The researchers note, “Permethrin susceptibility of tick populations should be monitored from other 4-poster control areas so that guidelines for managing pesticide resistance in the field can be developed.â€įour-poster devices impart selective pressure on tick populations influencing reproduction and natural extinction of species.Event Information Wednesday, March 30, 2022įor the most up-to-date event information visit our Forum FAQ page Therefore, studies like this highlight the need to assess resistance among disease-vector pest populations regardless of pesticide application methods. Furthermore, increasing populations of rodent and mammalian hosts, in addition to warmer temperatures prompted by the climate crisis, allows for disease-carrying ticks to flourish. Lyme disease is the most common vector disease and a primary concern for the general population. Resistance is an ever-present issue among chemical compounds (i.e., antibiotics, antimicrobials, pesticides) used in medicine and agriculture, and threatening the ability to prevent disease outbreaks, such as Lyme disease. The study suggests continuous use of area-wide, 4-poster devices (devices that attract deer and then apply pesticide to their head, ears, and neck) to apply insecticide treatments on deer to control tick populations promotes resistance. ( Beyond Pesticides, July 22, 2021) A new study published in the Journal of Medical Entomology finds black-legged ticks ( Ixodes scapulari) in New York are developing potential resistance to widely used tick-control pyrethroid insecticide, permethrin.
