Four different traps, Biogents Sentinel trap (BG trap), Heavy Duty Encephalitis Vector Survey trap (EVS trap), Centres for Disease Control miniature light trap (CDC trap) and Mosquito Magnet Patriot Mosquito trap (MM trap) were compared in a 4×4 latin square study. In the years 2012 and 2013, more than seventy 24-hour trap comparisons were conducted at ten different locations in northern and southern Germany, representing urban, forest and floodplain biotopes.Read more »

Press release: 1400 households, 450 Biogents traps, uncounted dengue mosquitoes – a long-term study in Brazil

Regensburg 2014/03/27 – Dengue fever is widely distributed in Brazil and other tropical and subtropical regions and a constant threat to the local population. Dengue is mosquito-borne virus that infects up to 100 million people each year. Because there is no effective vaccine available, the only way to control the disease is by controlling the dengue mosquitoes. While the use of conventional insecticides is widespread, they have become increasingly ineffective due to insecticide resistance.
A new approach to control the mosquitoes could be the mosquito trap developed by Biogents. A large-scale study published in the Entomological Society of America’s Journal of Medical Entomology has demonstrated for the first time that these traps can also reduce the number of dengue mosquitoes (Aedes aegypti) in a broad urban area. The study co-financed by the world-bank was conducted over 18 months with more than 1400 households and 450 Biogents traps in Manaus, Brazil.
The result: „The study shows that the Biogents traps can significantly reduce the amount of adult female Aedes aegypti especially in the rainy season” says Prof. Eiras from the University Federal de Minas Gerais (Brazil). The number of dengue infections in the test areas also decreased. An additional advantage for household trap users was the Biogents traps also reduced numbers of the annoying and often numerous tropical house mosquito (Culex quinquefasciatus). Households that used the traps reported a noticeable reduction in the nuisance from mosquitoes. Additional studies will be required to investigate the effects of trapping on larger scales and during epidemics.
