Insect-Associated Bacteria Boost VOC Emissions, Including Benzenoids, Esters, Hydrocarbons, and Lactone, during Cereal Leaf Beetle Feeding on Wheat.

ABSTRACT: Plant volatile organic compounds (VOCs) constitute part of the signal transmitted between plants, serving as defence molecules that repel plant pests or attract their natural enemies. Insect-associated bacteria are important factors influencing many aspects of plant-insect interactions. In this study, we have undertaken to evaluate the impact of the insect-associated bacteria on the abundance and the content of VOCs emitted from wheat plants damaged by important cereal pest - cereal leaf beetle (CLB, Oulema melanopus), in both larval and adult stages. We assumed that CLB-associated bacteria, as an additional factor, may cause different and higher VOC emissions from plants attacked by insects. VOCs were collected by solid-phase microextraction and analyzed with comprehensive two-dimensional
