The Mosquito - Also known as the 'Teenage Repel'ent Device". Al Aynsley-Green, Children's Commissioner for England, said he had spoken to many young people ... Si tratta di lampadine ricoperte di un pigmento giallo luminoso sulla parte interna del bulbo di vetro che viene utilizzato per schermare la radiazione UV. Quando sono accese emetteranno una luce con una lunghezza d'onda particolare (tra i 570-580 nm) che emette una luce di colore giallo che dovrebbe allontanare le zanzare. La domanda sorge spontanea: Funziona? Ebbene si, esiste anche documentazione scientifica a riguardo. Photon (light) technology has already been widely used in make-up, medical treatment etc, but repelling mosquitoes by photon technology is an innovation. The objective of this study was to determine the efficacy of a mosquito repelling lamp, E Da under indoor conditions. E Da lamp is a lamp coated with yellow luminous pigment on the inner part of the glass bulb of the lamp which is used to screen out the UV radiation, and when it is turned on, the yellow illuminating wavelength will drive the mosquitoes away. The tests were conducted inside 2 cabins measuring 8′ × 8′ × 20′. The mosquito population was estimated by using the Bare Leg Catch (BLC) techniques. For treated test, E Da lamp was placed indoor 2-3 meters away from a human bait. Another cabin without the lamp was used as untreated control. BLC was conducted in both sites simultaneously. The mosquitoes collected in this study were solely those of Culex quinquefasciatus and Aedes albopictus. There was an 91.34% reduction of Cx. quinquefasciatus population in the treated test compared with the untreated cabin during the 4 hours catches . E Da mosquito repelling lamp used in this study exerted repellency effect against the mosquitoes especially Cx. quinquefasciatus. Durante i test svolti presso la Malaysian Society of Parasitology and Tropical Medicine sono state utilizzate due specie di zanzara: la Culex quinquefasciatus e la Aedes albopictus meglio conosciuta come zanzare tigre. L'effetto repellente della lampada verso le prime è stato un successo, la popolazione di zanzare è stata ridotta del 91,34%. They do work provided that you are surrounded by other non-yellow lights. If you have no neighbors and the only light that will be out there are yellow lights, mosquitoes will go.
