“…farauti varies widely among the geographic areas where it has been measured. In Papua New Guinea, the HBI of females collected indoors was 0.65–1.00 [ 5 , 39 – 41 ], when pooled for both indoors and outdoors was 0.68–0.88 [ 42 , 43 ], and when collected outdoors was 0.07–0.85 [ 2 , 5 , 39 – 41 , 44 ]. In the Solomon Islands, the HBI of females collected outdoors on Guadalcanal was 0.43 [ 45 ].…”

BackgroundThe proportion of blood meals that mosquitoes take from a host species is a function of the interplay of extrinsic (abundance and location of potential hosts) and intrinsic (innate preference) factors. A mark-release-recapture experiment addressed whether host preference in a population of Anopheles farauti was uniform or if there were anthropophilic and zoophilic subpopulations. The corresponding fitness associated with selecting different hosts for blood meals was compared by measuring fecundity.MethodsThe attractiveness of humans for blood meals by An. farauti in the Solomon Islands was compared to pigs using tent traps. Host fidelity was assessed by mark-release-recapture experiments in which different colour dusts were linked to the host to which the mosquito was first attracted. Outdoor resting An. farauti were captured on barrier screens and the human blood index (HBI) as well as the feeding index were calculated. The fecundity of individual An. farauti after feeding on either humans or pigs was assessed from blood-fed mosquitoes held in individual oviposition chambers.ResultsAnopheles farauti were more attracted to humans than pigs at a ratio of 1.31:1.00. The mark-release-recapture experiment found evidence for An. farauti being a single population regarding host preference. The HBI of outdoor resting An. farauti was 0.93 and the feeding index was 1.29. Anopheles farauti that fed on a human host laid more eggs but had a longer oviposition time compared to An. farauti that had blood fed on a pig.ConclusionsOne of the strongest drivers for host species preference was the relative abundance of the different host species. Here, An. farauti have a slight preference for humans over pigs as blood meal sources. However, the limited availability of alternative hosts relative to humans in the Solomon Islands ensures a very high proportion of blood meals are obtained from humans, and thus, the transmission potential of malaria by An. farauti is high.Electronic supplementary materialThe online version of this article (doi:10.1186/s12936-016-1168-y) contains supplementary material, which is available to authorized users.

“…This procedure was adopted in preference to the collection of daytime indoor-resting mosquitoes using the pyrethrin space-spray technique. Although the latter technique is more convenient, it would provide a grossly underestimated manbiting rate for the species of Ihe punctulatus complex, which are known to be endophagous-exophilic, with the majority of house-entering females leaving before dawn (van Thiel, 1954;Black, 1955;Peters and Standfast, 1960;Spencer, 1977). Field observations in the present study also showed that, while females freely enter houses and rest on walls before and after feeding, the majority leave again before dawn.…”

Summary. Seasonal prevalence and malaria transmission patterns of Anopheles farauti.An. punctulatus and An. koliensis were studied in two coastal and two inland villages in the Madang district of northern Papua New Guinea. The monthly manbiting rates (average biting density of vector mosquitoes per man per night) were observed over a two-year period to establish typical seasonal prevalence patterns. Observations on the frequency of feeding and the human blood index were combined to derive the manbiting habit. A daily survival rate was determined from the dissection of mosquito ovaries by Polovodova's age-grading method. The extrinsic cycle in the mosquito was not observed, and the value for this parameter was extracted from the literature. All parameters were combined to estimate the monthly variations in vectorial capacity of each of the vector species, and the vectorial capacities of the individual species were added together to give a total monthly vectorial capacity of the punctulatus complex in each locality. The results showed that malaria transmission can be perennial,

“…A number of studies analysing the stomach contents of blood-fed resting anophelines have been made in New Guinea (Black, 1955;Spencer, 1964;Slooff, 1964), but the number of mosquitoes and biotypes examined has been limited. In the Madang area, although all the members of the complex of Anopheles punctulatus Donitz, the primary vectors of malaria in Papua New Guinea, will readily feed inside or outside houses, all complete their gonotrophic development outside.…”

Samples of engorged outdoor-resting females of the complex ofAnopheles punctulatusDönitz, primarilyA. farautiLaveran, were obtained from villages in Madang Province, Papua New Guinea, in 1981–83 and their blood-meal sources identified. The proportion of the population feeding on man varied considerably from village to village according to the number of animals, particularly pigs, available as alternative hosts. Using a unique host in a mark–release–recapture experiment, the distance flown by engorged females ofA. farautiwas found to be generally less than 50 m. In one village, the gonotrophic age of a subsample of 1523 females ofA. farautiwas obtained and in 503 of these the electrophoretic pattern of the enzyme phosphoglucomutase (PGM) determined. Tests of association were per formed on the data. However, no significant relationship was found between host source, gonotrophic age and allelic type of PGM. Thus, separate subpopulations ofA. farautiwere not identified within this village. The relevance of the results to the epidemiology of malaria is discussed.
