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.
具有激素、抗激素或毒性活性的植物化学物质是控制昆虫的潜在药剂。因此，我们开始对测试巴西植物代谢产物对大头金蝇（双翅目：丽蝇科）的作用感兴趣，这种公共卫生害虫是巴西城市地区最常见的苍蝇之一。我们测试了来自桂叶樟（樟科）叶片的木脂素洋甘菊素。用洋甘菊素对卵和一龄幼虫进行局部处理，以及给幼虫喂食经洋甘菊素处理的食物，均导致胚胎后发育受到抑制、形态改变和产卵量减少。
