PBAN-INDUCED SEX PHEROMONE BIOSYNTHESIS IN HELIOTHIS PELTIGERA : STRUCTURE, DOSE, AND TIME-DEPENDENT ANALYSIS
A structure-activity relationship study of Hez-PBAN was performed with respect to its pheromonotropic activity, using Heliothis peltigera as the test animal. The activity of N- and C-terminally… Expand
