Sesquiterpenoid hormones are widely present in arthropods and play crucial roles growth, molting reproduction. Methyl farnesoate (MF) functions similarly to juvenile hormone (JH) crustaceans, playing a broad regulatory role their growth development. However, compared insects, systematic studies on the mechanisms of sesquiterpenoid crustaceans still lacking. Neocaridina denticulata, small freshwater shrimp known for its fast high reproductive capacity ease maintenance, is an ideal model organism crustacean research. To investigate effects MF development N. feeding experiments were conducted changes at phenotypic molecular levels examined. In this experiment, basal diet was used as control, with 40 μg/kg, 4 μg/kg 0.4 added feed. The MF-enriched diets fed denticulata body length measured every 10 days. After days activities amylase (AMS), lipase (LPS), trypsin (Try), superoxide dismutase (SOD), malondialdehyde (MDA) glutathione peroxidase (GSH-PX) assessed, transcriptome analysis performed. We found that showed initial inhibitory effect (day 30), but by day 40, low-concentration group exhibited significantly enhanced indicating dose- time-dependent effect. Activities AMS, LPS, Try SOD generally decreased, whereas MDA GSH-PX activity increased after exposure. Moreover, transcriptomic revealed regulated various biological processes including metabolism immune responses. High concentration appeared restrict via modulation exoskeleton-related cellular stress genes. Medium optimizing metabolic signaling pathways. Low preferentially up-regulated genes related muscle function, potentially supporting locomotion competitive ability. This study provides new insights into mechanism potential applications aquaculture future.
