红掌象甲是一种入侵害虫，在世界上许多地区的棕榈树栽培中造成严重的经济损失。迫切需要开发有效的方法来控制这种害虫。此前的研究集中在其嗅觉的分子基础上，导致对该物种聚集信息素受体的鉴定，这有助于开发生物传感器和诱饵陷阱。为了更好地了解该物种的化学感受，我们使用生物信息学方法从其基因组和转录组数据中识别所有味觉受体基因。有50个味觉受体基因编码65个功能性受体，包括二氧化碳、糖和苦味受体。我们的结果将有助于阐明这种甲虫如何辨别和评估食物和产卵地点，并通过味觉进行交流。红棕榈象是亚洲、欧洲和非洲许多地区油棕榈树、枣树和椰子的一种极具破坏性的害虫。联合国粮食及农业组织呼吁国际合作，制定一项多学科战略来控制这种入侵害虫。以前的研究集中在该物种化学感受的分子基础上，特别是嗅觉，以开发用于早期检测的生物传感器和用于大规模诱捕的更有效的诱饵陷阱。然而，味觉在区分该物种的食物和产卵位置以及化学交流中起着至关重要的作用，但由于其完整的味觉受体基因家族尚不清楚，因此其分子基础是有限的。我们从最近可用的基因组和转录组数据中手动注释了该基因家族，并报告了50个味觉受体基因，编码65个味觉受体，包括7个二氧化碳、9个糖和49个苦味受体。本研究为今后的功能分析和比较化学感觉研究提供了平台。更好地了解味觉将提高我们对该物种复杂的化学感受的理解，这是朝着开发更有效的控制方法迈出的重要一步。
The red palm weevil (Rhynchophorus ferrugineus) is an invasive pest that causes severe economic loss in palm plant cultivation (e.g., oil palm, date, and coconut) in many regions of the world. The development of efficient approaches to controlling this pest is urgently needed. Previous research focused on the molecular basis of its olfaction, leading to the identification of this species’ aggregation pheromone receptor, which can help develop biosensors and bait traps. To gain more understanding of the chemoreception in this species, we used a bioinformatic approach to identify all the gustatory receptor genes from its genome and transcriptome data. There are 50 gustatory receptor genes encoding 65 functional receptors, including CO2, sugar, and bitter receptors. Our results will help elucidate how this beetle discriminates and evaluates food and egg-laying sites and communicates via gustation. The red palm weevil (Rhynchophorus ferrugineus) is a highly destructive pest of oil palm, date, and coconut in many parts of Asia, Europe, and Africa. The Food and Agriculture Organization of the United Nations has called for international collaboration to develop a multidisciplinary strategy to control this invasive pest. Previous research focused on the molecular basis of chemoreception in this species, particularly olfaction, to develop biosensors for early detection and more effective bait traps for mass trapping. However, the molecular basis of gustation, which plays an essential role in discriminating food and egg-laying sites and chemical communication in this species, is limited because its complete gustatory receptor gene family still has not been characterized. We manually annotated the gene family from the recently available genome and transcriptome data and reported 50 gustatory receptor genes encoding 65 gustatory receptors, including 7 carbon dioxide, 9 sugar, and 49 bitter receptors. This study provides a platform for future functional analysis and comparative chemosensory study. A better understanding of gustation will improve our understanding of this species’ complex chemoreception, which is an important step toward developing more effective control methods.
