RESUMO
A mosquito capture program was initiated to study mosquito species and their potential for arboviral transmission in the Peruvian Amazon. More than 35,000 mosquitoes of 13 different genera and at least 25 species were captured in urban and sylvan sites in the Iquitos area. These findings represent the first published list of Peruvian mosquitoes since 1971 and the first such list from the Peruvian Amazon.

Anopheles mosquitoes captured in Andoas, Peru, a Plasmodium vivax-endemic area in the Peruvian Amazon region, contained both VK210 and VK247 P. vivax circumsporozoite (CS) proteins. Approximately 0.9% of the 4,403 mosquitoes tested by enzyme-linked immunosorbent assay were positive; 28% and 72% of the positive mosquitoes contained VK210 and VK247 CS proteins, respectively. These findings correlate strongly with a recent report of the presence of antibodies in residents of this area that recognize the VK210 and VK247 repeats, clearly indicating that both P. vivax CS protein polymorphs are common in the region.

This article describes a classical dengue outbreak caused by dengue serotypes 1 and 4 that occurred from March to July 1990 in the city of Iquitos and surrounding areas of Loreto Department in the Peruvian Amazon. Epidemiologic data indicate that more than 150,000 persons may have been affected in Iquitos alone. Another dengue outbreak occurred in Tarapoto, a city in the neighboring department of San Martín. Laboratory data indicate that the same dengue serotypes were involved in both outbreaks. No cases of dengue hemorrhagic fever/shock syndrome appear to have occurred. Prior to this outbreak, no indigenous dengue cases had been documented in Peru.

A literature review and compilation of the tick specimens found in Peru and now held in the National Tick Collection was carried out to develop a working list of the tick species likely to be found in Peru. Evidence of 44 species (29 Ixodidae, 15 Argasidae), was found; representatives of 40 species are held as reference specimens. This report adds 14 species to the previously published list.
