The Colorado potato beetle (CPB), Leptinotarsa decemlineata, is a major potato (Solanum tuberosum) pest, infesting over 16 million km² and causing substantial economic losses. The insect cuticle forms an apical extracellular matrix (ECM) envelope covering exposed organs to direct morphogenesis and confer structural protection. While select chitinase (Cht) genes have proven essential for larval development, their potential activities directing ECM remodeling underlying adult wing maturation remain undefined.

特殊几丁质酶在 Leptinotarsa decemlineata 鞘翅和后翅角质层构建中的关键作用

科罗拉多马铃薯甲虫 (CPB) Leptinotarsa decemlineata是马铃薯 ( Solanum tuberosum ) 的主要害虫，侵扰面积超过 1600 万平方公里^，造成重大经济损失。昆虫角质层形成顶端细胞外基质（ECM）包膜，覆盖暴露的器官，以指导形态发生并提供结构保护。虽然某些几丁质酶( Cht ) 基因已被证明对幼虫发育至关重要，但它们指导成虫翅膀成熟过程中 ECM 重塑的潜在活性仍不清楚。
