Estudios de infectividad de la especie anopheles albimanus wiedemann, 1820 (Diptera: culicidae)

Abstract

In order to evaluate the infectivity of Anopheles albimanus Wiedemann, 1820 Cartagena strain, malarial infection attempts were performed from human and non-human primates. 67 attempts from naturally infected patients with P. falciparum and 36 with P. vivax were performed. Dissection of salivary glands were made on 654 P. falciparum infected females of which 11.9% were positive for sporozoites. Out of the 93 P. vivax infected mosquitoes examined, 31.2% presented sporozoites. A total of 4 An albimanus infection attempts were done from experimentally P. falciparum infected Aotus monkeys and none of them presented sporozoites. From 14 P. vivax infected Aotus monkeys 75 infection attempts were done; only 5.2% out of 810 dissected salivary glands presented sporozoites. The results obtained suggeated that the above mentioned strain of An. albimanushas low infectivity under laboratory conditions.
