title = "Antibacterial activity of 4-oxo-(E)-2-hexenal from adults and nymphs of the heteropteran, Dolycoris baccarum (heteroptera: Pentatomidae)",
abstract = "We identified 4-oxo-(E)-2-hexenal (4-OHE) as a common component of the secretion from both Dolycoris baccarum nymphs (66:5 ± 34:7 μg/bug) and adults (87:4 ± 48:0 μg/bug) by GC/MS. We also found that this compound inhibited the growth of bacteria starting at 10 μg. The stronger antibacterial activity of 4-OHE than that of (E)-2-hexenal and (E)-2-octenal might be explained by the reactivity of αβ-unsaturated aldehydes with nucleophilic molecules.",
