Abstract

Malaria sporozoite rates and inoculation rates were measured over periods up to 25 months in the different anopheline species biting humans in 13 villages in Madang Province, Papua New Guinea. Analysis of three members of the complex, 68,458 , 36,779 , and 11,667 caught in landing catches was made using monoclonal antibody based ELISAs to detect sporozoites of and . Sporozoite rates ranged from 0%–5.5% in , 0.2%–3.8% in , and 0%–3.3% in . In addition, over 3,000 were analyzed and sporozoites were not detected in this species. No significant differences were observed between the three vector species in the densities of sporozoites (geometric mean 2,320). However, the geometric mean sporozoite density was significantly higher in (350) than in either (160) or (150). was less susceptible to infections of or than either or .

Variations in average sporozoite and inoculation rates were found among different villages, despite their close geographic proximity. Sporozoite and inoculation rates varied greatly within a village over time, but malaria transmission was perennial with a higher transmission during the wet season by and .
