Abstract:		"Herbivory byThrips tabaci affected production of the phytohormone ethylene from living onion foliage. Ethylene analysis was performed by gas chromatography on intact onion tissue. Thrips feeding damage and a crushed thrips extract stimulated significantly greater production of eihylene than could be explained by either one-time or semicontinuous mechanical damage alone, suggesting that ethylene-inducing cues may be transferred to the plant during feeding. This is the first demonstration of increased ethylene production from insect-infested intact plants. This study suggests that herbivores affect both the phytohormone physiology and secondary chemistry of living plants because ethylene has been shown to enhance production of defensive phytochemicals"
