(Verbenaceae var. aculeate). Measurable EAG responses were elicited to all compounds tested; and, mean, pooled EAGs to the sesquiterpene were larger in magnitude than those in response to oxy- and hydrocarbon monoterpenoids. Females were found to be more responsive than males. However, their responses to hydrocarbon monoterpenoids are smaller than those of male moths. Subsequent behavioural analyses in a four-armed olfactometer revealed R-(+)-limonene and (-) germacrene-D to be attractive to female moths. In laboratory cages, these two volatiles also stimulated oviposition and had little repulsive effect on third instar-larvae of the test insect.enMetadata only.
