Article Synopsis
- Culex coronator, a mosquito species first reported in Texas in 1920, has spread to 14 states in the southeastern USA by 2005, with sightings as far north as northern Oklahoma and Virginia.
- * The public health risk of Cx. coronator is not clearly defined, but it has been suggested as a potential carrier for various diseases, making its study important.
- * Recent research has added 146 county-level records of Cx. coronator from several southern states, bringing the total documented presence to 386 counties across 14 states.
Article Synopsis
- Aedes aegypti, a mosquito species linked to diseases like dengue, re-emerged in urban areas of the southwestern U.S.A. during the 1990s after being absent for 40 years.
- A systematic survey in Tucson, AZ, between 2003 and 2004 assessed factors contributing to the mosquito's presence, measuring their abundance using specialized traps during the summer rainy season.
- The study found that the age of houses was the most significant factor influencing mosquito populations, with older homes having more mosquito eggs, signaling a need for further research to aid in mosquito control and disease prevention efforts.
Aedes aegypti, the mosquito responsible for transmitting dengue, has colonized many cities and towns throughout Arizona. Determining both the migration between, and the origin of, local Ae. aegypti populations is important for vector control and disease prevention purposes.

Results: Oocyte growth was nearly linear between adult eclosion and was complete by 72 hours at 21 degrees C. The oocyte became opaque at 14 hours after eclosion indicating the initiation of protein yolk deposition.
