Abstract:

[Objectives]  To investigate the bioactivity of six volatile alcohols, aldehydes, alkanes, esters and terpenes, from the plant Caragana kroshinskii (Kom.) to adult Chlorophorus diadema (Motschulsky). [Methods]  Electroantennogram (EAG) and behavioral responses of adult C. diadema to eight different concentrations of 6 single chemicals (1-decanol, nonanal, hexadecane, 2-ethylbutyl acetate, 1-hexadecene and 1-octene), and 20 blends of these chemicals, were tested using an EAG and Y-tube olfactometer. [Results]  Both EAG and olfactory behavioral responses of C. diadema adults to single volatile components and blends were basically the same. Six of the 20 blends, S, P, Q, H, I and B, were significantly attractive to female and male beetles (P<0.05). [Conclusion]  (1) Blended volatiles are more attractive than single compounds; (2) Compound S, which was comprised of 1-decanol, hexadecane and nonanal, was the most attractive substance tested; (3) A mixture of four components (1-decanol, hexadecane, nonanal and 1-hexadecene) can serve as a basic of attractant for C. diadema in further studies.
