BACKGROUND In the Guadeloupe and Saint Martin islands, Aedes aegypti mosquitoes are the only recognized vectors of dengue, chikungunya, and Zika viruses. For around 40 years, malathion was used as a mosquito adulticide and temephos as a larvicide. Since the European Union banned the use of these two insecticide molecules in the first decade of the 21st century, deltamethrin and Bacillus thuring...

Three onchocerciasis vectors are recognized in Guatemala: Simulium ochraceum, Simulium metallicurn, and Simulium callidum (1); but the most important species is S. ochraceum. Its larvae generally breed in streams that carry a small volume of water and run under a canopy of dense vegetation, but that move swiftly because of the steep slopes of the foothills through which they fall. The larvae oc...

The best way to control mosquito borne diseases is to control the mosquito population. The present study was executed to evaluate the mosquito larvicidal activity of Nicotiana plumbaginifolia leaves against malarial vector Anopheles stephensi.Crude extracts and three different solvent extracts were bio-assayed against An. stephensi larvae. LC50 and LC90 values were determined appropriately. Qua...

OBJECTIVE Evaluating the larvicidal activity of two ether factions from Asteraceae (the aster, daisy or sunflower family, i.e. Heli opsisoppositifolia (L.) Druce (oxeye, sunflower-like) and Jaegeria hirta (Lag.) Less (weed-like)) on Aedes (Stegomyia) aegypti (L.) final third instar or initial fourth instar larvae near the town of Armenia in the Quindío Department in Colombia. METHODS H. oppos...

Effectiveness in controlling mosquitoes in storm water catch basins in the North Shore Mosquito Abatement District (northeastern Cook County, Illinois) was determined for 3 formulations of methoprene-based larvicides (Altosid XR 150-day Briquets, Altosid 30-day Pellets, Altosid 30-day Granules) in 2017 using a pass/fail evaluation criterion, in which emergence of a single adult from pupae colle...

The expanding distribution of the Aedes albopictus mosquito (also known as Asian tiger mosquito) throughout Europe is a health and safety threat due to its potential spread tropical sub-tropical arboviruses temperate climate regions. Therefore, it becoming increasingly important broaden use all tools within integrated pest management systems control this threat. Since species in breeds mainly m...
