Technical Abstract: This study is part of an over-arching effort to understand Asian citrus psyllid (ACP) host-finding behavior and develop scent attractants to improve ACP detection and monitoring. Because it is oligophagous, ACP response to host-plant stimuli should be primarily innate. However, the capability to respond conditionally could enable ACP to track the physiological status of local host-plants. This is key since it only reproduces on very young foliage. To gauge ACP behavioral plasticity to semiochemicals it would encounter during host-plant selection, we measured its innate and conditional responses to: 1. Limonene, a common foliar monoterpene 2. Ethyl butanoate, a common fruit ester 3. Vanillin, an ecologically neutral compound A follow-up test examined the effect of mixing a conditional compound (vanillin) with an unconditionable compound (ethyl butanoate) following conditioning on vanillin.
