A compound with significant insect juvenile hormone activity was isolated from the plant, Macropiper excelsum . The chemical structure was determined by spectral methods to be 1‐(3,4‐methylenedioxyphenyl)‐trans‐3‐decene(l), and confirmed by synthesis. The hormonally active substance applied topically to last (fifth)‐instar nymphs of the milkweed bug ( Oncopeltus fasciatus ) induced a supernumerary metamorphosis at 30 μg. Higher doses were toxic.
