BACKGROUND Studies on malaria vectors in the Pantanal biome, Central Brazil, were conducted more than half a century ago. OBJECTIVES To update anopheline records and assess receptivity and vulnerability to malaria transmission. METHODS Five-day anopheline collections were conducted bimonthly in Salobra, Mato Grosso do Sul state, for one year. Indoors, mosquitoes were collected from their restin...

A survey of the Anopheles species of Western Province, Papua New Guinea, was made in April-May 1992. A total of 6,427 specimens was collected from 74 sites within the province using carbon dioxide-baited light traps and larval sampling. Eleven species were identified using morphological characteristics, allozyme analysis, and species-specific DNA probes. These were, in order of prevalence: Anop...

One potential strategy for the control of malaria and other vector-borne diseases is the introduction into wild vector populations of genetic constructs that reduce vectorial capacity. An important caveat of this approach is that the genetic construct should have minimal fitness cost to the transformed vector. Previously, we produced transgenic Anopheles stephensi expressing either of two effec...

Anopheles (Cellia) farauti Laveran sensu stricto adults were subjected to a range of conditions similar to those experienced by trap-collected mosquitoes prior to processing. Squash blots of these specimens were then analyzed using isotopic DNA probes. Freezing and thawing 6 times and dry storage on silica gel in a vacuum desiccator for up to 180 days did not affect the quality of the DNA. Expo...

BACKGROUND The aims of this study was to analysis the current situation of malaria and to find the distribution of anopheline mosquitoes, as probable vectors of the disease, in Qom Province, central Iran. METHODS This study was carried out in two parts. First stage was data collection about malaria cases using recorded documents of patients in the Province health center, during 2001-2008. The...

Tackling the aquatic stages of anopheline malaria vectors is a key element in integrated vector management (IVM) programmes. The first large trials with Bacillus thuringiensis var. israelensis (Bti) as novel biological control agent demonstrated that its impact can be highly effective, but context dependent. To better understand this dependency, there need to answer fundamental questions on mos...
