| mortality of leishmania major in phlebotomus papatasi caused by plant feeding of the sand flies. | the plant feeding of phlebotomus papatasi and the effects of plant diets on the leishmania major infections were investigated. plant-fed flies had small free particles and membranous shreds in their gut that were stained by calcofluor as cellulosic plant tissues. they were found in 34.0% of the female and 14.3% of the male sand flies following feeding on the caper plant (capparis spinosa). no plant residues were found in 54 females that had been fed on plant-derived honeydew secretions of aphis ... | 1994 | 8304569 |
| heavy metals and arsenic uptake by wild vegetation in the guadiamar river area after the toxic spill of the aznalcóllar mine. | on 25 april 1998, approximately 4.5 hm(3) of pyritic sludge, containing 5000 mg of as kg(-1) among other pollutants, was spilled into the agrio and guadiamar rivers and the surrounding agricultural areas (aznalcóllar, seville, southern spain). many trace metals such as pb, cu, zn, cd, tl, sb and as reached the doñana national park, the largest wetland area in europe, affecting soils, different plant and animal species. in order to recuperate the affected lands by employing plants capable of accu ... | 2002 | 12126811 |
| ecology and behavior of pezothrips kellyanus (thysanoptera: thripidae) on citrus. | the most common thrips species found in cyprus citrus orchards between 2003 and 2008 were pezothrips kellyanus (bagnall) (thysanoptera: thripidae), frankliniella occidentalis (pergande) (thysanoptera: thripidae), and thrips tabaci (lindeman) (thysanoptera: thripidae). only pezothrips kellyanus, kelly's citrus thrips (kct) causes feeding damage on citrus fruits in cyprus. kct adults prefer to concentrate mostly in the northern and eastern sides of both lemon and grapefruit canopies. the attractiv ... | 2010 | 20214367 |
| species identification of plant tissues from the gut of an. sergentii by dna analysis. | there are three commonly used assays to identify plant material in insect guts: the cold anthrone test for fructose, the cellulose staining test for visualizing plant tissue and gas chromatography for seeking unique sugar content profiles. though sugar and cellulose tests can distinguish between the general sources of sugar meal (nectar versus tissue), they cannot identify the species of plant sources. even gas chromatography profiles can be problematic; there are reported instances of intra-spe ... | 2010 | 20382098 |
