Electrophysiological and Behavioral Responses of <i>Dasychira baibarana</i> (Lepidoptera: Lymantriidae) to Tea Plant Volatiles

Abstract Tea black tussock moth, Dasychira baibarana (Matsumura) (Lepidoptera: Lymantriidae), is a devastating pest species of the tea plant in China. Here, we evaluated responses D. to volatiles using gas chromatography coupled electroantennographic detection (GC–EAD), eleclectroantennography (EAG), and Y-tube olfactometer. In total, 11 18 analyzed compounds elicited GC–EAD from test insects. bio-active were further investigated EAG behavioral responses. analysis, male moths had significantly greater four [(Z)-3-hexenyl butyrate, (Z)-3-hexen-1-ol, ocimene benzyl alcohol] than female moths. For females, maximum amplitudes, recorded response linalool, (Z)-3-hexenyl hexanoate (Z)-jasmone. bio-assays, both sexes dose independent. bio-assays responding ocimene, alcohol, (Z)-jasmone at various concentrations. significant observed hexanoate, followed by (Z)-jasmone, alcohol. However, neither sex was sensitive 4 tested compounds, phenyethyl phenylacetonitrile, (E)-nerolidol, indole. The present results showed that influenced behavior moths, which will greatly contribute developing eco-friendly control strategies for baibarana, through application blend or combined with female-produced pheromones.
