<p><strong>Chemosensory systems in predatory mites: from ecology to genome</strong></p>

The reception of chemical cues in the environment is essential for survival almost all organisms, including phytoseiid mites. Compared with progress made field insect olfaction, understanding how predatory mites perceive compounds and react to their surroundings merely fragmentarily documented past decades. In this review, we provide a guide from chemoecology herbivore-induced plant volatiles (HIPVs) as early 1980s advances comparative genomics 2019. We present three aspects, i.e., chemosensory-guided feeding behavior, sensory structures chemoreceptors predicted genomes. molecular principles chemosensory system remain exciting areas future research, since insights into mechanisms underlying sensing signals will not only contribute better predator behavior physiology but may also open new avenues development more specific sustainable approaches control pests by manipulating behaviors predators. then suggest directions research: 1) chemoreceptor gene identification function verification; 2) neural response circuit stimuli 3) application chemoperception on behavior. potential methods techniques are provided well.
