lectins and toxins in the plant diet of phlebotomus papatasi (diptera: psychodidae) can kill leishmania major promastigotes in the sandfly and in culture. | leishmania major promastigotes are agglutinated and die in their vector, phlebotomus papatasi, after the sandflies feed on some plants that are found in their natural habitat. in in-vitro assays, extracts of ricinus communis (euphorbiaceae), capparis spinosa (capparaceae), prosopis farcta (mimosaceae) and tamarix nilotica (tamaricaceae) agglutinated and killed the parasites. this activity could be inhibited by specific carbohydrates, indicating that it was the result of various lectins in the ex ... | 1999 | 10656036 |
characterization of root-nodulating bacteria associated to prosopis farcta growing in the arid regions of tunisia. | diversity of 50 bacterial isolates recovered from root nodules of prosopis farcta grown in different arid soils in tunisia, was investigated. characterization of isolates was assessed using a polyphasic approach including phenotypic characteristics, 16s rrna gene pcr--rflp and sequencing, noda gene sequencing and mlsa. it was found that most of isolates are tolerant to high temperature (40°c) and salinity (3%). genetic characterization emphasizes that isolates were assigned to the genus ensifer ... | 2011 | 21359955 |
differential attraction of aedes albopictus in the field to flowers, fruits and honeydew. | sugar is the main source of energy for the activities of mosquitoes; however, information on the vital sugar feeding of aedes albopictus in the field is scanty and often anecdotal. using glue traps and baits, we evaluated the attraction of ae. albopictus to 28 different, potential sugar sources. control traps were baited with either sugar-water solution or water alone, and since there was no significant difference between these controls, the water control was used as the standard for comparison. ... | 2011 | 21310142 |
assessment of plant tissue feeding by sand flies (diptera: psychodidae) and mosquitoes (diptera: culicidae). | plant tissue feeding by culex pipiens molestus (forskål) was determined by identification of plant residues, differentially stained with calcofluor, in dissected mosquito guts. such residues were found in 42.3% of 286 field-caught mosquitoes. a method for determination of plant tissue feeding from specific sources is described. before feeding branches were suffused with calcofluor stain which binds to plant cell walls; stained residues of this tissue in the insect gut are indicative of feeding. ... | 1995 | 8551514 |
paenibacillus prosopidis sp. nov., isolated from the nodules of prosopis farcta. | a bacterial strain, designated pw21(t), was isolated from root nodules of prosopis farcta in tunisia. phylogenetic analysis based on 16s rrna gene sequences placed the isolate into the genus paenibacillus, with its closest relatives being paenibacillus glycanilyticus ds-1(t) and paenibacillus castaneae ch-32(t) with identity values of 96.9 %. dna-dna hybridization measurements showed values of less than 25 % with respect to these two species. the isolate was a gram-variable, motile and sporulati ... | 2010 | 19897617 |
plants used for the treatment of diabetes in israel. | in an extensive ethnobotanical survey (130 informants) of the medicinal plants of israel, 16 species were found to be used for hypoglycaemic treatments. the list includes achillea fragrantissima (forssk.) sch.-bip, ammi visnaga (l.) lam, atriplex halimus l., capparis spinosa l., ceratonia siliqua l., cleome droserifolia (forssk.) del., eryngium creticum lam., inula viscosa (l.) ait., matricaria aurea (loefl.) sch.-bip, origanum syriaca l., paronychia argentea lam, prosopis farcta (banks et sol.) ... | 2006 | 3613607 |
relative attraction of the sand fly phlebotomus papatasi to local flowering plants in the dead sea region. | sugar is the main source of energy for the daily activities of sand flies. considering its importance, there is surprisingly little information on sugar meal specific sources and sand fly attraction to plants, particularly in the field. in this study, we first needed to develop an effective sand fly trap that would be suitable for mass screening of potentially attractive flowering plants. next, we used this trap to screen a total of 56 different flowering plant species and five plant species soi ... | 2011 | 21366774 |
