ethnomedicines used in trinidad and tobago for urinary problems and diabetes mellitus.this paper is based on ethnobotanical interviews conducted from 1996-2000 in trinidad and tobago with thirty male and female respondents.200617040567
phytoseiidae (acari: mesostigmata) within citrus orchards in florida: species distribution, relative and seasonal abundance within trees, associated vines and ground cover citrus orchards on reduced- to no-pesticide spray programs were sampled for predacious mites in the family phytoseiidae (acari: mesostigmata) in central and south central florida. inner and outer canopy leaves, open flowers, fruit, twigs, and trunk scrapings were sampled monthly between september 1994 and january 1996. vines and ground cover plants were sampled monthly between september 1994 and january 1996 in five of these orchards. the two remaining orchards were on full herbicide progr ...201121499778
comparison of plants used for skin and stomach problems in trinidad and tobago with asian ethnomedicine.this paper provides a preliminary evaluation of fifty-eight ethnomedicinal plants used in trinidad and tobago for skin problems, stomach problems, pain and internal parasites for safety and possible efficacy. thirty respondents, ten of whom were male were interviewed from september 1996 to september 2000 on medicinal plant use for health problems. the respondents were obtained by snowball sampling, and were found in thirteen different sites, 12 in trinidad and one in tobago. the uses are compare ...200717207273

antioxidant activity of herbaceous plant extracts protect against hydrogen peroxide-induced dna damage in human lymphocytes.herbaceous plants containing antioxidants can protect against dna damage. the purpose of this study was to evaluate the antioxidant substances, antioxidant activity, and protection of dna from oxidative damage in human lymphocytes induced by hydrogen peroxide (h2o2). our methods used acidic methanol and water extractions from six herbaceous plants, including bidens alba (ba), lycium chinense (lc), mentha arvensis (ma), plantago asiatica (pa), houttuynia cordata (hc), and centella asiatica (ca).201324279749

low allozymic variation in the bidens pilosa l. complex (asteraceae).bidens alba, b. subalternans, and b. pilosa form a complex group based on their morphological similarities. bidens pilosa l. and b. subalternans dc. are herbs with a wide distribution in agricultural and disturbed areas. bidens alba (l.) dc. varies in size from herb to subshrub and has a coastal distribution. enzyme electrophoresis was used to evaluate genetic diversity in 12 populations of bidens. all but three loci (lap-1, est, and got) were monomorphic. est-1 and got were polymorphic only in ...200516187159
phenylheptatriyne variation in bidens alba var. radiata leaves.variation of phenylheptatriyne (pht) in leaves of bidens alba (linn.) var. radiata (shultz-bip.) was investigated across its florida range, throughout the year, and in response to the photoenvironment. a survey of pht in b. alba leaves was done at 13 sites in florida and three sites throughout the year. pht concentrations differed among populations (p < 0.001), but little of the variation was explained by latitude (r2 = 0.024) or longitude (r2 = 0.022). leaf concentrations of pht fluctuated thro ...200114768817
spider movement, uv reflectance and size, but not spider crypsis, affect the response of honeybees to australian crab spiders.according to the crypsis hypothesis, the ability of female crab spiders to change body colour and match the colour of flowers has been selected because flower visitors are less likely to detect spiders that match the colour of the flowers used as hunting platform. however, recent findings suggest that spider crypsis plays a minor role in predator detection and some studies even showed that pollinators can become attracted to flowers harbouring australian crab spider when the uv contrast between ...201121359183
densities of eggs and nymphs and percent parasitism of bemisia tabaci (hemiptera: aleyrodidae) on common weeds in west central florida.the density of eggs and nymphs of bemisia tabaci (gennadius) biotype b and the percent parasitism of the nymphs were measured from specimens collected on nine species of weeds, commonly found in west central florida during the spring and summer of 2012 and 2013. the weeds were direct seeded in 2012 and grown as transplants in 2013 for randomized complete block design experiments. the leaf area of each whole-plant sample was measured and the b. tabaci density parameters were converted to numbers ...201426462945
evaluating weeds as hosts of tomato yellow leaf curl virus.bemisia tabaci (gennadius) biotype b transmits tomato yellow leaf curl virus (tylcv), which affects tomato production globally. prompt destruction of virus reservoirs is a key component of virus management. identification of weed hosts of tylcv will be useful for reducing such reservoirs. the status of weeds as alternate hosts of tylcv in florida remains unclear. in greenhouse studies, b. tabaci adults from a colony reared on tylcv-infected tomato were established in cages containing one of four ...201526314055
the anticancer effect of protein-extract from bidens alba in human colorectal carcinoma sw480 cells via the reactive oxidative species- and glutathione depletion-dependent apoptosis.bidens alba has been used for healing cuts, injuries, swellings, hypertension, jaundice, and diabetes in some countries. however, the effect of b. alba on human cancer remains poorly understood. the goal of this study was to investigate whether b. alba protein-extract could have an anticancer property against human colorectal cancer. the human colorectal cancer sw 480 cells treated with the protein-extract of b. alba would cause marked dna damages and apoptosis-related cellular morphologies. tre ...200818226850
