West Nile virus in the United States
As of July 28, 2020, a total of 25 states have reported West Nile virus infections in people, birds, or mosquitoes in 2020. Overall, 17 cases of West Nile virus disease in people have been reported to CDC. Of these, 12 (71%) were classified as neuroinvasive disease (such as meningitis or encephalitis) and five (29%) were classified as non-neuroinvasive disease [visit CDC] [full article].
The Greater Los Angeles County Vector Control District (GLACVCD) launched Mosquito Watch
GLACVCD recently launched its grassroots outreach program, Mosquito Watch. This neighborhood program, facilitated by the District’s Community Liaisons, educates, mobilizes and empowers individuals to take action against mosquitoes as populations and virus activity increase. Individuals can join Mosquito Watch by visiting and taking a pledge to protect their communities [full article].
New study reveals how day- and night-biting mosquitoes respond differently to colors of light and time of day
A University of California, Irvine School of Medicine-led research team studied mosquito species that bite in the daytime, Aedes aegypti and those that bite at night, Anopheles coluzzii. Findings indicate that night- versus day-biting species of mosquitoes are behaviorally attracted and rebelled by different colors of light at different times of day. Mosquitoes are among major disease vectors impacting humans and animals around the world and the findings have important implications for using light to control them [full article].
EPA Webinar - Pests Don't Socially Distance: Back-to-School Challenges and IPM Solutions
While schools have been closed, facility managers are finding that rodents, cockroaches and other pests have been enjoying the run of buildings and defiantly not socially distancing. Over 124,000 K-12 schools with over 55 million students are headed back to colleges and universities. It is critically important that students return to clean, healthy learning environments.Building managers can use this time of unexpected facility closures to conduct extra scouting, cleaning and exclusion work needed to reduce pest pressure through IPM. This webinar will provide detailed information on how to help schools, childcares and universities control pests through IPM strategies. Join the webinar on August 11, 2020, 2:00PM EDT to learn more!
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). Los Angeles County confirmed their first human infections with WNV for 2020. Mosquitoes found near Lake Havasu, Arizona recently tested positive for WNV. Vector control agencies continue to urge the public to take precautions such as applying repellents on exposed skin and getting rid of mosquito breeding sites [more on WNV activity].

Dengue continues to present challenges in the Marshall Islands
Ten additional dengue-like illness (DLI) cases have been reported during the period since the last update. In total there have been 3,500 cases of dengue-like illness (DLI), of which 1,651 have been laboratory-confirmed in the Republic of the Marshall Islands between May 2019 and 21 July 2020. Two deaths were reported since June 2019. The outbreak is reported to be ongoing [Full Article].

Aedes Challenge 2020: More modelers [still] wanted!
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.
