  • Mosquitoe, Pest Control, Service, Tips Comments Off on Study Reveals That Mosquitoes Carrying Zika Virus Are Resistant To Pyrethroids

    There are more than 3,500 species of mosquitoes all over the world and more than 300 can be found in Australia. In order to protect a person from the diseases that are carried by mosquitoes, people purchase insect repellents or mosquito nets.A very good option is Mozzie band in Australia, a silicon-based wristband that keeps away mosquitoes, sand flies, midges and insects.

    According to a new study made by scientists of the US Department of Agriculture, mosquitoes that carry Zika virus and other diseases are resistant to pyrethroids, a common group of insecticides that are used to treat them. The mosquito Aedesaegyptiis known as a carrier of dengue, Zika virus and yellow fever.

    According to James Becnel, an entomologist of Mosquito and Fly Research Unit of USDA, Aedesaegypti was the reason for the limited Florida outbreaks of dengue in 2009 and 2010. When there are health emergencies, different strategies are used t control mosquitoes like the application of a pesticide sprays through trucks or aircraft. However, it is important to understand the magnitude of insecticide resistance before an effective control program can be undertaken.

    A first statewide study was made by a collaborative group from the USDA-ARS, Navy Entomology Center of Excellence, Florida Department of Agriculture and Consumer Services and Florida mosquito control districts. They measured the scope of pyrethroid insect resistance of Ae. Aegyptiand Aedesalbopictus. These are other species of mosquitoes carrying the chikungunya virus. Resistance to pyrethroid insecticides in many locations all over the world can have a negative on mosquito control operations.

    The 4-year study that was published in PLOS Neglected Tropical Diseases revealed that resistance to permethrin, an insecticide in the pyrethroid family was present in the 20 strains of Aedesaegypti collected all over the state. In order to effectively control the resistant populations, 60 times above the susceptible levels of permethrin doses must be used.

    Mosquitoes are present outdoors and it is important to wear Mozzie band in Australia to enjoy a summer picnic or family camping. The wristband is natural, non-toxic and DEET-free. It is safe to use and effective up to 48 hours.
