using maldi-tof ms to identify mosquitoes collected in mali and their blood meals.matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (maldi-tof ms) has been recently described as an innovative and effective tool for identifying arthropods and mosquito blood meal sources. to test this approach in the context of an entomological survey in the field, mosquitoes were collected from five ecologically distinct areas of mali. we successfully analysed the blood meals from 651 mosquito abdomens crushed on whatman filter paper (wfps) in the field using maldi-t ...201829409547
mosquito host preferences affect their response to synthetic and natural odour blends.the anthropophilic malaria mosquito anopheles gambiae sensu stricto (hereafter termed anopheles gambiae) primarily takes blood meals from humans, whereas its close sibling anopheles arabiensis is more opportunistic. previous studies have identified several compounds that play a critical role in the odour-mediated behaviour of an. gambiae. this study determined the effect of natural and synthetic odour blends on mosquitoes with different host preferences to better understand the host-seeking beha ...201525889954
the fitness of african malaria vectors in the presence and limitation of host behaviour.host responses are important sources of selection upon the host species range of ectoparasites and phytophagous insects. however little is known about the role of host responses in defining the host species range of malaria vectors. this study aimed to estimate the relative importance of host behaviour to the feeding success and fitness of african malaria vectors, and assess its ability to predict their known host species preferences in nature.201223253167
chicken volatiles repel host-seeking malaria mosquitoes.anopheles arabiensis is a dominant vector of malaria in sub-saharan africa, which feeds indoors and outdoors on human and other vertebrate hosts, making it a difficult species to control with existing control methods. novel methods that reduce human-vector interactions are, therefore, required to improve the impact of vector control programmes. investigating the mechanisms underlying the host discrimination process in an. arabiensis could provide valuable knowledge leading to the development of ...201627439360
interventions that effectively target anopheles funestus mosquitoes could significantly improve control of persistent malaria transmission in south-eastern tanzania.malaria is transmitted by many anopheles species whose proportionate contributions vary across settings. we re-assessed the roles of anopheles arabiensis and anopheles funestus, and examined potential benefits of species-specific interventions in an area in south-eastern tanzania, where malaria transmission persists, four years after mass distribution of long-lasting insecticide-treated nets (llins). monthly mosquito sampling was done in randomly selected households in three villages using cdc l ...201728542335
variation in host preferences of malaria mosquitoes is mediated by skin bacterial volatiles.the host preferences of the anthropophilic mosquito species in the anopheles gambiae complex (diptera: culicidae) are mediated by skin bacterial volatiles. however, it is not known whether these mosquitoes respond differentially to skin bacterial volatiles from non-human host species. in this study, the responses of two malaria mosquito species in the an. gambiae complex, anopheles gambiae s.s. (hereafter, an. gambiae) and anopheles arabiensis, with different host preferences, to volatiles relea ...201728639690
using mid-infrared spectroscopy and supervised machine-learning to identify vertebrate blood meals in the malaria vector, anopheles arabiensis.the propensity of different anopheles mosquitoes to bite humans instead of other vertebrates influences their capacity to transmit pathogens to humans. unfortunately, determining proportions of mosquitoes that have fed on humans, i.e. human blood index (hbi), currently requires expensive and time-consuming laboratory procedures involving enzyme-linked immunosorbent assays (elisa) or polymerase chain reactions (pcr). here, mid-infrared (mir) spectroscopy and supervised machine learning are used t ...201931146762
