Chitin is a major component in the extracellular matrix of insects, and its metabolism largely affects insect development and molting. As essential degradative enzymes, chitinases are encoded by multiple genes that differ in size, expression pattern and function in insects. However, our limited knowledge on the functions of different chitinases in Agrotis ipsilon has prevented our application of new technologies to target these genes as new pest management strategies.

Agrotis ipsilon 几丁质酶家族基因的鉴定和基于 RNAi 的功能分析

甲壳素是昆虫细胞外基质的主要成分，其代谢在很大程度上影响昆虫的发育和蜕皮。作为必需的降解酶，几丁质酶由昆虫中大小、表达模式和功能不同的多个基因编码。然而，我们对Agrotis ipsilon中不同几丁质酶功能的了解有限，阻碍了我们应用新技术来靶向这些基因作为新的害虫管理策略。
