Participate in the PacVec needs assessment by THIS FRIDAY!
Our center is conducting a needs assessment to understand perceived gaps in training and workforce needs relating to vector-borne disease and public health. Information gained from the needs assessment will be used to develop a PacVec short-course training curriculum to meet the needs of vector control and public health agencies and to expand the potential recruitment pool for the vector control workforce. Learn more about PacVec here. Please circulate this needs assessment among your networks within the Pacific Southwest. Participate in the needs assessment by Friday, September 18th, 2020!

Aedes aegypti mosquito detected for the first time in Yolo County, California
The first ever detection of an Aedes aegypti in Yolo County, CA was announced Tuesday, September 15th by the Sacramento-Yolo Mosquito and Vector Control District. “As part of our ongoing surveillance program, we have been setting traps looking for invasive mosquitoes,” said District Manager Gary Goodman. “Finding this mosquito for the first time likely means it could possibly be established anywhere [in the region]. We will continue to work diligently to look for and identify locations where these mosquitoes can be breeding,” emphasized Goodman. [Sac-Yolo MVCD News Release] [News article] [VectorSurv Map]
Update on arbovirus activity in the Pacific Southwest
More mosquitoes from counties across the Pacific Southwest have tested positive for West Nile virus (WNV) and St. Louis encephalitis virus (SLEV).
WNV disease reported:
Idaho's first human WNV infections of 2020 have been identified among two Owyhee County residents. Both residents were over the age of 50.

Washington's first two cases of WNV infections have been confirmed in a Yakima County man in his 50s and a Benton County man in his 60s.

New online training course on vector surveillance methods from eCornell
Learn to develop an effective vector surveillance program, collect data, and communicate risk with the Cornell Entomology Department and eCornell in the newest online course Vector-Borne Diseases Surveillance. Take this 3-week instructor-led course with Dr. Laura Harrington and learn best practices to implement vector surveillance, data, and reporting methods.
Aedes Challenge 2020: Model forecasts invited
UPDATE: Because of the many challenges caused by COVID-19, we have decided to accept forecasts for the Aedes Challenge throughout the remainder of 2020. Interested modeling groups may register at anytime, and forecasts must be submitted before the first day of the month(s) being predicted. See the original announcement below, along with the link to the Aedes Challenge website.
The Centers for Disease Control and Prevention (CDC) Division of Vector-Borne Diseases and the CDC Epidemic Prediction Initiative, in collaboration with the Council of State and Territorial Epidemiologists and the Centers of Excellence in Vector-Borne Diseases, are pleased to announce an open Aedes forecasting challenge for 2020. The Aedes Forecasting Challenge focuses on predicting the seasonal presence of Ae. aegypti and Ae. albopictus in a subset of U.S. counties from multiple states across the country. The challenge is open to anyone and any methodological approach. Further details on how to submit forecasts can be found on CDC's Epidemic Prediction Initiative website. Please disseminate this announcement widely to any modelers who may be interested. Any questions can be directed to
PacVec Resistance Testing
The Kearney Center has transitioned to remote work as a precaution due to the COVID-19 outbreak. This means any requested insecticide resistance testing or workshops will need to wait until normal activities resume. Dr. Anton Cornel and Katherine Brisco will still be available to offer resistance testing support and guidance at this time through email ( or teleconferencing.
Videos on Larval Mosquito Resistance Testing
In collaboration with partners at the Mosquito and Vector Control Association of California, PacVec CoE has produced new training videos providing an overview of resistance testing for larval mosquitoes. The videos discuss the rationale for monitoring resistance in mosquitoes, an overview of dose responses and how the dose response changes as resistance to larvicides evolves in a mosquito population, the different types of larval mosquito control agents, the supplies needed for carrying out bioassays, bioassay set-up and making stock solutions of control agents, and interpreting the bioassay results. See the videos and related materials at
Need Bottle Bioassay Testing?
If you have mosquito (Aedes or Culex) samples to be tested for insecticide resistance, PacVec is providing testing and training services at no charge, and all results will be returned to you. Dr. Anton Cornel's laboratory is leading this activity and organizing various regional training workshops on bottle bioassay testing. If you are interested, please contact us right away at to arrange for shipment and timing of the testing.

Vector Control and Public Health Agencies Need Summer Interns for 2020, or Just Help Advertising Positions for Students?
Please contact us anytime if your agency has seasonal positions that may be of interest to undergraduate students in the Pacific Southwest region. Such positions are important formative experiences for students, and they are excellent opportunities to raise awareness of career opportunities in vector-borne diseases. These can be simple job postings that we will advertise to our undergraduates or we can help you partner with faculty for project-based internships that involve academic credit with a faculty mentor and possible continued data analysis during the school year. If you are interested, please send us a note at To maximize your audience and reach the best candidates for your positions, please send us these position announcements as early as possible, ideally in January or February, before students have settled their summer plans.
