Abstract:

The electroantennogram(EAG) and behavioral responses of female and male beetles of Xylotrechus rusticus to 13 plant volatiles were tested. The female and male adults exhibited very strong EAG responses(P<0.01)to 1 mol·L-1 Eugenol,2-Phenylethanol,furfural,limonene and myrcene. Limonene exhibited lure effect to females adult (P<0.01),when the concentration higher than or equal to 10-3 mol·L-1 and exhibited lure effect to males at 1 and 10-1 mol·L-1 (P<0.01) concentrations. Eugenol exhibited lure effect to females and males at 10-1 and 10-2 mol·L-1 (P<0.01); 2-Phenylethanol showed lure effect to females and males at 10-1 and 10-2 mol·L-1 concentrations(P<0.01). Furfural exhibited repellent effect to females and males at 1 and 10-1 mol·L-1 concentration(P<0.01). Myrcene exhibited lure effect to females and males at 10-1 mol·L-1 concentration(P<0.01). Females and males showed no distinct directional behavior to the other volatiles.

Key words: Xylotrechus rusticus, plant volatiles, lure, repellent, behavioral response
