How do ticks become infected with encephalitis?
The egg stage is the first developmental phase of ixodid ticks, lasting from oviposition to larval emergence. Female ticks lay thousands of eggs on the ground after a blood meal, and each egg encapsulates the genetic material and any cytoplasmic components transferred from the adult.. Date latest changes:
BarS flea drops target the earliest developmental phase of the flea, the egg, by delivering a systemic insecticide that circulates in the host’s bloodstream. When a female flea ingests the treated blood, she deposits eggs that already contain a lethal concentration of the active ingredient.. Date latest changes:
