“…A recent study on crustaceans confirmed that orcokinin 1, orcokinin 2, allatostatin B, orcomyotropin and YRPRP4 all showed significant changes after feeding, indicating that these neuropeptides are directly involved in appetite regulation [23,30]. Although bursicon β has been characterized in multiple crustaceans, its function in appetite regulation has not been confirmed [31]. Evidence in Drosophila revealed that bursicon β plays an important role in food intake regulation [32], and it can be speculated that bursicon β also plays a similar role in the food intake regulation of L. vannamei.…”

Litopenaeus vannamei, with high plant protein acceptance and high global aquaculture production, is a potential species for rapeseed meal application. However, rapeseed meal has been associated with anorexia in fish, and whether the same occurs in L. vannamei remains unknown. This study demonstrated the effects of rapeseed meal on the feeding and anorexigenic endocrine of L. vannamei based on feeding behavior and transcriptomics. Soybean meal was replaced with fermented rapeseed meal (50%), and a significant increase in remaining diet and dietary discard was observed with a significant reduction in dietary visits. Transcriptome analysis revealed that the pathways involved in rapeseed meal-induced anorexia mainly included signal transduction, the digestive system, the sensory system, the endocrine system, phototransduction–fly, the thyroid hormone signaling pathway and pancreatic secretion. Moreover, this study further analyzed and identified seven neuropeptides involved in rapeseed meal-induced anorexia, and it explored the complex expression regulation strategies of these neuropeptides. In summary, this study confirmed through feeding behavior that rapeseed meal causes anorexia in L. vannamei, and it identified seven neuropeptides that were closely related to the anorexia process.

Egg development neurosecretory hormone (EDNH), a hormone that stimulates vitellogenesis in mosquitoes, was purified 10,000-fold from the mosquito Aedes aegypti. The purification procedure included chromatography o n hydrophobic, ion exchange, and gel filtration columns, and preparative electrophoresis to give an almost homogeneous preparation. The hormone i s a polypeptide monomer of molecular weight of 18,700 f 500 as determined from SDS electrophoresis and gel filtration chromatography. Using lowpressure chromatography throughout the purification procedure, the hormone was recovered at a high yield (39%). The amount of EDNH in a mosquito is about 0.6-1.6 ng, corresponding to 32-85 fmol.Injection of purified EDNH into female mosquitoes resulted in the conversion of [14C]cholesterol into labeled ecdysone and 20-hydroxyecdysone which were separated and identified using thin-layer chromatography and h igh-performance I iq u id ch romatography separation procedures.Egg development and vitellogenin synthesis were also induced when EDNH was injected into several mosquito species, indicating that the hormone is not species-specific. This report is the first to show that a purified preparation of EDNH has both steroidogenic and a gonadotropic effects on female mosquitoes.
