It's Mosquito Awareness Week!

State Senator Dr. Aisha Wahab has introduced the state resolution (SCR 49) declaring April 13-19 as California Mosquito Awareness Week. This week aims to raise awareness about the importance of mosquito control, mosquitoes and diseases they can transmit.

 

The public relations committee has developed a press release, social media content calendar, and videos in both English and Spanish. These materials are designed to support your outreach efforts and encourage public participation in mosquito control activities. All communication resources can be accessed here: https://members.mvcac.org/pr-resources/mosquito-awareness-week/.


Please contact Meagan Luevano, PR Chair, at meaganl@placermosquito.org if you have any questions.

Request for Participation in Oropouche Virus Vector Surveillance

With the recent emergence of Oropouche virus (OROV) as a potential public health concern in the United States, the American Mosquito Control Association (AMCA) is collaborating with the CDC to collect surveillance data on its primary vector, Culicoides paraensis.


As part of this effort, we are seeking mosquito control districts willing to assist by deploying modified CDC light traps on a weekly basis. This will help us assess the distribution of potential OROV vectors across the country.


We have limited funding available through our grant to support the purchase of traps and other necessary supplies, if needed.


Attached you’ll find:

  • A detailed protocol for the collection, storage, and shipment of biting midge samples
  • Instructions for modifying standard CDC light traps for Culicoides collection
  • A sample data sheet


If your district is able to participate, or if you know of another district or agency that might be interested, please contact Dan Markowski, AMCA Technical Advisor at 662-822-1270 or email at AMCA.TA@mosquito.org.

Glossary of Terms

MVCAC has created a glossary of terms to provide clear and concise definitions of common terms that mosquito and vector control agencies use in public education and outreach efforts. The definitions are intentionally short and use plain language so they are easy to understand and can be translated into other languages. While MVCDs are not required to use the words and definitions below the goal is to have consistency in language across MVCAC and its member agencies.

Send in Tick Program Updates

Dear MVCAC Members,


As part of our ongoing efforts to support tick surveillance and Lyme disease prevention, please remember to provide any updates to your district’s tick programs to Kelly Fuery, who is serving as our representative on the Lyme Disease Advisory Council. You can reach her at kellyl@msmosquito.org


Additionally, please contact DART to grant permission to share tick data with third parties. This collaboration will help strengthen our public health initiatives and contribute to a broader understanding of tick-borne disease risks across California.



Thank you for your attention to this important matter and for your continued support in advancing our vector control efforts.


Best regards,

Conlin
