New study: Response of small mammal and tick communities to a catastrophic wildfire and implications for tick-borne pathogens
Fire has been used for centuries to shape landscapes, manage woodland, and to consume leaf litter, ground, and shrub vegetation, in order to reduce flammable biomass and provide a favorable substrate for biodiverse seedling regeneration. However, wildfires are typically much more intense than intentional or prescribed burns and can have considerable and lasting impacts on the environment as well as the economy and human health. Wildfires may impact pathogen, vector, and host interactions, leading to changing risks of vector-borne disease in humans and other animals. Despite established risks for tick‐borne disease and increasing frequency and severity of wildfires in the United States, impacts of wildfire on ticks and tick‐borne pathogens are understudied. In 2015, the large Wragg fire extensively burned a long‐term field site at Stebbins Cold Canyon University of California Reserve. In this new study, PacVec investigator Dr. Janet E. Foley and the UC Davis research team characterized the tick, reservoir host and pathogen community over a two-year period after the burn, comparing the findings to pre‐fire data and to data from Quail Ridge Reserve, a nearby unburned site [full article].
Update on arbovirus activity in the Pacific Southwest
Mosquitoes from counties across the Pacific Southwest have continued to test positive for West Nile virus (WNV) and St. Louis encephalitis virus (SLEV). WNV & SLEV disease reported:
The CDC Rickettsial Zoonoses Branch is starting a new MALDI-TOF Tick ID project

The Rickettsial Zoonoses Branch at the Centers for Disease Control and Prevention is partnering with various national and international universities and public health agencies to develop a robust, protein-based platform for identification and characterization of tick species of medical and veterinary importance, with applications for surveillance and scientific activities in the United States and other countries in the Western Hemisphere. We are currently seeking collaborators to provide recently collected (2017- present), field-caught specimens of Amblyomma americanum, Amblyomma maculatum, Dermacentor variabilis, Dermacentor andersoni, Ixodes scapularis, and Ixodes pacificus. We are requesting samples of all feeding life stages of these species from various US locations for subsequent proteomic analysis. Desired specimens should be preserved in 70-95% ethanol and stored at room temperature since the time of collection. Ideally, at least 10 specimens from each geographical location are requested.
If you have questions or can assist with this project please contact Maria Galletti (, Joy Hecht ( or Chris Paddock ( for more information.
Response requested for the second nationwide assessment of local vector control organizations

The National Association of County and City Health Officials (NACCHO), in collaboration with the Centers for Disease Control and Prevention (CDC), will administer the second nationwide assessment of local vector control organizations in the United States to inform CDC funding of state and local vector control programs, and to determine how NACCHO can best provide targeted guidance and training opportunities for local agencies. Starting September 2020, NACCHO will be reaching out to every vector control program in the country to confirm the point of contact for the assessment. For additional information, visit NACCHO’s vector control webpage, or contact
Virtual Tick IPM Special Session
The IPM Institute of North America’s Tick IPM Working Group, in collaboration with the TickEncounter Resource Center and One Health Lessons, will be hosting a virtual Tick IPM Special Session Thursday, December 10 from 1:00-2:30pm CDT. Tick species and tickborne diseases of medical importance are increasing in number and geographic distribution and generating enormous societal costs in lost productivity and treatment expense. During this virtual event, participants will learn from and be able to ask questions of world-class experts about tick IPM during the COVID era and natural repellants – do they actually work?

TODAY (December 10th) from 1:00-2:30pm CDT | 11:00-12:30pm PDT | 2:00-3:30pm EDT

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.
