A transmissão de Plasmodium Gallinaceum pelo Aedes (Ochlerotatus) lepidus

Abstract

Foi pesquisada a capacidade transmissora do Aëdes (O.) lepidus em relação ao Plasmodium gallinaceum. Êste mosquito comportou-se como ótimo vector, apresentando elevado índice oocístico e esporozoítico e produzindo a malária por picada em animais sensíveis (pintos e frangos).<br>The observations reported in this paper indicate that the recently describeb Aëdes (O.) lepidus is a very good vector of Plasmodium gallinaceum, transmitting the malarial infection to chicks of varying ages

Aedes (Ochlerotatus) lepidus (Cerqueira &amp; Paraense, 1945):&nbsp;new record from Mato Grosso do Sul state, Brazil

“…Our new record of Ae. lepidus from Mato Grosso do Sul expands the known geographical distribution of the species, which which has previously been known from the states of Alagoas, Mato Grosso, Minas Gerais, and Rio Grande do Norte (Paraense, 1945;Cerqueira 1957;Xavier et al 1980;Inacio 2016;Andrade et al 2020;Fig. 1).…”

“…Under laboratory conditions, Ae. lepidus presented vector competence to transmit Plasmodium gallinaceum and was used as an experimental model of malaria (Paraense 1945). In an entomological survey carried out in Rio Grande do Norte, Inacio (2016) verified the anthropophilic behavior and crepuscular activity of Ae.…”

“…lepidus. Cerqueira and Paraense (1945) described Ae. lepidus based on adult insects from Belo Horizonte, Minas Gerais (the type locality) and Santana do Ipanema, Alagoas (an additional locality).…”

“…albopictus (Skuse, 1894) were introduced in Brazil and have high epidemiological importance for being as primary or secondary vectors in the transmission of arboviruses (Consôli and Lourenço-de-Oliveira 1994;Martins et al 2013). Aedes lepidus is still poorly understood, and its distribution seems to be restricted to the states of Mato Grosso and Minas Gerais as well as northeastern Brazil (Cerqueira 1957;Paraense 1945;Xavier et al 1980;Andrade et al 2020). We report the first occurrence of Aedes (Ochlerotatus) lepidus (Cerqueira & Paraense, 1945) in Mato Grosso do Sul state, collected from a caveat Templo dos Pilares Municipal Natural Park.…”

A fragment of malaria history

“…After consulting many papers and all existing classification keys I concluded that I had learned a good deal of entomology but was unable to identify the mosquito. It was really a new species -Aedes (Ochlerotatus) lepidus -which I described in collaboration with the entomologist Nelson Cerqueira, of the Rockefeller Foundation (Cerqueira & Paraense 1945), and that thereafter (Paraense 1945) replaced A. aegypti in my experiments.…”
