Gut bacteria facilitate adaptation to crop rotation in the western corn rootworm

Mostrar otras versiones (1)

Insects are constantly adapting to human-driven landscape changes; however, the roles of their gut microbiota in these processes remain largely unknown. The western corn rootworm [WCR, Diabrotica virgifera virgifera LeConte] [Coleoptera: Chrysomelidae] is amajor corn pest that has been controlled vi...

520 |a Insects are constantly adapting to human-driven landscape changes; however, the roles of their gut microbiota in these processes remain largely unknown. The western corn rootworm [WCR, Diabrotica virgifera virgifera LeConte] [Coleoptera: Chrysomelidae] is amajor corn pest that has been controlled via annual rotation between corn [Zea mays] and nonhost soybean [Glycine max] in the United States. This practice selected for a 'rotation-resistant' variant [RR-WCR] with reduced ovipositional fidelity to cornfields.When in soybean fields, RRWCRs also exhibit an elevated tolerance of antiherbivory defenses [i.e., cysteine protease inhibitors] expressed in soybean foliage. Here we show that gut bacterial microbiota is an important factor facilitating this corn specialist's [WCR's] physiological adaptation to brief soybean herbivory. Comparisons of gut microbiota between RR- and wild-type WCR [WT-WCR] revealed concomitant shifts in bacterial community structure with host adaptation to soybean diets. Antibiotic suppression of gut bacteria significantly reduced RR-WCR tolerance of soybean herbivory to the level of WT-WCR, whereas WTWCR were unaffected. Our findings demonstrate that gut bacteria help to facilitate rapid adaptation of insects inmanaged ecosystems.
