Table 2.
Tentatively identified hydrocarbons (H1 to H25) in the cuticle and tergal glands of Z. cucumis. Note that the percentages of hydrocarbons in this table are calculated using the sum of both volatile compounds and hydrocarbons. MM: molar mass; RI: Kovats retention index calculated by using n-alkane series; RI (ref): RI from the literature; MC: male cuticle; FC: female cuticle; MTG: male tergal gland; FTG: female tergal gland.
