The difference in response to permethrin exposure between blood-fed and unfed cohorts from the Fumoz-R strain was highly significant (p < 0.001) with the blood-fed cohorts showing a mean percentage mortality approximately five times lower than that of the unfed cohorts (Table 1 ).
This finding may be significant in terms of the methods used to control indoor resting populations of An. funestus if the mass killing effect of insecticide application proves increasingly inadequate against blood-feeding females already carrying the insecticide resistance phenotype. status released display-pdf yes is-olf no is-manuscript no is-preprint no is-journal-matter no is-scanned no is-retracted no Received 2008 Jun 19; Accepted 2008 Oct 31; Collection date 2008.
