As managers of The U.S. President’s Malaria Initiative VectorLink Project, Abt Global recently published an article in Parasites & Vectors on the malaria vector Anopheles gambiae mosquitoe’s high level of resistance to use of pyrethroid insecticide in Mali. The goal is to understand how PBO nets or next generation long-lasting insecticide-treated nets (LLINs) could provide greater malaria control. The study concluded that “PBO or chlorfenapyr LLINs should provide improved control of An. gambiae (s.l.). Clothianidin, and pirimiphos-methyl insecticides are currently being used for IRS as part of a rotation strategy based on susceptibility being confirmed in this study.”
