Table 4 The entomological estimation of malaria transmission intensity attributable to Anopheles farauti on Popoheo village and Anopheles solomonis on Kolosori village, Santa Isabel province, Solomon Islands during October of 2009.

From: Changes in vector species composition and current vector biology and behaviour will favour malaria elimination in Santa Isabel Province, Solomon Islands

Entomological parameters of mosquito population Popoheo Anopheles farauti Kolosori Anopheles solomonis
Sporozoite prevalence (S; %) 0.00129 (n = 775) 0.0000 (n = 287)
Biting rate (B; b/p/n)

  1. Where S = no. of sporozoite positive mosquitoes/no. of mosquitoes tested, B = no. of mosquitoes collected/no. of nights/no. of collectors, EIR = S × Boverall × 365. Endophagy was the proportion of mosquitoes caught indoors (calculated as I6 pm5 am/(I6 pm5 am + O6 pm5 am, where I and O = the total number of mosquitoes caught indoors and outdoor respectively between 6 pm and 5 am); nocturnal biting was the proportion of mosquitoes caught during hours (10 pm-5 am) when most people are asleep (calculated as I9 pm4 am + O9 pm4 am)/(I6 pm5 am + O6 pm5 am where I and O = the total number of mosquitoes caught indoors and outdoor respectively at the time indicated); and πi the proportion of the vector population biting indoors adjusted for the location of the host either outdoors or indoors [12]
