| Abundance Projection Immature Mosquito ![]() |
Using a climate-based model for simulating Culex mosquito populations in the Northeast United States, daily estimates of adult and immature mosquito population are presented. Maps show the simulated abundance relative to historical (1979-2008) daily abundance. See Adult Map. |
Moisture ![]() |
Research has indicated that adult mosquitos (Culex) populations are typically high during periods of time when precipitation exceeds evaporation. Negative values indicate that evapotranspiration exceeded precipitation. |
Degree Days ![]() |
Research has indicated that the emergence of adult mosquitos (Culex) typically occurs after the accumulation of 230 base 50�F daily degree days. |
Frost ![]() |
The occurrence of sub-freezing temperatures inhibits mosquito development and activity. A freeze (28�F) represents relatively severe freezing conditions, whereas a frost (32�F) is generally less detrimental to cold-sensitive biological activity. |
