Contrasting

Order By: Relevance

“…These apparently large contrasts in host choice by An. gambiae in East and West Africa may result from between-site differences in innate behavioural traits of the vectors (Touré et al, 1994;Lanzaro et al, 1998;COETZEE et al, 2000), spatial relationships of hosts, vectors and larval habitats (Kitron & Spielman, 1989;Kitron, 1998), personal protection (Lindsay et al, 1989 or housing design (Gamage-Mendis et al, 1991;Ghebreyesus et al, 2000). Of these factors, the unusually longstanding and widespread use of bednets in The Gambia deserves particular attention because such domestic personal protection measures can discourage feeding on humans and reduce human blood indices (Garrett-Jones, 1964;Charlwood & Graves, 1987;Lindsay et al, 1989;Githeko et al, 1996a;Bøgh et al, 1998).…”

A simple model for the influence of host availability on vector bloodmeal choice is applied to estimate the relative availabilities of humans, cattle and other host populations to malaria vectors in African communities, using published human blood indices and ratios of cattle to humans. Cattle were bitten <0.01, 0.021 ± 0.11, 1.61 ± 0.16 and 1.61 ± 0.46 times as often as humans by Anopheles funestus, An. gambiae sensu stricto and An. arabiensis in Segera, Tanzania, and An. gambiae sensu lato in The Gambia, respectively. No significant feeding upon host species other than cattle or humans was detected. Even though An. gambiae s.l. in The Gambia were mostly An. gambiae s.s., they were 77 times more likely to choose cattle over humans than An. gambiae s.s. in Tanzania. The model accurately predicted cattle blood indices for the An. arabiensis population in Tanzania (predicted = 0.99 ± 0.21 × observed + 0.00 ± 0.10; r 2 = 0.66). The potential effect of increased cattle abundance upon malaria transmission intensity was simulated using fitted relative availability parameters and assuming vector emergence rate, feeding cycle length and survivorship were unaffected. The model predicted that increased cattle populations would not affect malaria transmission in Tanzania but could drastically reduce transmission in The Gambia or where An. arabiensis is the dominant vector. We define the availability of a host as the rate at which a typical individual host-seeking vector encounters and feeds upon that host in a single feeding cycle. Mathematical models based on this definition also represent promising tools for quantifying the dependence of vector longevity, feeding cycle length and dispersal upon host availability.

“…The global distribution of per-capita gross domestic product (GDP) shows a distinct correlation between malaria and poverty. The reverse is true for countries where malaria has been eradicated (Gallup and Sachs 2001 (Coetzee et al 2000, White 1974) and An. quadriannulatus species B (Hunt et al 1998).…”

“…Anopheles gambiae, the nominal taxon, and An. arabiensis are the most important vector species in the complex (Coetzee et al 2000, Gillies and De Meillon 1968, Gillies and Coetzee 1987, White 1974. The occurrence of 80% of the world's malaria in tropical Africa (WHO 1993) is due to the strong human biting habits (anthropophily) and relatively long lifespan of these two species (Collins and Besansky1994), besides An.…”

“…While the cytogenetic approach has proven to be powerful for mosquito taxonomy [i.e. A. maculipennis and A. gambiae complexes (Frizzi 1947, 1953, Coluzzi 1966, Coetzee et al 2000], its application is time consuming and requires specialized skills.…”
