Strawberry Guava (Psidium cattleianum) – Prospects for Biological Control
Strawberry guava Psidium cattleianum Sabine (Myrtales, Myrtaceae) was introduced to Hawaii about 1825 and quickly escaped from cultivation. It is now found on all inhabited islands where it is one of the most important forest weeds. The small trees form extremely dense monotypic stands up to 10 m in height. Four insect species were found that have significant deleterious effects and, therefore,...
متن کاملCharacteristics of the Psidium cattleianum (Myrtaceae) Seed Bank in Hawaiian Lowland Wet Forests
Psidium cattleianum Sabine (strawberry guava) is one of Hawai‘i’s most disruptive alien plants. Dense stands can suppress growth and establishment of native species, support high populations of crop-damaging fruit flies, and preclude restoration or management of native forests. Our research investigated factors affecting persistence of P. cattleianum seeds in lowland wet forest soils. We collec...
متن کاملEffect of Psidium cattleianum leaf extract on enamel demineralisation and dental biofilm composition in situ.
OBJECTIVE Previous evaluations of Psidium cattleianum leaf extract were not done in conditions similar to the oral environment. The aim of this study was to evaluate the effect of P. cattleianum leaf extract on enamel demineralisation, extracellular polysaccharide formation, and the microbial composition of dental biofilms formed in situ. DESIGN Ten volunteers took part in this crossover stud...
متن کاملDetermining Subcanopy Psidium cattleianum Invasion in Hawaiian Forests Using Imaging Spectroscopy
High-resolution airborne imaging spectroscopy represents a promising avenue for mapping the spread of invasive tree species through native forests, but for this technology to be useful to forest managers there are two main technical challenges that must be addressed: (1) mapping a single focal species amongst a diverse array of other tree species; and (2) detecting early outbreaks of invasive p...
متن کاملJournal of Dental Science and Therapy Ethanolic Extract of Psidium cattleianum as Intracanal Irrigation: An In vitro Study of Cell Viability
The aim of this study was to evaluate the ethanolic extract of Psidium cattleianum biocompatibility by structural and functional cell viability maintenance. Cell viability was analyzed after 1 h, 3 h, 6 h, 10 h and 24 h of incubation by Exclusion Method with trypan blue and MTT assay, using human mononuclear cells (PBMC) and human periodontal ligament (PDL) cells in culture. Positive control us...
