Insect immunity: oral exposure to a bacterial pathogen elicits free radical response and protects from a recurring infection

Table 1 Pairwise differences in larval mortality between the priming-injection treatments

Priming-injection	Serratia-control		control-Serratia		control-control
	χ ²	Sig.	χ ²	Sig.	χ ²	Sig.
Serratia-Serratia	12.641	<0.001	64.92	<0.001	19.72	<0.001
Serratia-control			115.38	<0.001	1.07	0.300
control-Serratia					130.57	<0.001

The larvae were primed orally with either a non-infective dose of pathogenic Serratia marcescens or a non-pathogenic control bacterium Escherichia coli, and five days later injected with the same or different bacteria.
Statistically significant pairwise differences are bolded.
