An increased international effort to reduce the incidence of malaria around the globe while reducing reliance on DDT was announced 6 May 2009 at the fourth meeting of the Conference to the Parties to the Stockholm Convention on Persistent Organic Pollutants (POPs). With funding of more than US$70 million, the United Nations Environment Programme and the World Health Organization have launched 1...

The objective of this work was to monitor the susceptibility of malaria vectors to insecticides in nine sentinel sites of the National Malaria Control Program in Mali. The study was performed during the rainy seasons of 2010 and 2011. WHO bioassays were conducted using F0 and/or F1 from wild collected females. The insecticides used were lambda-cyhalothrin 0.05%, DDT 4%, permethrin 0.75%, deltam...

An entomological survey conducted in 2002 in Guinea Bissau aimed i) to study the distribution of the members of Anopheles gambiae Giles complex (Diptera: Culicidae) throughout four ecological areas extended from mangrove to savannah ii) to evaluate the insecticide susceptibility status of these malaria vectors exposed to permethrin 0.75% and DDT4%, and finally iii) to investigate the occurrence...

INTRODUCTION The aim of this study was to evaluate the susceptibility to insecticides of An. gambiae mosquitoes sampled in Dielmo (Senegal), in 2010, 2 years after the implementation of Long Lasting Insecticide-treated Nets (LLINs) and to report the evolution of kdr mutation frequency from 2006 to 2010. METHODS WHO bioassay susceptibility tests to 6 insecticides were performed on adults F0, i...

Metal exposure is one of the commonest anthropogenic pollutants mosquito larvae are exposed to, both in agricultural and urban settings. As members of the Anopheles gambiae complex, which contains several major malaria vector species including An. arabiensis, are increasingly adapting to polluted environments, this study examined the effects of larval metal exposure on various life history trai...

BACKGROUND Previous studies of DDT and breast cancer assessed exposure later in life when the breast may not have been vulnerable, after most DDT had been eliminated, and after DDT had been banned. OBJECTIVES We investigated whether DDT exposure in young women during the period of peak DDT use predicts breast cancer. METHODS We conducted a prospective, nested case-control study with a media...

with regard to the importance of determining the susceptibility level of sandflies to insecticides in control operations especially in leishmaniasis foci, the susceptibility status of p.papatasi collected from indoors in several villages in the rural districts of varzaneh and borkhar, isgahan was tested against 4.0% ddt following a standard who technique during 1991-92. these species is the mai...
