[Effects of different elicitors on olfactory response and oviposition selection of Dendrolimus superans (Butler)].
This paper studied the behavioral responses of Dendrolimus superans larvae and adults to Z-jasmone, methyl jasmonate (MeJA) and methyl salicylate (MeSA), and to Larix gmelinii seedlings treated with different elicitors including mechanic wounding, insect feeding, jasmonic acid (JA), salicylic acid (SA), Z-jasmone, MeJA, MeSA, and JA + SA. The results showed that D. superans larvae were repelled by MeJA and MeSA at the concentrations of 0.1%-10% V/V. L. gmelinii seedlings were induced resistance by wounding, JA, MeJA, Z-jasmone and MeSA, which decreased the feeding selection of D. superans larvae. D. superans adults exploited evident electroantennogram (EAG) responses to Z-jasmone and MeSA, and the sensitivity of the females was enhanced with the increasing concentration of Z-jasmone and MeSA. Significantly low amount of eggs was observed on the L. gmelinii seedlings treated with test elicitors.
