Female parasitoids were tested with volatiles and extracts derived from their host beetle. Behavioral assays (Y-olfactometer bioassay and circle arena) demonstrated the response of female parasitoids to odors from host plants damaged by beetle larvae and from their excreta. When available contact cues were additionally provided, the parasitoids showed particularly strong preferences for samples of fresh brown frass of larval beetles. To confirm the electroantennograms (EAG) activity of identified compounds, analyses were repeated with a synthetic blend composed predominantly of compounds in the crude extracts that had revealed apparent electrophysiological activity. Antennal responses to four monoterpenes and three oxygenated monoterpenes were among the strongest, which indicated their potential for use in development of semichemial-based management of the beetle.
