ABSTRACT
Gymnoclytia
occidua
(Walker), and
Euclytia
flava
(Townsend)] were attracted to this volatile and, therefore, were using it as a host-finding kairomone. In a sixth species,
E. obscurus
(Palisot de Beauvois), which extends from the Greater Antilles and Mexico into the southern United States (Froeschner 1988), this volatile was one of two that were produced in abundance by males; the other was tentatively identified as methyl 2,6-dimethyltetradecanoate (Aldrich et al. 1991), later corrected to methyl 2,6,10-trimethyltridecanoate (Aldrich 1995a, 1996; Aldrich et al. 1994).
