Comparison of experimental infectivity and development of Plasmodium vivax in Anopheles sacharovi and An. superpictus in Turkey.

A study has been made of the infectivity and the sporogenic development of Plasmodium vivax in Anopheles sacharovi and An. superpictus under experimental conditions. An. superpictus showed a slightly lower rate of feeding on human bait, oocyst development, and sporozoite infection of the salivary glands, with ratios of 89.3:100, 89:100, and 98:100, respectively. An. superpictus completed sporogony in 10-14 days with an average of 11.7 days, and An. sacharovi within 8-12 days with an average of 9.8 days. The survival of infected An. superpictus averaged 16.5 days postinfection while An. sacharovi averaged 11.6 days. Under laboratory conditions, An. sacharovi was a more competent vector of P. vivax than An. superpictus.
