It is increasingly clear that microbial plant symbionts can influence
interactions between their plant hosts and other organisms. Yet, such
effects remain poorly understood, particularly under ecologically
realistic conditions where plants simultaneously interact with diverse
mutualists and antagonists. Here we examine how the effects of a plant
virus on indirect plant defenses against its insect vector are influenced
by co-occurrence of other microbial plant symbionts. Using a
multi-factorial design, we manipulated colonization of soybean using three
different microbes: a pathogenic plant virus (Bean pod mottle virus
[BPMV]), a nodule-forming beneficial rhizobacterium (Bradyrhizobium
japonicum), and a plant growth-promoting rhizobacterium (PGPR) (Delftia
acidovorans). We then assessed recruitment of parasitoids (Pediobious
foveolatus [Eulophidae]) and parasitism rates following feeding by the
BPMV vector Epilachna varivestis (Coccinellidae). BPMV infection
suppressed parasitoid recruitment, prolonged parasitoid foraging time, and
reduced parasitism rates in semi-natural foraging assays. However,
simultaneous colonization of BPMV-infected hosts by both rhizobacteria
restored parasitoid recruitment and rates of parasitism to levels similar
to uninfected controls. Co-colonization by the two rhizobacteria also
enhanced parasitoid recruitment in the absence of BPMV infection. These
results illustrate the potential of plant-associated microbes to influence
indirect plant defenses, with implications for disease transmission and
herbivory, but also highlight the potential complexity of such
interactions.
