Abstract

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)-2-Hexenal , (E)-2-Hexen-1-ol, acetate, Cyclopropane, 1-ethyl-2-heptyl, Hexadecane, (E)-3-Octen-1-ol, acetate, (E)-5-Decen-1-ol, acetate, 2-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)-2-Hexanal were the most abundant compounds and constituted approximately 90% of the total content. Minimal amounts of Octane were detected in males and Hexadecane in females.
