Ultrasound-assisted extraction versus traditional Soxhlet apparatus for the obtention of polyphenols, carotenoids and tocopherols from Tagetes erecta L. flowers.

Background: Tagetes erecta L., commonly known as American marigold, serves as a food plant used for the extraction of carotenoids such as lutein, employed both as culinary ingredient in certain dishes and for its ornamental and medicinal applications. Two extraction techniques, Soxhlet and ultrasound-assisted extraction (UAE), were used on two cultivars (yellow and orange) of T.

Ultrablack color in velvet ant cuticle.

We studied the ultrastructure of the ultrablack cuticle in , an enigmatic and visually striking species of velvet ants (Hymenoptera, Mutillidae). Using a combination of scanning electron microscopy (SEM), transmission electron microscopy (TEM), confocal laser scanning microscopy (CLSM), and optical spectroscopy, we conducted a comprehensive analysis of the cuticle to elucidate its unique optical properties. SEM imaging provided a detailed surface morphology, while TEM provided insights into the internal structure.

Two new genera of Neotropical Dasymutillini (Hymenoptera, Mutillidae, Sphaeropthalminae): Goncharovtilla gen. nov. from Brazil and Dasyphuta gen. nov. from Panama.

Two new monotypic genera are described within the tribe Dasymutillini: Goncharovtilla Williams, Bartholomay & Lopez, gen. nov. (type species: G.
