RESUMO
Antibodies against the Plasmodium vivax-like/P. simiovale malaria parasite circumsporozoite repeat peptide (APGANQEGGAA)3 were determined by enzyme-linked immunosorbent assay (ELISA) in 120 sera randomly collected in 1994 from adults in 3 localities of the malaria endemic area in the State of Acre, Brazil; antibody was detected in 18 (15%). A 'sandwich' ELISA using monoclonal antibody (mab) Pam 172, directed against the same peptide, was carried out on 1207 Anopheles oswaldoi, 12 of which (1.0%) were positive, and 168 A. deaneorum, 2 of which (1.2%) were positive. This is the first report of serological detection of the P. vivax-like parasite in anophelines and the first report linking anopheline to human serology for this parasite in the same geographical area. It is an additional indication that A. oswaldoi is a malaria vector in Acre.

Larvae of Aedes albopictus from a plant of the Bromeliaceae family on the outskirts of S. Paulo, SP, Brazil, were collected. This occurrence sheds new light on the attempt to determine the potential of this plants as a breeding site for this mosquito in Brazil.
