Olfactory responses of Cx. pipiens females to odour extracts of selected bird species

Bird species	N (%) odour	N (%) control	χ 2	d.f.	p( χ 2 )	Ryan’s test
Blackbird	39 (90.7)	4 (9.3)	28.88	1	<0.001	a
Eurasian blackcap	49 (66.2)	25 (33.8)	7.15	1	<0.01	b
Eurasian magpie	34 (65.4)	18 (34.6)	4.33	1	<0.05	b
House sparrow	54 (64.8)	35 (35.2)	4.16	1	<0.05	b

Columns description. N (%) odour: number and percentage of mosquitoes that exhibited preference to the odour extract solution; N(%) control: number and percentage of mosquitoes that exhibited preference to the solvent; χ2 statistics: chi-square test comparing the proportion of mosquitoes choosing odour vs. control for each bird species; Ryan’s test: comparison of proportions of mosquitoes choosing the odour coming from different bird species (rows with the same letter indicate that proportions are not statistically different at 0.05 level).
