Global Invasive Species Database online data sheet. Locations within which Psidium cattleianum is naturalised include Australia, tropical and southern Africa, New Zealand, south-eastern USA and many oceanic islands with warm climates. Its flowers grow either individually or in clusters of three, and each flower has five petals. pp. Smith, C. W. 1985. Thus, some control efforts involve removal and control of invasive fauna. 33. Control is generally best applied to the least infested areas before dense infestations are tackled. The skin is often removed for a sweeter flavour. Although P. cattleyanum has select economic uses, it is considered the most invasive plant in Hawaii. The yellow-fruited variety, P… A population study and distribution of strawberry guava (Psidium cattleianum) in Hawaii Volcanoes National Park, Hawaii. Psidium cattleyanum (World Plants : Psidium cattleianum), commonly known as Cattley guava, strawberry guava or cherry guava, is a small tree (2–6 m tall) in the Myrtaceae (myrtle) family. Guayaba fresa (Psidium cattleianum): fotos e información (identificada) (Leer más...) bueno , tengo un frutal precioso , tiene unos pequeños frutos, son raros, el arbol es precioso y tiene hojas todo el año, las hojas son parecidas ala camelia, siempre cargaditos de frutos , en estos momentos el arbol tiene mucha flor ...si tengo suerte y alguien me dice su nombre y asta pronto It bears fruit when the plants are between 3 and 6 years old. Some varieties have a yellow skin. Its bark is grey to reddish-brown and peels readily. Henderson, L. (2001).  The wood of the tree is hard, compact, durable, and resistant, and is used for lathe work, tool handles, charcoal, and firewood.  This biological control approach is used because certain insects cause damage to P. cattleyanum in a way that either prevents the tree from reproducing or kills them outright. Arbusto de Psidium cattleianum Figura 27. These flowers are borne singly in the leaf upper forks. 1989. Kuntze Myrtus verrucosa Berg Psidium cattleianum var. (2010). "Strawberry Guava - Psidium cattleianum - Details - Encyclopedia of Life", "Biological Control of Strawberry Guava in Hawaii", "PCA Alien Plant Working Group - Strawberry Guava (Psidium cattleianum)". Accessed March 2011. This activity was undertaken as part of the BioNET-EAFRINET UVIMA Project (Taxonomy for Development in East Africa).  It works by focusing wood removal, burning, and other management efforts in the designated efforts. Not listed as a noxious weed by the state or governments in Kenya, Tanzania and Uganda. Guajava cattleyana (Sabine) Kuntze Guajava obovata (Mart. leaves, flowers and young fruit (Photo: Rosa Say, CC BY-NC-ND), immature fruit (Photo: John Mauremootoo, CC-BY-NC), mature fruit (Photo: Forest & Kim Starr, CC-BY), infestation, Mauritius (Photo: John Mauremootoo, CC-BY-NC), Psidium cattleianum var. Brown, R. L., C. S. Tang, and R. K. Nishimoto. The species is named in honour of English horticulturist William Cattley. Seedling and clonal recruitment of the invasive tree Psidium cattleianum: Implications for management of native Hawaiian forests. Psidium cattleianum (tree, shrub). Usambara Invasive Plants - Amani Nature Reserve - www.tropical-biology.org/research/dip/species.htm.  Once such species, the sawfly (Haplostegus epimelas), attacked commercially produced guava plants in addition to invasive P. Psidium cattleianum produces a lot of fruit with each seed containing up to though usually less than 70 seeds. Its ubiquity in damaged ecosystems further muddles management due to its high dispersal from these less-sensitive habitats to more fragile habitats. Impact of alien plants on Hawaii's native biota. Eugenia ferruginea Sieber Eugenia ferruginea Sieber ex C.Presl Eugenia oxygona Koidz. , The whole fruit can be eaten as both the thin skin and juicy interior are soft and tasty. The yellow variety bears even more heavily than the red and generally has larger fruit. Univ. State of Hawaii. , P. cattleyanum reproduces through setting seed and through cloning. The leaves are dark green, opposite, elliptic to oblong and up to 8 cm long. The Psidium cattleianum is now a weed in many parts of the tropics where it has quickly adapted to a variety of climates (Henderson 2001). " The red-fruited variety, P. cattleyanum var. Master's thesis. The best form of invasive species management is prevention.  P. cattleyanum is prevalent in both undisturbed and highly disturbed roadside habitats in its invasive range.  Additionally, its seeds have many health benefits, including antioxidant, anti-inflammatory, and antimicrobial properties in addition to a high amount of Vitamin C., P. cattleyanum occurs primarily in mesic tropical rainforest environments at an elevation of up to 1300m, but is found primarily below 800m. Strawberry Guava (Psidium cattleianum) – Prospects for Biological Control. Psidium cattleianum can form dense thickets that exclude native vegetation and reduce native species regeneration. It is now highly prevalent in tropical rain forest ecosystems due mainly to accidental transportation and its invasive plant properties. Natl. However, these uses cannot compensate for this plant's overall negative impacts.  However, some insects cannot be used due to the potential for certain species to attack more than P. It is in leaf all year, in flower in May.  It was introduced in Hawaii as early as 1825 to create an agricultural market for its fruits, but it has yet to be a commercially viable product. Its white flowers (15-25 mm across) have five petals and numerous stamens. C. Wikler, J. Pedrosa-Macedo, M. Vitorino, M. Caxambú, C. Smith. , A variety of management strategies have been applied to P. cattleyanum management efforts due to its ubiquity and the various ways it spreads. BioNET-EAFRINET Regional Coordinator: email@example.com, Introduced, naturalised or invasive in East Africa, www.tropical-biology.org/research/dip/species.htm. It has invaded humid areas such as rainforests on tropical islands especially in the Pacific and Indian Oceans where it displaces native species and threatens their survival.  The Brazilian Scale is a potential biological control agent used in Florida, and Hawaii.  Despite the great threat that P. cattleyanum poses to many tropical ecosystems, some studies indicate that isolated groups can be totally eradicated after three to four years of proper management applications, such as cutting and burning mature individuals and applying herbicide to stumps. The seeds of which are dispersed by birds and mammals. (1999). littorale (O. Berg) Fosb., Psidium littoraleRaddi, Strawberry guava, cattley guava, cherry guava, Chinese guava. Strawberry Guava: Not All Green Is Good.  Its native range is restricted to the Amazonian Basin in Brazil, but it has established in many other tropical areas of similar characteristics. , P. cattleyanum has modest economic impacts in Hawaii due to its edible fruits and beads that are made by tying individual fruits together. , Preliminary research suggests that P. cattleyanum is allelopathic, as its roots have been found to inhibit the growth of at least two other plant species when soil pH was not a factor..  Though native to Brazil, it is now distributed throughout many tropical regions. La guayaba es una de las frutas más ricas en vitamina C , ya que algunas variedades poseen cinco veces más que la naranja. The red-fruited variety, P. cattleyanum var. They are shiny and leathery in texture. Its genus name Psidium comes from the Latin psidion, or "armlet. Growth inhibition from guava root exudates. K. McCook-Russella, M. Nairb, P. Faceya, C. Bowen-Forbesa. Various chemicals can be used to control Psidium cattleianum through basal bark (painting herbicide onto the bark) and cut stump applications. Plant Protection Research Institute Handbook No. Psidium cattleianum is a small erect evergreen bush or tree growing to 7.5 m, although often much smaller.  Its invasive quality may be explained by a high amount of genetic variation, as variants of different fruit colors cluster at different elevations. Its genus name Psidium comes from the Latin psidion, or "armlet." Psidium indicum Bojer.  However, products made from P. cattleyanum are not commercially available because of a lack of market and the heavy presence of fruit flies. Clonally produced suckers tend to have a greater leaf area. ex DC. Native to Brazil where it is known as araçá (ara-SAH) and adjacent tropical South America, it is closely related to common guava (P. guajava), and like that species is a widespread, highly invasive species in tropical areas throughout the Indian and Pacific Oceans. Seedling and clonal recruitment of the invasive tree Psidium cattleianum: implications for management of native Hawaiian forests. (2016). It has been nominated as among 100 of the "World's Worst" invaders by the IUCN Invasive Species Specialist Group and it has been listed as an invader in South Africa as a Category 3 invader in South Africa (no further planting is allowed - except with special permission - nor is trade in propagative material. Psidium cattleianum de 10 años de edad y 1´5 metros de altura cargado de frutos a principios de octubre. Lowe S., Browne M., Boudjelas S., De Poorter M. (2000). El Guayabo Amarillo un árbol muy aromático, que ya era cultivado por los nativos antes de la llegada de los españoles. Huenneke, L.F. and P. M. Vitousek. Hawaii Coop. It is also naturalised on Lord Howe Island, Norfolk Island and Christmas Island (Navie 2004; Queensland Herbarium 2008). Agnes Lusweti, National Museums of Kenya; Emily Wabuyele, National Museums of Kenya, Paul Ssegawa, Makerere University; John Mauremootoo, BioNET-INTERNATIONAL Secretariat - UK. 1983.  It is able to propagate quickly due to the spread of its seed, which occurs as its seeds fall and as birds and feral pigs transport fruits, as well as through its root sprouts. Cattley guava, cherry guava, Chinese guava, pineapple guava, porpay, purple guava, purple strawberry guava, red cherry guava, red guava, red strawberry guava, small guava, strawberry guava Suitable pH: acid, neutral and basic (alkaline) soils. Psidium cattleyanum (World Plants : Psidium cattleianum), commonly known as Cattley guava, strawberry guava or cherry guava, is a small tree (2–6 m tall) in the Myrtaceae (myrtle) family. cattleyanum, is commonly known as purple guava, red cattley guava, red strawberry guava and red cherry guava. Some components of an integrated management approach are introduced below. GISD (2010). 584. cattleyanum, is commonly known as purple guava, red cattley guava, red strawberry guava and red cherry guava. , P. cattleyanum does not dominate plant communities in its native range. Bark Photograph by: Starr, F. & K. Image credit to Australian National Botanic Gardens. pp. , Feral pigs and non-native birds contribute to the spread of P. cattleyanum via seed dispersal. (2012). Larger plants can be uprooted but it is labour intensive and the plant can resprout if root fragments are left in the ground. It is hardy to zone (UK) 10 and is frost tender. It is considered to be the worst invasive plant species in several islands in the Indian Ocean.  Its ability to thrive in a variety of different habitats under many different ecological conditions threatens native flora of many different habitat types. Additionally, feral pigs may ingest the fruits, whose seeds reach the soil in the scat of the feral pigs. The species is named in honour of English horticulturist William Cattley. The yellow form tends to be a bit less hardy and therefore is found at slightly lower elevations. Its fleshy fruit (2-3 cm across) turn purplish-red in colour when mature and are crowned with the some of the old flower parts. The seeds are small and white in colour. Psidium littorale Raddi. , Cattley guava is sporadically naturalised in coastal areas of Queensland and northern New South Wales. Psidium ferrugineum C.Presl. , Psidium cattleyanum is a small, highly-branched tree that reaches a maximum height of 13 meters, although most individuals are between 2 and 4m. If in doubt consult an expert. The editors are not aware of records of the presence of P. cattleianum in Kenya and Uganda, though this does not necessarily mean that it is absent from these countries. US Forest Service. Locations within which Psidium cattleianum is naturalised include Australia, tropicaland southern Africa, New Zealand, south-eastern USA and many oceanic islands with warm climates. Alien weeds and invasive plants.  However, continued follow-up management is necessary indefinitely after a period of high-intensity restoration. The species is hermaphrodite (has both male and female organs). This fact sheet is adapted from The Environmental Weeds of Australia by Sheldon Navie and Steve Adkins, Centre for Biological Information Technology, University of Queensland. Host specificity of Tectococcus ovatus (Hemiptera: Eriococcidae), a potential biological control agent of the invasive strawberry guava, Psidium cattleyanum (Myrtales: Myrtaceae), in Florida. , P. cattleyanum is often associated with invasive feral pigs The two species are often found near each other, most likely because feral pigs aid in the spread of P. cattleyanum. Hawaii, Honolulu. This renders the fruits inedible soon after they are picked. The plant is indispensable for mixed planting in reforestation of reclaimed and protected areas in Brazil.  But, it is invasive due to its robust tolerance to many different environments. We recognise the support from the National Museums of Kenya, Tropical Pesticides Research Institute (TPRI) - Tanzania and Makerere University, Uganda. Most of the proposed insects infect the tree with bud or leaf galls, effectively preventing fruit growth or photosynthesis. littorale is variously known as yellow cattley guava, yellow strawberry guava, yellow cherry guava, lemon guava and in Hawaii as waiawī. Psidium cattleianum (Guayabo fresa) Ugni molinae 'flambeau' Ugni molinae (Murtilla) FRUTOS DEL BOSQUE. P. cattleianum is naturalized in many tropical and subtropical countries after introduction as an ornamental or a fruit tree. Univ. The precise management measures adopted for any plant invasion will depend upon factors such as the terrain, the cost and availability of labour, the severity of the infestation and the presence of other invasive species. Huenneke, L. (1990). "Strawberry Guava - Psidium cattleianum - Overview - Encyclopedia of Life".  The yellow-fruited variety, P. cattleyanum var. It was introduced to many of the areas it now invades due to human usage as a crop for its edible fruit. The wood is useful for poles. 2007. ex DC.) Eugenia pseudovenosa H.Perrier Eugenia urceolata Cordem. When using any herbicide always read the label first and follow all instructions and safety requirements.  P. cattleyanum has smooth, grey to reddish-brown bark, with oval to elliptical leaves that grow to 4.5 cm in length. Se le conoce como guayabo peruano, arazá rojo, guayabita del Petú o güisaro, es natural de América del Sur, especialmente de Perú.
