Effects of bacterial endophytes on plant-insect interactions
Abstract
Insects must interact with bacterial endophytes when sharing a common host. To test the hypothesis that larvae of Scaptomyza nigrita detects and prefers Cardamine cordifolia infected with different strains of Pseudomonas bacteria. Thus, unitizing the JA/SA induced antagonism. When given the choice between an infected leaf and a non-‐infected leaf, larvae demonstrated a significant preference towards leaves infected with Pseudomonas bacteria. Plants in which leaves were treated with Pseudomonas strains showed a significant reduction in chlorophyll content. Suggesting that larval preference correlates with the effect the bacterium has on its host plant.
