Fig 3. Field evaluation of Spinosad (NatularTM DT) against Aedes aegypti 3rd instar larvae.
The average mortality percentage is represented for three independent bioassays conducted in a row, A- Rockefeller, Marilia and Salvador (tested between July 2011 and February 2012). B- Rockefeller, Goiânia and Santarém (tested between September 2011 and November 2012). C- pH and temperature of the solution in the tanks during the three assays for the Rockefeller, Marilia and Salvador group. D- pH and temperature of the solution in the tanks during the three assays for the Rockefeller, Goiânia and Santarém group. The dose tested was 0.5mg/L. Every week the tanks were recolonized by removing the dead and the remaining living larvae and introducing 30 new 3rd instar larvae.
