While the mosquito population is currently low during this low-water year, the Owens Valley Mosquito Abatement Program crew is daily treating pastures and lake areas in preparation for the peak August/September mosquito season.
OVMAP Manager Chris Wickham said the crew has been applying larvicides to pasture areas adjacent to Bishop, Big Pine, Lone Pine and Independence as well as in the Owens Lake area near Keeler since March.
â€śAnywhere we find mosquitoes breeding near human populations is our highest priority,â€ť he said.
Wickham said his crew hasnâ€™t started using adulticide yet. â€śThat is typically done when larva cannot be controlled and there is a threat of disease.â€ť That threat is determined by the number and species of mosquitoes present â€“ in excess of 25 Culex tarsalis mosquitoes, the â€śmost competent vector of West Nile Virus,â€ť per trap.
