Terrestrial plants have been demonstrated to be sources of antimalarial compounds. In Cuba, little is known about antimalarial potentials of plant species used as medicinals. For that reason, we evaluated the antimalarial activity of 14 plant species used in Cuba as antimalarial, antipyretic and/or antiparasitic. Hydroalcoholic extracts were prepared and tested in vitro for the antimalarial act...

Congress grass (Parthenium hysterophorus L., family Asteraceae) is found generally in agricultural and vacant lands across the globe. This study investigated fatty acids elemental profiles of different parts including roots, stem leaves P. response to seasonal variation. The analysis acid were determined both winter summer seasons. root, stem, powder subjected extraction with acetone, water, ch...

The leaves of parthenium (Parthenium hysterophorus L.) were extracted in ethanol and toxicity the extract was examined on khapra beetle (Trogoderma granarium Everts) larvae. Four concentrations (2, 4, 6 8 µL mL-1 acetone) applied directly larvae Petri dishes. Toxicity recorded after 12, 24 36 h. All had considerable effect mortality At highest concentration (8 mL-1), observed 57%, 72% 78% h, re...

Parthenium weed is an invasive species of economic importance worldwide. Native to the American tropics, infestation ability a new habitat largely influenced by environmental factors. Despite invasion in Malaysia dated back 2013, investigation on its ecological behavior still lacking. Hence, extensive studies two predominant Malaysian populations were executed. In Petri dish seed bioassay, germ...

BACKGROUND Parthenium dermatitis is a major problem in urban and rural India. Patients with severe allergic rhinitis due to exposure to pollens of parthenium are reported to have parthenium specific IgE and IgG antibodies. Parthenium induces contact dermatitis by Type IV hypersensitivity and allergic rhinitis by Type-I hypersensitivity. AIMS The study was undertaken to detect Type-I and Type-...

Data collected during our on-going studies on the phytodiversity in the Upper Bari Doab Region of Punjab, show an inverse relationship between the level of phytodiversity and incidence of the congress grass-Parthenium hysterophorus. The open vegetation at Khiala Khurd (31 degrees -33' N-74 degrees .18' E), a site typical of the whole region, has a Shannon-Weaver index value of 2.544, which is f...

Glyphosate has been the most intensely herbicide used worldwide for decades, and continues to be a single tool for controlling weeds in woody crops. However, the adoption of this herbicide in a wide range of culture systems has led to the emergence of resistant weeds. Glyphosate has been widely used primarily on citrus in the Caribbean area, but a study of resistance in the Caribbean islands of...

Pest Risk Assessments (PRAs) routinely employ climatic niche models to identify endangered areas. Typically, these models consider only climatic factors, ignoring the 'Swiss Cheese' nature of species ranges due to the interplay of climatic and habitat factors. As part of a PRA conducted for the European and Mediterranean Plant Protection Organization, we developed a climatic niche model for Par...
