Belated May Mosquito Report

One of the fun things we get as Mayor and Trustee are reports on Mosquitoes! Here is the most recent one I have from May! Its actually interesting, but then again I like reading stuff like this!

SURVEILLANCE & WEATHER

The rainfall total for the month of May to date (0.72in.) is about an inch and a half a below the average for May to date (2.28in.) Across most of the northern part of the state, precipitation averages have been average since January. However, due to the recent lack of rainfall, we are likely to experience drought conditions. Increased temperatures with little rainfall create ideal conditions for Culex mosquitoes which are potential carriers of West Nile Virus.

Brood Prediction
The floodwater mosquito, Aedes vexans, is the key nuisance species in the Chicago land area. Distinct hatches of floodwater mosquito populations, or broods, are triggered by significant rainfall events. The Clarke Brood Prediction Model calculates peak annoyance periods based on rainfall and temperature data collected from weather stations in your area.

OPERATIONS SUMMARY

Upcoming June Operations:

1 Complete Inspection

1 Targeted Inspection

RECOMMENDATIONS
The CDC currently shows a risk category 1. Conduct entomological survey (inspections) and surveillance to monitor larval and adult mosquito density; Maintain vector and virus surveillance; Expand community outreach and public education programs focused on risk potential and personal protection emphasizing residential source reduction.
