  "summary": "Chemoreception plays an important role in how insects sense their environment and interact with other organisms. One important ecological role for chemosensory receptors is sensing chemical compounds to locate suitable host plants. Host-plant use is therefore expected to influence insect sensory system evolution as host-plant preferences changes and species become more generalized or specialized.…",
