Staggered larval time-to-hatch and insecticide resistance in the major malaria vector Anopheles gambiae S form

Malaria Journal

Table 3 Mean percentage mortalities of PBO, TPP or DEM synergized and unsynergized samples of 2-5 day old Anopheles gambiae laboratory colony (GAH) females 24 h post exposure to listed insecticides (syn = synergized; unsyn = unsynergized. Bolded p-values are significant at 95% confidence intervals).
