Electroantennogram response of Semanotus bifasciatus (Matsch.) to volatiles for different ways of extraction from Biota orientalis (L.) Endl.

WANG Ting~1,ZHOU Cheng-gang~(1*),LI Bo~2,SHEN Wei-xing~3,WANG Xin-hua~4(1.College of Plant Protection,Shandong Agricultural University,Taian 271018;2.Taian Bureau of Forestry;3.Management Committee of Mountain Tai;4.Forestry academy of Mountain Tai)  
Two kinds of essential oil were extracted by steam distillation and soxhlet's extraction methods(SEM) from Biota orientalis (L.) Endl.Oddments of Biota orientalis(L.) Endl.and two kinds of essential oil were used to study the Electroantennogram(EAG) response of Semanotus bifasciatus(Matsch.).The result indicated that Semanotus bifasciatus(Matsch.) had EAG response to both essential oil extracted by steam distillation and the oddments,but the response of essential oil was stronger than the oddments'.The response strength was positively correlative with the dosage to a certain range. The oil extracted by SEM couldn't evoke significant response of the insects. Response of female was little stronger than that of male, no difference to the same volatile.
【Key Words】： Semanotus bifasciatus (Matsch.) Biota orientalis(L.) Endl. Essential oil Electroantennogram
