We have screened 80 plant species of the Spanish Mediterranean flora for ovicidal, JH-mimic, anti-JH, and toxic activity against insects. Fractions of 12 species have shown ovicidal activity against Leptinotarsa decemlineata. Twenty-one species have given evidence of JH-mimic activity by alteration of Tribolium castaneum metamorphosis. Thirty-two extracts or fractions had toxic effects on Oncopeltus fasciatus nymphs, and seven have produced some alterations in the fertility of the treated insects as to be considered as prospective anti-JH effects. A compound has been isolated from Chrysantemum coronarium D4 fraction inducing precocious metamorphosis on O. fasciatus. Tentative NMR, ME, and IR spectroscopy identification gives no molecular resemblance to the precocenes molecular structures, so it may present reasonable leads for development of new insect growth regulators.
