¹Mortality categories

S Susceptible (mortality > 98%)

PR Possibility of resistance (mortality between 80–97%)

R Resistant (mortality < 80%)

Nd Not done

²YES: mean rank of population is significantly higher than mean rank of VHBA An. minimus s.s. population.

NO: mean rank of population is not significant higher than mean rank of VHBA An. minimus s.s. population
