Table 4. Results of the spatial co-location test excluding the intrinsic correlation.

Between points…	For α = 0,01 and m = 1
	Mean of minimum distances (m)		p-value
	Observed	Simulated
L-IgG-POS and TOSV-IgG-POS	509	[411–588]	>0.05
TOSV-IgG-POS and L-IgG-POS	619	[506–670]	>0.05

It was performed in order to test the global relationship between L-IgG-POS and TOSV-IgG-POS individuals. When the intrinsic correlation was excluded from spatial correlation (i.e. the nearest positive neighbour of a positive point needed to be another object), the tests used showed no significant spatial co-location.
