Chemical Analysis of the Metathoracic Scent Gland of Eurygaster maura (L.) (Heteroptera: Scutelleridae)

Eurygaster maura (L.) (Heteroptera: Scutelleridae) is one of the most devastating pests of wheat in Turkey. The metathoracic scent gland secretions of male and female E. maura were analyzed separately by gas chromatography-mass spectrometry. Twelve chemical compounds, namely, Octane, n-Undecane, n-Dodecane, n-Tridecane, (E)-۲-Hexenal , (E)-۲-Hexen-۱-ol, acetate, Cyclopropane, ۱-ethyl-۲-heptyl, Hexadecane, (E)-۳-Octen-۱-ol, acetate, (E)-۵-Decen-۱-ol, acetate, ۲-Hexenoic acid, Butyric acid, and Tridecyl ester were detected in both males and females. These compounds, however, differed quantitatively between the sexes. In both females and males, n-Tridecane and (E)-۲-Hexanal were the most abundant compounds and constituted approximately ۹۰% of the total content. Minimal amounts of Octane were detected in males and Hexadecane in females.
