The bionomics of the malaria vector Anopheles farauti in Northern Guadalcanal, Solomon Islands: issues for successful vector control

Table 1 The entomological estimation of the feeding behaviour and survival rates of Anopheles farauti from three villages on Northern Guadalcanal, Solomon Islands during July 2007 to June 2008

Entomological parameters	Gilutae	Komporo	Red Beach	Overall
Biting rate (B: b/p/n)
Indoor	7.00	6.62	15.8	9.66
Outdoor	17.18	14.98	19.09	17.08
Overall	12.09	10.80	17.07	13.40
Endophagy¹ (Proportion indoors ± se)	0.29 ± 0.014 (n = 1,064)	0.31 ± 0.015 (n = 907)	0.44 ± 0.013 (n = 1,434)	0.36 ± 0.008 (n = 3,405)
Nocturnal biting² (Proportion 21.00-05.00 ± se)	0.31 ± 0.014 (n = 1,064)	0.35 ± 0.016 (n = 907)	0.39 ± 0.013 (n = 1,434)	0.35 ± 0.008 (n = 3,405)
Parity (Proportion parous) (n/total)	0.542 (552/1,017)	0.577 (523/906)	0.541 (764/1,412)	0.551 (1,839/3,335)

B = no. of mosquitoes collected/no. of nights/no. of collectors.
¹Proportion of mosquitoes caught indoors calculated as: I_{18.00 → 06.00}/(I_{18.00 → 06.00} + O_{18.00 → 06.00}); where I = the total number of mosquitoes caught indoors, O = the total number of mosquitoes caught outdoors and the subscripts represent the time for each hour.
²Proportion of mosquitoes caught during hours when most people are asleep calculated as: (I_{22.00 → 05.00} + O_{22.00 → 05.00})/(I_{18.00 → 06.00} + O_{18.00 → 06.00}).
