Abstract
Forty-eight species of cultivated and wild flowering plants in Nebraska were assayed for juvenile hormone (JH) activity. Except for a few plant species, extracts were made of flower heads. Extracts were assayed using pupae of the yellow mealworm, Tenebrio molitor L., as test indicators of JH activity. Examination of over 900 T. molitor adults, treated as pupae, revealed limited evidence of juvenilization. Vestigial urogomphi were present on some adults previously treated as pupae with extracts of 5 plant species. Bioassay of Nepeta cataria (Tourn.) Reichenb, extracts revealed 1 pupal-adult intermediate.Keywords
