2-butanone as a carbon dioxide mimic in attractant blends for the Afrotroical malaria mosquitoes anopheles gambie and anopheles funestus
Mburu, Monicah M.; Mweresa, Collins K.; Omusula, Philemon; Hiscox, Alexandra; Takken, Willem; Mukabana, Wolfgang R. (Malaria Journal, 2017-08-24)Most odour baits designed to attract host-seeking mosquitoes contain carbon dioxide (CO2), which enhances trap catches, given its role as a mosquito fight activator. However, the use of CO2 is expensive and logistically ... -

Mweresa, Collins K.; Mukabana, Wolfgang R.; Omusula, Philemon; Otieno, Bruno; Van Loon, Joop J. A.; Takken, Willem (SpringerLink, 2016-06-27)The deployment of odor-baited tools for sampling and controlling malaria vectors is limited by a lack of potent synthetic mosquito attractants. A synthetic mixture of chemical compounds referred to as “the Mbita blend” ... -
