Electrophysiological Responses of the Monolept ahieroglyphica (Motschulsky) to 13 Volatile Compounds

【Objective】 To screen out active substances to Monoleptahieroglyphica (Motschulsky). 【Methods】 The electroantennogram (EAG) technique was used to determine the electrophysiological responses of the female and male M. hieroglyphica to 13 kindsofcotton, corn and adult fecalvolatiles. 【Results】 The response of M. hieroglyphica male and female to Hptene, Nerolidol, Phellandrene, β-Pinene, trans-2-Hexenal, trans-2-hexen-1-ol, Dioctyladipate, Leaf alcohol were relatively obvious, and to Nonoic acid, Nonadecane and Heptadecane were not obvious.The highest response of female to Leaf alcohol was 2.306 mV, and male to β - Pinene was 2.309 mV. Females are more sensitive to Hexadecane and Humulene than males. 【Conclusion】 Among 13 volatiles, the response of M. hieroglyphica females to leaf alcohol is the most sensitive, the response of M. hieroglyphica a males to β-pinene is the most sensitive.
