中文摘要： 昆虫变态发育使得昆虫成为地球陆地上种类最多、数量最大、分布最广、生活环境最多样化的一群生物。变态使昆虫在其生命周期中的不同发育时期表现出完全不同的形态、结构、功能和生活习性的变化，有利于昆虫迁飞转移，扩大其求偶交配、生活和生存环境空间。昆虫变态发育的变化是长期自然环境适应、协同进化的结果，受激素、营养和基因的精确调控。本文简要介绍了昆虫变态的类型、激素调控、营养调控和基因调控方面的研究进展，以及研究昆虫变态发育的科学和应用意义。
英文摘要： Metamorphosis has allowed insects to become the biggest group of land organisms on the planet in terms of species number, overall numbers as well as to have a global distribution and huge diversity of living habits. Metamorphosis allows insects to have completely different morphological features, structures, functions and living habits at different life-stages,
which greatly expands their behavioral and ecological range. Metamorphosis is a result of long-term adaption to the natural environment and co-evolution. Metamorphosis is accurately regulated by insect hormones, nutrients and gene expression. This review provides a brief introduction to the types of metamorphosis, its regulation by hormones, nutrients and genes, and thescientific and practical significance of research on metamorphosis.
