduction, biocontrol, Larvicide larviciding control of larva e , or adulticiding control of adults may be used to manage mosquito populations. These techniques are accomplished using habitat modification, pesticide , biological control agents, and trapping. Monitoring mosquito populations Adult mosquito populations may be monitored via landing rate counts, or mechanical traps. For landing rate counts, an inspector visits a set number of site ... more details
