[Schistocerca gregaria allatostatins] Veelaert et al (1996) have described a family of 8 myoinhibiting brain/gut peptides in the desert locust, Schistocerca gregaria. Each of the peptides shows C-terminal amino acid sequence similarity to cockroach and cricket allatostatins and to blowfly callatostatins. The synthetic peptides inhibit the peristaltic movements of the oviduct of S. gregaria. All eight peptides show potent inhibitory effects on juvenile hormone biosynthesis by corpora allata of the cockroach Diploptera punctata, but no allatostatic effects are observed in S. gregaria.
Vanden Broeck et al (1996) have cloned the cDNA
