Aggregation pheromone from airborne

The chiral alcohol, 2-methyl-4-octanol, was identified as an aggregation pheromone from airborne volatiles produced by male and females of the sugarcane weevil Sphenophorus levis. Enantiomeric resolution by GC with a chiral column showed that the natural alcohol possessed the S configuration. The alcohol elicited aggregation behavior among adults. ... 

Two recent examples of isolation are gentisyl quinone isovalerate [185] and a novel p-lactone, vittatalactone [(3R,4R)-3-methyl-4-(l,3,5,7-tetramethyloctyl)oxetan-2-one [118]. The fornier is a female sexual pheromone which was isolated from the German cockroach Blattella germanica), and the latter is an aggregation pheromone which was isolated from collections of airborne volatile compounds from feeding male striped cucumber beetles, Acalymma vittatum.
