    Abstract:
    BACKGROUND: Limited information is available on malaria vector composition, feeding habits and malaria transmission in northern Malawi. Evidence of mosquito species diversity in this area was established in 2009, when Anopheles funestus-like, a new member of the An. funestus group was described. Additional biological information is needed to identify this species and to understand its role in malaria transmission. METHODS: Anopheline mosquitoes were collected in northern Malawi and analyzed for Plasmodium species infection, blood meal source and susceptibility to insecticides. A new hydrolysis probe assay was designed to identify An. funestus-like. RESULTS: Anopheles funestus and An. rivulorum predominated in the indoor collections. Most An. funestus-like were collected indoors, mainly fed on animals and were uninfected with P. falciparum. Anopheles funestus showed insecticide resistance to deltamethrin and bendiocarb. A high-precision hydrolysis probe assay was successfully developed to identify An. funestus-like. DISCUSSION: Four species in the An. funestus group were collected in Karonga. Resistance to deltamethrin and bendiocarb was observed in An. funestus and further investigation is needed on the insecticide resistance mechanisms. Anopheles funestus-like, while collected indoors, is mainly zoophilic and most likely not a malaria vector. ACCESSION NUMBERS: An. funestus (GenBank accession no. KC771136), An. funestus-like (GenBank accession no. KC771137), An. parensis GenBank accession no. KC771138) and An. vaneedeni GenBank accession no. KC771139).
