Theobroma cocoa and chocolate. "Theobroma" species are used as food plants by the larvae of some moths of the genus "Endoclita", including "E. chalybeatus", "E. damor", "E. hosei" and "E. sericeus". The larvae of another moth, "Hypercompe muzina", feed exclusively on "Theobroma cacao". An active ingredient of cacao, theobromine, is named for the genus. Theobroma Theobroma is a genus of flowering plants in the mallow family, Malvaceae, that is sometimes classified as a member of Sterculiaceae. It contains roughly 20 species of small understory trees native to the tropical forests of Central and South America. The generic name is derived from
Cacao yellow mosaic virus Cacao yellow mosaic virus Cacao yellow mosaic virus (CYMV) is a virus in the family Tymoviridae that infects cacao trees in Sierra Leone. CYMV, like other "Tymoviridae" are non-enveloped viruses, surrounded by a capsid approximately 30 nanometers wide. The viral capsid has T = 3 symmetry. "Tymoviridae" have positive-sense single-stranded RNA genomes approximately 6 kilobases long. In the cacao tree, CYMV infection leads to the appearance of large circular yellow blotches on the leaves. Infected trees are not killed or severely inhibited. CYMV has only been found in Sierra Leone where it primarily infects the cacao tree "Theobroma cacao". However,
