ABSTRACT
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 percent oocyst rates were obtained, in comparison to the 86.67-100 percent 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 percent sporozoite rates were obtained, in comparison to the 85.71-92.31 percent sporozoite rates recovered from An. cracens. An. barbirostris species A1, A2 and A3 were low potential vectors for P. vivax because 9.09 percent, 6.67 percent and 11.76 percent sporozoite rates were obtained, respectively, in comparison to the 85.71-92.31 percent 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 percent and 64.29 percent sporozoite rates were obtained, respectively, in comparison to 90 percent sporozoite rates recovered from An. cracens.
