Experimental Evaluation of the Residual Efficacy of Sumilarv™2MR, Sumilarv™0.5G, and VectoBac® WDG on Anopheles stephensi larvae in Dire Dawa, Ethiopia

Objectives

The project will answer following questions:

  1. Can long lasting larvicides be used to reduce An. stephensi larval density in locations where invasive populations have established?
  2. Which is more effective against An. stephensi in field conditions?
  3. Which product is longer lasting under semi-controlled conditions?
