title: Biological activity of yangambin on the postembryonic development of Chrysomya megacephala (Diptera: Calliphoridae).
abstract: Phytochemicals endowed with hormonal, antihormonal, or toxic activity are potential agents for insect control. Thus, we became interested in testing Brazilian plant metabolites on Chrysomya megacephala (F.) (Diptera: Calliphoridae), a public health menace that is one of the most prevalent flies in Brazilian urban areas. We tested the lignan yangambin, from the leaves of Ocotea duckei Vattimo (Lauraceae). Topical treatment of eggs and first instars with yangambin as well as feeding larvae a yangambin-treated diet resulted in inhibition of postembryonic development, morphological alteration, and oviposition reduction.
