“…The strong human-biting preferences and highly domestic habits of the tropical African vectors (17,39) lead to very uniform contact between them and the human blood source in sub-Saharan Africa. The climatic conditions are also highly conducive to malaria transmission, being warm and humid with relatively few fluctuations.…”

“…Outside of Africa, wherever malaria is or has been endemic, the female mosquito vectors of malaria are zoophilic rather than anthropophilic; i.e., they prefer to feed on animals rather than on humans (17). The degree of preference for human blood has important consequences for human malaria transmission (124).…”

“…In most parts of the world, the anthropophilic index (the probability of a blood meal being on a human) of the vectors of malaria is much less than 50% and often less than 10 to 20% (17). By contrast, in sub-Saharan Africa, the vectors of human malaria usually have an anthropophilic index of 80 to almost 100% (17).…”

Malaria is among the oldest of diseases. In one form or another, it has infected and affected our ancestors since long before the origin of the human line. During our recent evolution, its influence has probably been greater than that of any other infectious agent. Here we attempt to trace the forms and impacts of malaria from a distant past through historical times to the present. In the last sections, we review the current burdens of malaria across the world and discuss present-day approaches to its management. Only by following, or attempting to follow, malaria throughout its evolution and history can we understand its character and so be better prepared for our future management of this ancient ill

“…Reduced anthropophagy of Anopheles mosquitoes in rice scheme areas has been reported by several studies, and has often been associated with a decrease in malaria transmission. [43][44][45] This suggests that keeping cattle near human dwellings coupled with effective mass coverage of bed nets can divert even strongly anthropophagic species like An. gambiae in areas where densities of this vector are exceptionally high.…”

Abstract. Barriers to gene flow between Pacific and Atlantic coast populations of Anopheles albimanus were reported in an earlier study of variation in the intergenic spacer of the nuclear ribosomal DNA. We examined the distribution of mitochondrial DNA haplotypes among A. albimanus populations to test for gene flow barriers with an independent genetic marker. A region of the NADH dehydrogenase subunit 5 gene was amplified by the polymerase chain reaction (PCR) in 1,105 mosquitoes collected from 16 locations in Guatemala and in single collections from Mexico, Honduras, Nicaragua, Costa Rica, Panama, Colombia, and Venezuela. The PCR products were tested for variation using single strand conformation polymorphism analysis and 45 haplotypes were detected. Haplotype frequencies did not vary between coasts in Guatemala. Populations within ϳ200 km of one another were panmictic. However, at distances Ͼ 200 km, F ST and geographic distances were correlated suggesting that populations are isolated by distance.Anopheles albimanus is one of the major vectors of malaria in Central America, the Caribbean, and coastal regions of northern South America. It feeds more readily on animals than humans, 1-3 and is generally exophilic in host-seeking and feeding behavior. [4][5][6] Sporozoite rates are generally low, with the greatest reported rate at only 1.6% (1 of 63). 7 However, these behavioral characteristics and vector competence estimates vary greatly among A. albimanus populations. 8 We have been testing for the presence of cryptic species within A. albimanus because of the strong historical precedence for the existence of cryptic, isomorphic Anopheles species.In an earlier study of Guatemalan A. albimanus populations, we observed a high degree of variation both in the frequency and copy number of intergenic spacer (IGS) length variants among individual A. albimanus. 9 Regardless of the collection site, most of the variation either in frequency or intensity of IGS variants was detected among mosquitoes within a population. The next largest component of genetic differentiation was detected between populations on the Pacific and Atlantic coasts of Central America. In contrast, populations from the Atlantic coast of Central America and from South America had similar IGS patterns. We suggested that the many mountain ranges that run through northern Central America could form barriers to gene flow among Atlantic and Pacific coast populations. However, extreme local variation in rDNA IGS has been found in many population studies of other insect species and is consistent with a model whereby molecular drive rapidly gives rise to unique spacer patterns in populations and then drives them to high frequencies. [10][11][12][13] In the case of A. albimanus, molecular drive probably occurs through unequal crossing-over and gene conversion within and among the 100-basepair (bp) repeat units constituting the IGS. 14 In the present paper, we test the inferences arising from our earlier rDNA study using an independent marker: variation in t...
