Diagnostics floristic and phytosanitary of species tree present in the parish Francisco Eugenio Bustamante, Maracaibo, Zulia state, Venezuela

Abstract:

A floristic and plant diagnostic trees was done in Francisco Eugenio Bustamante County, Maracaibo, Zulia state, Venezuela, through collections of botanical specimens in situ and direct visual evaluation during March, April and May of 2011. The material collected was processed using standard techniques of herborization. A total of 43 species were identified and grouped in 38 genera and 24 families, being 44.18% of the species introduced and 55.82% Native American. The family Fabaceae had the highest number of species with five Mimosoideae, four Caesalpinioideae and one Faboideae. The predominant species, given the number of times that were collected were Azadirachta indica A. Juss. (Nim), Swietenia mahogani (L.) Jacq., Peltophorum pterocarpum (DC.) K. Heyne, Mangifera indica L. Tabebuia rosea (Bertol.) DC., Ficus microcarpa L. F., Bucida buceras L. and Manilkara zapota (L.) P. Royen. The trees found in Francisco Eugenio Bustamante County were mainly distributed in gardens and squares, and less frequently on sidewalks, sports fields and some dividing islands of avenues. Some individuals of P. pterocarpum (33%), T. rosea (27%) and “Árbol Sagrado de la India” (25%) were affected by termites (Nasutitermes sp.). In addition, several specimens of M. indica (55%) showed “guts” or “boom” (Fusarium decemcellulare) and anthracnose in fruit. The species reported in this inventory are a significant floristic element of ornamental and landscape use in the county.
