Figure 3From: Efficacy of long-lasting insecticidal nets in use in Macha, Zambia, against the local Anopheles arabiensis populationITN bioassay survival. ITN survival assays were performed on MIAM An. arabiensis colony mosquitoes and F1 An. arabiensis from the field. Trials with untreated control netting and with deltamethrin-treated netting are shown. There was a small degree of resistance, defined as < 100% mortality at 24 hours, in the F1 field population.Back to article page
