Consequences of subchronic exposure to ethanolic extract from fruits and leaves of Schinus molle var. areira L. in mice.
Journal of Ethnopharmacology, 2010Co-Authors: Cristina Bras, Alejandra Minetti, Sergio Dominguez, Stella Maris Codón, Adriana Alicia FerreroAbstract:Abstract Aim of the study Several extracts of Schinus molle var. areira L. plant proved to be useful for the treatment of different pathologies and for the control of insect pest. Due to these potential uses, it is necessary to study their safety. In this work, we evaluated the effects of subchronic exposure to ethanolic extracts from leaves and fruits of Schinus molle var. areira in mice. Materials and methods The plant extract was added to the diet at 1 g/kg body weight/day for 90 days. At the end of the exposure, behavioral and functional parameters in a functional observational battery and motor activity in an open field were assessed. Finally, several biochemical and histopathological studies were realized. Results The exposure to extract from leaves produced an increase in the number of rearings in the open field and of urine pools in the functional observational battery. On the other hand, the exposure to extract from fruits produced an increase in the neutrophil count and a decrease in the lymphocyte count and in the total cholesterol levels. None of the exposures affected the different organs evaluated. Conclusions Our results suggest that subchronic exposure to ethanolic extracts from leaves and fruits of Schinus molle var. areira should be potentially useful in the treatment of lipid pathologies and safe to use.

Acute and subacute toxicity evaluation of ethanolic extract from fruits of Schinus molle in rats.
Journal of Ethnopharmacology, 2007Co-Authors: Adriana Alicia Ferrero, Alejandra Minetti, Cristina Bras, Noelia Inés ZanettiAbstract:Ethanolic and hexanic extracts from fruits and leaves of Schinus molle showed ability to control several insect pests. Potential vertebrate toxicity associated with insecticidal plants requires investigation before institutional promotion. The aim of the present study was to evaluate the acute and subacute toxicity of ethanolic extracts from fruits of Schinus molle in rats. The plant extract was added to the diet at 2 g/kg body weight/day during 1 day to evaluate acute toxicity and at 1 g/kg body weight/day during 14 days to evaluate subacute toxicity. At the end of the exposure and after 7 days, behavioral and functional parameters in a functional observational battery and motor activity in an open field were assessed. Finally, histopathological examinations were conducted on several organs. In both exposures, an increase in the arousal level was observed in experimental groups. Also, the landing foot splay parameter increased in the experimental group after acute exposure. Only the subacute exposure produced a significant increase in the motor activity in the open field. All these changes disappeared after 7 days. None of the exposures affected the different organs evaluated. Our results suggest that ethanolic extracts from fruits and leaves of Schinus molle should be relatively safe to use as insecticide.

Taxonomy of Calophya (Hemiptera: Calophyidae) Species Associated with Schinus terebinthifolia (Anacardiaceae)
Florida Entomologist, 2018Co-Authors: Daniel Burckhardt, Rodrigo Diaz, William A Overholt, James P. Cuda, Patricia Prade, Dalva Luiz De Queiroz, Marcelo D. Vitorino, Gregory S. WheelerAbstract:Brazilian peppertree, Schinus terebinthifolia Raddi (Anacardaceae), native to Argentina, Brazil, Paraguay, and Uruguay, is one of the most invasive weeds in Florida. In its native range, at least 4 psyllid species of the genus Calophya (Hemiptera: Calophyidae) are associated with it. All 4 species are monophagous and constitute a likely monophyletic group that induce pit galls, usually on the upper leaf surface. Here we revise the taxonomy of these species, 2 of which are described as new, viz. C. lutea sp. nov. and C. praestigiator sp. nov. Morphological differences between the 4 species are detailed and relevant structures are figured. Keys for adults and the fifth instars are provided for the identification of the 8 species known to induce pit galls on Schinus species.

quarantine host range testing of pseudophilothrips ichini a potential biological control agent of brazilian peppertree Schinus terebinthifolia in north america and hawaii
Entomologia Experimentalis Et Applicata, 2017Co-Authors: Gregory S. Wheeler, Veronica Manrique, William A Overholt, Fernando Mckay, Kirsten DyerAbstract:Brazilian peppertree, Schinus terebinthifolia Raddi (Anacardiaceae), is an invasive weed of natural and agricultural areas of Florida, Hawaii, and Texas (USA). Biological control presents an environmentally safe and cost-effective control method for invasive populations of this weed. Though many potential agents have been tested for specificity, nearly all have been rejected due to a broad host range. However, one species, a thrips Pseudophilothrips ichini (Hood) (Thysanoptera: Phlaeothripidae), shows promise from field observations and quarantine host range tests. A series of no-choice, choice, and multiple-generation tests was conducted on 127 plant taxa (including five mango and four pistachio varieties) from 45 families and 33 orders. In no-choice starvation tests, the thrips fed and produced offspring on the target weed (124 F1 adults per plant), whereas no or few (<4 F1 adults per plant) were obtained on non-target species. The primary exception was another exotic invasive tree Schinus molle L., on which an average 20 F1 thrips adults were produced. No-choice tests indicated that small numbers of F1 offspring were produced on nine other non-target plant species. The numbers of F1 offspring produced on these plants were <3% of those produced on the target weed. In choice tests, on average two or fewer F1 adults were produced on four non-target species tested, compared with 64 F1 adults on the target weed. Multiple-generation tests indicated that three generations of thrips were maintained only on the target weed and S. molle with no differences between these two plant species or across generations. Thus, this thrips species has a narrow host range that includes the two invasive Schinus spp. tested here. If released, the thrips P. ichini will constitute safe and potentially effective biological control of Brazilian peppertree in North America and Hawaii.

comparison of two populations of pseudophilothrips ichini thysanoptera phlaeothripidae as candidates for biological control of the invasive weed Schinus terebinthifolia sapindales anacardiaceae
Biocontrol Science and Technology, 2014Co-Authors: Veronica Manrique, Gregory S. Wheeler, Rodrigo Diaz, Lenin Erazo, Neha Reddi, Dean A Williams, William A OverholtAbstract:Brazilian peppertree, Schinus terebinthifolia Raddi (Sapindales: Anacardiaceae) (hereafter Schinus), is one of the worst invasive species in Florida and Hawaii. The thrips Pseudophilothrips ichini Hood (Thysanoptera: Phlaeothripidae) is being considered as a potential biological control agent of Schinus. Two populations of this thrips were collected in the weed's native range; one from central-east Brazil (Ouro Preto thrips) and a second from north-east Brazil (Salvador thrips). Temperature requirements, adult fecundity and impact on different plant haplotypes by P. ichini were examined in the laboratory. Complete development of thrips from both populations occurred at temperatures ranging from 20 to 30°C. Two approaches were used to model the predicted distributions of the thrips populations in the USA: the physiological model (NAPPFAST) based on cold tolerance and the ecological niche model based on climatic variables (MaxEnt). The physiological model predicted that both populations of P. ichini may est...

Biocontrol Science and Technology, 2012Co-Authors: Marina Oleiro, Marcelo Diniz Vitorino, Gregory S. WheelerAbstract:Abstract The host range of Leurocephala Schinusae Davis & Mc Kay (Lepidoptera: Gracillariidae) was studied to assess its suitability as a biological control agent of Schinus terebinthifolius Raddi (Anacardiaceae), a serious environmental weed in the USA and elsewhere in the world. The host range was determined in the laboratory with adult no-choice oviposition (Argentina and USA) and larval development tests (USA). Seventeen plant species in ten genera were selected based on taxonomic relatedness to S. terebinthifolius, economic importance, and availability. Additional information was obtained by sampling foliage of S. terebinthifolius and six other South American native Anacardiaceae species in north-eastern Argentina. In the laboratory, except for Lithrea molleoides and Spondias mombin, all of the tested species were accepted for oviposition with a marked preference for Rhus aromatica. Incipient mines successfully developed into complete mines, pupae and adults on R. aromatica, Rhus copallinum, Schinus ...

potential allelopathic effects of brazilian pepper Schinus terebinthifolius raddi anacardiaceae aqueous extract on germination and growth of selected florida native plants1
Journal of The Torrey Botanical Society, 2005Co-Authors: E C Morgan, William A OverholtAbstract:Abstract Morgan, E.C., and W.A. Overholt (University of Florida Indian River Research and Education Center, 2199 So. Rock Rd., Ft. Pierce FL 34949). Potential allelopathic effects of Brazilian pepper (Schinus terebinthifolius Raddi, Anacardiaceae) aqueous extracts upon germination and growth of selected Florida native plants. J. Torr. Bot. Soc. 132: 11–15. 2005.—Schinus terebinthifolius, or Brazilian pepper, is an exotic invasive plant found throughout much of peninsular Florida. It rapidly colonizes disturbed areas, often forming dense monotypic stands, and displaces native vegetation. In the current study we examined a potential mechanism by which Brazilian pepper has become a major invader of Florida's ecosystems. In laboratory bioassays and greenhouse experiments, germination and biomass accumulation in two native Florida plant species, Bidens alba and Rivina humilis, were negatively affected by irrigation with aqueous extracts of Brazilian pepper leaves. This study illustrates a potential mechanism t...
