In the present study larvicidal efficacy of methonol leaf extract of Thevetia peruviana was tested against the aquatic stages of Aedes aegypti.

The use of insecticide treated nets (ITNs), and subsequently the new generation of long-lasting insecticide treated nets (LLINs), has been a core malaria prevention strategy for more than two decades, and until 2010, distribution of LLINs targeted biologically vulnerable groups such as pregnant women and children aged less than 5 years.

Following a decade of gains in malaria control, two divergent prospects are emerging: malaria elimination in many endemic countries, and spreading artemisinin-resistant P. falciparum undermining these gains. The potential benefits of malaria elimination are substantial, including the direct burden averted and economic growth through improved educational attainment and productivity; these gains were estimated recently to far outstrip the costs required to achieve them.

West Nile virus infection is a growing concern in Europe. Vector management is often the primary option to prevent and control outbreaks of the disease. Its implementation is, however, complex and needs to be supported by integrated multidisciplinary surveillance systems and to be organized within the framework of predefined response plans. The impact of the vector control measures depends on multiple factors and the identification of the best combination of vector control methods is therefore not always straightforward.

From dogs to balloons, researchers are using unorthodox ways to find out where malaria vectors hide during a long dry season.

It has been theorized that inducing extreme reproductive sex ratios could be a method to suppress or eliminate pest populations. Limited knowledge about the genetic makeup and mode of action of naturally occurring sex distorters and the prevalence of co-evolving suppressors has hampered their use for control. Here we generate a synthetic sex distortion system by exploiting the specificity of the homing endonuclease I-PpoI, which is able to selectively cleave ribosomal gene sequences of the malaria vector Anopheles gambiae that are located exclusively on the mosquito’s X chromosome.

The present analysis included 381 women enrolled in the Study of Women and Babies (SOWB) during 2010–2011, from eight South African villages in the Limpopo Province, South Africa. Indoor residual spraying (IRS) occurred in half of the villages. Questionnaires regarding various demographic and medical factors were administered and blood samples were obtained.
