Observations on the biting activity of Anopheles triannulatus bachmanni from the Mato Grosso, Brazil

Abstract

Anopheles triannulatus bachmanni biting man were collected at Aripuana, Mato Grosso. In paired catches less than 5% of t he insects were coliected biting inside houses, most insects were collected at the edge of the r a in forest at sunset . Physiological ::~ge determination indicated an even age distribution in the females but the insects flight behaviour would make !t of little importance as a vector of mataria .

Population dynamics and spatial structure of human-biting mosquitoes, inside and outside of houses, in the Chockwe irrigation scheme, southern Mozambique

“…In the case of Massavasse, and presumably in similar villages, the high-risk areas were at the edge of the village. Edges are known to be areas of high density for insects as well as for mosquitoes (Bidlingmayer and Hem, 1981;Charlwood and Wilkes, 1981). This may be due to the edge being closer to the sites where the adult mosquitoes first emerge.…”

Molecular divergence in the timeless and cpr genes among three sympatric cryptic species of the Anopheles triannulatus complex

“…is considered zoophilic in most of its territory, it may bite humans indoors and close to houses. It is believed to be a malaria vector when at present at high population densities (Charlwood & Wilkes 1981, Rubio-Palis 1994. Natural infection by Plasmodium falciparum and Plasmodium vivax s.l.…”

Biological variation in Anopheles darlingi root

“…Many insects tend to fly close to the edge of high vegetation rather than disperse over the adjacent open ground. In areas of cleared forest it is possible that the mosquitoes track along the edge of the forest margin (Charlwood & Wilkes 1981) and fly up and down the road. This would enhance contact with humans rather than alternative hosts.…”
