Ananas are used as food plants by the larvae of some Lepidoptera species including "Batrachedra comosae", which feeds exclusively on "A. comosus". The word "Ananas" is derived from the Guarani name for the pineapple, via Portuguese. In most Old World languages, pineapple is called "ananas. "Ananas" species contain both bromelain and papain to which they owe their meat-tenderizing properties. The fruit and roots are used by some peoples as anti-inflammatory, proteolytic agent, and a root decoction for diarrhea. The biggest producers of pineapples in 2014 were Costa Rica (2.9 million tonnes), Brazil (2.6) and the Philippines (2.5). Ananas Ananas is a
Boletellus ananas named by Moses Ashley Curtis as "Boletus ananas" in 1848, based on specimens he found near the Santee River, in South Carolina. In 1909, William Murrill described the new genus "Boletellus" and made "Boletellus ananas" the type species. According to Murrill, the taxon "Boletus isabellinus", described by Charles Horton Peck in 1897 from specimens collected in Ocean Springs, Mississippi, is a synonym of "B. ananas"; Peck described this species from undeveloped specimens. Wally Snell later doubted Murrill's conclusion in a 1933 publication; he considered the differences in the spore structure too great to consider the species conspecific with "B. ananas",
