| Abstract | To provide information for public health policy on mosquito nets in the Amazon region of
Colombia, we conducted landing catches to estimate Anopheles species composition and biting
activity. Two hundred twenty person-nights of catches were done in seven locations over a period
of 14 mo. A total of 1,780 Anopheles mosquitoes were caught (8.1 per person-night). Among the
nine species found, An. oswaldoi Peryassú was the most common (776 mosquitoes, 44%),
followed by An. darlingi Root s.l. (498, 28%). An. oswaldoi was the most common species
collected outdoors, where its biting rate dropped steadily from a peak of >15 bites/person-night at
the start of the night (1800–1900 hours) to ≈2 bites/person-night before dawn. An. darlingi was
the most common species collected indoors, with a biting rate of ≈3–4 bites/person-night until
about midnight, when the rate dropped below 1 bite/person-night, before showing a secondary
peak before dawn. Sixty-four mosquito nets were analyzed by the technique of high-performance
liquid chromatography (HPLC) for levels of deltamethrin (DM). All but two (62) of these were
reported by their owners to have been impregnated with insecticide, and 53 were found by HPLC
to have deltamethrin. However, one half (32) of the nets had concentrations <4 mg/m2 and
therefore were likely to have been inadequately protective. An inverse association was found
between the reported time between washes and deltamethrin concentration. These findings show a
need for additional protection from mosquitoes when not inside nets, as well as for more effective
impregnation, possibly through wash-resistant insecticide formulation. | pt_BR |
