Abstract

Methyl farnesoate, [methyl (2E,6E)-3,7,11-trimethyldodeca-2,6,10-trienoate (1)] has not been thought be present in the hemolymph of insects, although it is the immediate biosynthetic precursor of the circulating insect hormone juvenile hormone III (methyl (2E,6E)-10,11-epoxy-3,7,11-trimethyl-2,6-dodecadienoate) (2). Compound 1 was identified from the hemolymph obtained from five orders of insects. Identification of 1 from the American bird grasshopper was facilitated using both electron impact and chemical-ionization GC-MS, GC-FTIR, and 2D NMR techniques. The identifications from other insects were made using GC-MS, and the amounts of all were quantified using LIM-CI-GC-MS. The ratios of 1 and 2 varied in these insects during different developmental stages. The present results underscore the need for further studies on methyl farnesoate (1) as a circulating hormone in insects.
