Malaria is considered a major health problem in Iran. There are different methods for vector control. In this study we tested the larvicidal effects of some Iranian plants. The methanolic extracts of 11 plants were prepared with percolation method. The larvicidal activities of them against malaria vector, Anopheles stephensi were studied using World Health Organization standard method. All LC50...

BACKGROUND Plant extracts and oils may act as alternatives to conventional pesticides for malaria vector control. The aim of this study was to evaluate the larvicidal activity of essential oils of three plants of Apiaceae family against Anopheles stephensi, the main malaria vector in Iran. METHODS Essential oils from Heracleum persicum, Foeniculum vulgare and Coriandrum sativum seeds were hyd...

BACKGROUND Anopheles mosquitoes are an important group of arthropods due to their role in transmission of malaria. The present study was conducted for determination of susceptibility status of Anopheles stephensi to different imagicides collected from malarious area in Chabahar city, Iran. METHODS In the present study seven insecticides including: DDT 4%, lambdacyhalothrin 0.05%, deltamethrin...

CONTEXT Insecticide-treated bednets reduce malaria transmission and child morbidity and mortality in short-term trials, but this impact may not be sustainable. Previous investigators have suggested that bednet use might paradoxically increase mortality in older children through delayed acquisition of immunity to malaria. OBJECTIVES To determine whether adherence to and public health benefits ...

Strains of Serratia marcescens, originally isolated from the gut lumen of adult female Anopheles stephensi mosquitoes, established persistent infection at high rates in adult A. stephensi whether fed to larvae or in the sugar meal to adults. By contrast, the congener S. fonticola originating from Aedes triseriatus had lower infection in A. stephensi, suggesting co-adaptation of Serratia strains...

The leaf extract of Agave sisalana was tested as a larvicide against three vector mosquito species viz., Anopheles stephensi, Culex quinquefasciatus and Aedes aegypti. Preliminary results showed that the 2% dilution of the leaf extract produced 100% mortality of IIIrd instar larvae of An. stephensi and 1% dilution produced 100% mortality in case of Cx. quinquefasciatus and Ae. aegypti. For furt...

Environmental concerns have resulted in the search for environmentally friendly natural oils for use as mosquito larvacide. Methylated coconut oil (MCO) has been found to be toxic to mosquito larvae. However, the use of MCO is limited by resource constraints in rural communities in Papua New Guinea (PNG). In PNG and other Pacific Island countries, coconut oil is produced using traditional metho...

Secondary metabolites obtained from the indigenous plants with proven mosquito control potential can be used as an alternative to synthetic insecticides under the integrated vector control. The essential oil extract from the forest redgum, Eucalyptus tereticornis Sm. (Myrtaceae) was tested against mature and immature mosquito vector Anopheles stephensi Liston (Diptera) under laboratory conditio...
