- The piercing-sucking herbivores Lygus hesperus and Nezara viridula induce volatile emissions in plantsLivy Williams
United States Department of Agriculture, Agricultural Research Service, Southern Insect Management Research Unit, Stoneville, Mississippi 38776 0346, USA
Arch Insect Biochem Physiol 58:84-96. 2005..Although oviposition and mechanical injury by stylets may increase release of volatiles, elicitors from salivary glands of L. hesperus and N. viridula also seem to play a role in the emission of plant volatiles...
