Nine colonies of five sibling species members of
Anopheles barbirostris
complexes were experimentally infected with
Plasmodium falciparum
and
Plasmodium vivax
. They were then dissected eight and 14 days after feeding for oocyst and sporozoite rates, respectively, and compared with
Anopheles cracens
. The results revealed that
Anopheles campestris
-like Forms E (Chiang Mai) and F (Udon Thani) as well as
An. barbirostris species A3 and A4 were non-potential vectors for
P. falciparum because 0% oocyst rates were obtained, in comparison to the 86.67-100% oocyst rates recovered from
An. cracens. Likewise,
An. campestris-like Forms E (Sa Kaeo) and F (Ayuttaya), as well as
An. barbirostris species A4, were non-potential vectors for
P. vivax because 0% sporozoite rates were obtained, in comparison to the 85.71-92.31% sporozoite rates recovered from
An. cracens.
An. barbirostris species A1, A2 and A3 were low potential vectors for
P. vivax because 9.09%, 6.67% and 11.76% sporozoite rates were obtained, respectively, in comparison to the 85.71-92.31% sporozoite rates recovered from
An. cracens.
An. campestris-like Forms B and E (Chiang Mai) were high-potential vectors for
P. vivax because 66.67% and 64.29% sporozoite rates were obtained, respectively, in comparison to 90% sporozoite rates recovered from
An. cracens.
