BACKGROUND & OBJECTIVES Identification of novel effective larvicide from natural resources is essential to combat developing resistances, environmental concerns, residue problems and high cost of synthetic insecticides. Results of earlier laboratory findings have shown that Calotropis procera extracts showed larvicidal, ovicidal and refractory properties towards ovipositioning of dengue vectors...

Although the zika virus (ZIKV) has now been strongly correlated with emerging cases of microcephaly in the Americas, suspicions have been raised regarding the use of pyriproxyfen, a larvicide that prevents mosquito development, in drinking water. The effects of this compound on neurodevelopment have not yet been addressed specifically in vertebrates. As a result, we aimed at addressing the effe...

In the northern suburbs of Chicago, stormwater catch basins are the primary source of vector mosquitoes targeted by the local mosquito abatement district, and therefore effective catch basin larvicides are needed. From June to September 2011, Natular XRT was applied at label rate to a cluster of 20 catch basins and compared to a cluster of 20 untreated basins all within a small 0.21 km2 area of...

A successful attempt of using sodium salt of a water- insoluble larvicide, as an alternative to the use of solutions of such larvicides in acetone and water, for the larvicidal studies is made, in the present study biochanin - A an isoflavone isolated from the flowers of Dalbergia sissoides (grah) when assessed for larvicidal study as its sodium salt on the fourth instar larvae of Culex quinque...

In a quarter-mile horse, tumor-like mass was presented on the left flank, with diagnosis of sarcoid. At beginning, cures were carried out twice day natural water, hydrogen peroxide and coumaphos propoxur as mosquicide larvicide, observing that there no favorable regeneration tissue after surgical removal tumoral mass. Treatment NANOCIT initiated 16th surgery, spray citrus extracts adsorbed to t...

BACKGROUND Vector and malaria parasite's rising resistance against pyrethroid-impregnated bed nets and antimalarial drugs highlight the need for additional control measures. Larviciding against malaria vectors is experiencing a renaissance with the availability of environmentally friendly and target species-specific larvicides. In this study, we analyse the perception and acceptability of spray...

BACKGROUND Malaria still remains a public health problem in Iran. There are different vector control interventions such as insecticide spraying. The present study was carried out to determine the susceptibility status of Anopheles stephensi larvae to temephos as a national plan for monitoring and mapping of insecticide resistance. METHODS Eight different localities in two main malarious provi...
