Plasticity of host selection by malaria vectors of Papua New Guinea

Parasites & Vectors

Table 2 Results for homogeneity of proportion (3 × 2 contingency table) test comparing the relative number of the three primary hosts in the village with their number in the mosquito blood meals. Mosquito feeding is considered disproportional to the host availability when the χ ² test appeared statistically significant and proportional when insignificant

Village	Anopheles species	Host species	No. of hosts in the village	No. of hosts in the blood meals	χ ² test statistic	P-value	Feeding outcome
Matukar	An. farauti (s.s.)	humans	432	33	χ ² = 2.62	0.25	proportional
		pigs	67	2
		dogs	76	8
Mirap	An. farauti (s.s.)	humans	732	541	χ ² = 281.9	0.0005	disproportional
		pigs	110	522
		dogs	112	94
Wasab	An. punctulatus (s.s.)	humans	211	76	χ ² = 7.2	0.02	disproportional
		pigs	71	10
		dogs	48	17
Wasab	An. longirostris	humans	211	57	χ ² = 8.7	0.015	disproportional
		pigs	71	14
		dogs	48	2
Dimer	An. punctulatus (s.s.)	humans	622	20	χ ² = 11.26	0.009	disproportional
		pigs	158	2
		dogs	94	9
Kokofine	An. farauti no. 4	humans	167	221	χ ² = 70.7	0.0005	disproportional
		pigs	70	189
		dogs	88	33

Note: degrees of freedom is irrelevant to report along with the Pearson’s χ ² result because the P-value was computed by Monte Carlo simulation
