Salicinoid phenolics reduce adult Anoplophora glabripennis (Cerambicidae: Lamiinae) feeding and egg production

Plant chemistry plays an important role in mediating resistance against insect herbivores. Depending on species and feeding strategies, plant defenses can prevent attacks, impact digestive physiology influence reproductive output. The Asian longhorned beetle (Anoplophora glabripennis) is invasive, tree-killing that exploits multiple host species. Anoplophora glabripennis documented to attack Populus spp., but the ability for adults consume varies between populations. In this study, we explored of salicinoid phenolic glycosides, known be potent chemical generalist insects, A. adult behavior fecundity. We performed a series choice- no-choice experiments using extracts salicinoids applied plants do not produce these compounds. Salicinoids affected performance dose-dependent manner, with higher concentrations significantly reducing feeding. Egg development was reduced by > 90% females fed at ~ 1.3% dry weight. then compared present material vs. frass found both decrease concentration shift composition However, some more complex were unchanged excrement, suggesting minimal detoxification had occurred. Our results show disrupt egg glabripennis, thereby fitness. These have implications how metabolizes defense chemicals tolerance may vary among
