York County Mosquito Control is dedicated to participating in research and development projects that benefit mosquito control in various ways, such as cost effectiveness, increased efficacy, or in developing more green pest control options.
Mosquito Pesticide Resistance Study
Oviposition Cups (Cemetery Urns) have been placed throughout the county to entice mosquitoes to lay their eggs there. Each week a member of the staff collects a piece of paper which has been placed in the cup. The eggs are counted and after 3000 eggs have been collected they are sent of to Va. Tech. The eggs are reared to adulthood and go through several generations. The last generation is bombarded with pesticides to see if the mosquitoes in our area are showing resistance to the pesticide we use.
Mosquito Trap Study
Since 2014, mosquito control staff has been using CDC light traps, gravid traps, BG Sentinel and Faye Prince traps to analyze the numbers and different species trapped. This will provide a more ecological and economical mosquito program. Along with this study we are using state of the art mapping programs to provide us with areas we can target for more precise control.
Mosquito Repellent Plant Study
Since the mosquito season of 2014, staff cultivated over 20 different varieties of plants known for their mosquito repellent qualities. We are currently studying how effective these plants may be when used as personal insect repellents. We are also studying which plant varieties may be most effective in repelling mosquitoes.
We plan to be studying the benefits and uses of these plants for several years. As we compile data, this information will be made available to our citizens.
West Nile Virus Testing
Mosquito Control Division is currently testing local-area mosquitoes for West Nile Virus.
