For each row (#, ## and ###), where provided, numbers in the same column (from the same study) sharing a letter superscript do not differ significantly (P > 0.05). For resistance status of An. arabiensis in Tanzania, percentage mortality of 58 and 76 were observed for lambda cyhalothrin and permethrin (both pyrethroids)
