Abstract
Makisterone A, a 28-carbon (C-24 alkyl) hexahydroxy steroid, has been identified by mass spectrometry as the major ecdysteroid in last-stage larvae of the large milkweed bug,Oncopeltus fasciatus, a phytophagous hemipteran. Similarly, it is a major molting hormone in 2 phytophagous and 1 predacious species of Hemiptera belonging to the group, Pentatomomorpha. It is not, however, a major ecdysteroid in another group of Hemiptera, the Cimicomorpha, where 1 predacious and 2 hematophagous species contain ecdysone and 20-hydroxyecdysone as their major molting hormones.
