A chemical investigation of a female gland-like organ of the European chafer, Rhizotrogus majalis, with GC-EAD has resulted in the identification of a few female-specific high EAD active compounds with male antennae. These chemicals did not exhibit obvious attractancy in a preliminary field trap test. However, it does not rule out other behavioral roles, such as short-range courtship. Further studies are needed to clarify their function.
