Sipyloidea sipylus

On the other hand, the defensive secretions of Sipyloidea sipylus and of Megacrania tsudai, two phasmid insects originating from Asia, contain volatile compounds, and, in both cases, the whole secretion has a repellent activity [180,181]. 

The composition and biosynthesis of chitin have been studied in insects such as mosquitoes, cockroaches, honeybees, silkworms. Drosophila melanogaster, Extatosoma tiaratum, Sipyloidea sipylus in terrestrial crustaceans such as Armadillidium vulgare, Porcellio scaber, and in nematodes (Anantaraman and Ravindranath 1976, Carlberg 1982, Veronico et al. 2001, Nemtsev et al. 2004, Moussian et al. 2005, Tauber 2005, Paulino et al. 2006, Hild et al. 2008). The composition and structure of their organic matrices are different from each other.
