Boeve, Jean-Luc published the artcileSecretion of the ventral glands in Craesus sawfly larvae, HPLC of Formula: 110-34-9, the publication is Biochemical Systematics and Ecology (2008), 36(11), 836-841, database is CAplus.
The secretion from ventral glands of Craesus alniastri, Craesus septentrionalis, and Craesus latipes (Hymenoptera, Tenthredinidae, Nematinae) was analyzed by GC-MS. The terpenoid dolichodial was the major compound in the 3 species. A few other terpenoids, several hydrocarbons, esters, aldehydes, and the aromatic compound benzaldehyde were also detected. Among the Nematinae the occurrence of dolichodial is restricted to Craesus and several species of the closely related genus Nematus. Craesus comprises ∼20 species. Their larvae are generally gregarious and brightly colored, and they possess highly developed ventral glands. Field tests show that the gregarious habit of C. septentrionalis larvae is an active process. This manuscript covers the chemotaxonomy, biosynthesis, and bioactivity of dolichodial, and the interactions between glandular secretion and appearance of larvae.
