Bacteria were always recovered from degraded tissue of large and mid‐sized tarnished plant bug ( Lygus lineolaris ) lesions, less frequently from small lesions and bumps, and rarely from healthy tissues of current year shoots of hybrid poplar in southern Ontario, Canada. All 209 isolates obtained were gram‐negative rods; 61 were members of the Enterobacteriaceae. Compartmentalized disrupted areas in the xylem were associated with bumps and large insect incited lesions. Large numbers of bacteria were associated with pockets of thick‐walled fibers in the disrupted tissues. Microscopic observations suggest that bacteria contribute to degradation of disrupted tissues through breakdown of the fibers. The role of bacteria in TPB lesion formation, however, is still not clear.
