Juvenile Hormone III plays a critical role in regulating insect development and reproduction. It is widely used in agricultural pest management to disrupt the life cycle of harmful insects. By mimicking the natural juvenile hormone, it prevents larvae from maturing into adults, effectively controlling pest populations. Additionally, it is employed in research to study insect physiology and endocrine systems, providing insights into novel pest control strategies. In sericulture, it is utilized to manipulate the growth and development of silkworms, enhancing silk production. Its applications also extend to the field of entomology, where it aids in understanding the hormonal regulation of insect metamorphosis and behavior.
