La mayoria de las especies de "guaguas" bland as presentes en Cuba han sido estudiadas por su relacion con las plantas de interes economico, sin embargo, en los sistemas naturales la fauna de estos insectos es casi desconocida. En este trabajo se dan a conocer tres nuevos registros de coccidos para Cuba, recolectados en ecosistemas naturales, los cuales corresponden a Coccus capparidis (Green, 1904), Saissetia miranda (Cockerell & Parrot, 1899) y Toumeyella liriodendri (Gmelin, 1790), y se relacionan sus plantas hospedantes con nuevos registros para estas especies.
Phenacoccus parvus Morrison is recorded from Florida for the first time. Specimens were collected at Miami on Cestrum diurnum (Solanaceae),l-IX-1883 by J. Frankel, and on an unidentified plant of the family Apiaciae (Umbelliferae), 4-XI-1983, by D. Barger. These records are also the first for the continental US. Phenacoccus parvus material from Hawaii on Sida fallax has been examined. This mealybug was described from the Galapagos Islands. Williams and Cox (1984) synonymized the name P. surinamensis with P. parvus. This species has been recorded from the West Indies, Central America, and South America on many hosts (Williams and Granara de Willink 1992). It has been recorded recently from Africa, the tropical South Pacific area, Australia, and southern Asia. The distribution was mapped, with references, by CAB International Institute of Entomology (1990).
Se dan a conocer nuevos registros de Coccoidea para Cuba, en los cuales se incluye el genera Parasaissetia Takahashi (Coccidae) y las especies Saissetia neglecta DeLotto (Coccidae) y Eriococcu,s dubius Cockerell (Eriococcidae). Ademas se relacionan las plantas hospedantes, con nuevos registros para estas especies.
Paracoccus marginatus Williams and Granara de Willink, here called the papaya mealybug, was first detected in the United States in Hollywood, Florida in 1998. By the end of 1998 it was found in four localities in the state and has since spread to nine localities in five counties. This mealybug appears to have moved through the Caribbean area since its 1994 detection in the Dominican Republic. The pest is reported to cause serious damage to tropical fruit, especially papaya, and has been detected most frequently, in Florida, on hibiscus. It is now known from Antigua, Belize, the British Virgin Islands, Costa Rica, Guatemala, Mexico, Nevis, Puerto Rico, St. Barthelemy, St. Kitts, St. Martin, and the US Virgin Islands. Hosts include: Acacia sp.(Luguminosae), Acalypha sp.(Euphorbiaceae), Ambrosia cumanensis (Compositae), Annona squamosa (Annonaceae), Carica papaya (Caricaceae), Guazuma ulmifolia (Sterculiaccea), Hibiscus rosa-sinensis (Euphorbiaceae), Hibiscus sp. (Euphorbiaceae), Ipomoea sp. (Convolvulaceae), Manihot chloristica (Euphorbiaceae), Manihot esculenta (Euphorbiaceae), Mimosa pigra (Lugiminosae), Parthenium hysterophorus (Compositae), Persea americana (Lauraceae), Plumeria sp. (Apocynaceae), Sida sp. (Malvaceae), Solanum melongena (Solanaceae). The species is believed to be native to Mexico andlor Central America.
