For example, larvicides can be used in mosquito breeding zones; insecticides can be applied to house walls or bed nets, and use of personal repellents can reduce incidence of insect bites and thus infection. The use of pesticides for vector control is promoted by the World Health Organization (WHO) and has proven to be highly effective. [7]
A bug zapper, more formally called an electrical discharge insect control system, electric insect killer or (insect) electrocutor trap, is a device that attracts and kills flying insects that are attracted by light. A light source attracts insects to an electrical grid, where they are electrocuted by touching two wires with a high voltage ...
Photuris female by flash photography (above); by her own light (below) Light production in fireflies is due to the chemical process of bioluminescence. This occurs in specialized light-emitting organs, usually on a female firefly's lower abdomen. The enzyme luciferase acts on luciferin, in the presence of magnesium ions, ATP, and oxygen to ...
Vector control in some regions has been hindered by the development of insecticide resistance among triatomine bugs. [34] In response, vector control programs have implemented alternative insecticides (e.g. fenitrothion and bendiocarb in Argentina and Bolivia), treatment of domesticated animals (which are also fed on by triatomine bugs) with ...
This field of light is monitored by charge-coupled devices (CCDs) similar to the ones used in consumer digital cameras. [6] These cameras are situated on both fence posts and detect shadows in the light between the posts. Once an insect is detected, a non-lethal laser is fired at it.
A triatomine bug serves as the vector. While taking a blood meal, it ingests T. cruzi. In the triatomine bug (the principal species of which in terms of parasite transmission to humans being Triatoma infestans) the parasite goes into the epimastigote stage, making it possible to reproduce. After reproducing through binary fission, the ...
Simulium, the type genus, is the most widespread and is a vector for several diseases, including river blindness. Mature adults can disperse tens or hundreds of miles from their breeding grounds in fresh flowing water, under their own power and assisted by prevailing winds, complicating control efforts.
Diaphorina citri, the Asian citrus psyllid, is a sap-sucking, hemipteran bug now in the taxonomic family Liviidae. [1] It is one of two confirmed vectors of citrus greening disease . [ 2 ] [ 3 ] It has a wide distribution in southern Asia and has spread to other citrus growing regions.
