Costus speciosus is a medicinal plant commonly known as wild ginger distributed in South and Southeast Asian countries. Leaves of this plant are used for ayurvedic treatment regimes in malignancies and mental illness. Rhizome extract from the plant is used to treat malignancies, pneumonia, urinary disorders, jaundice, rheumatism, and diabetes. The goal of this study was to investigate the effec...

the taxonomic affinity of six species of crocus (c, cancellatus subsp. damascenus c. almehensis, c. gilanicus, c. sativus, c.pallassi subsp. haussknechtii,c. speciosus subsp. speciosus) from iran were studied usingdifferent electrophoresis techniques. the similarity index of the species was computed by comparison of protein bands of - corm and seed tissues, and the related dendrogms of affinity...

BACKGROUND Diosgenin, a naturally occurring steroid saponin found abundantly in C. speciosus, is a well-known precursor of various synthetic steroidal drugs that are extensively used in the pharmaceutical industry. METHODS The present study was conducted to evaluate the in vitro anticancer and apoptotic effects on cell proliferation of diosgenin isolated from C. speciosus (Koen.) Sm. RESULT...

in this study, the genetic diversity of 25 iranian saffron genotypes from three species (crocus speciosus, crocus cancellatus and crocus sativus) has been evaluated using 16 morphological traits and rapd marker. c. sativus was different with speciosus in the leaf number per plant, tepal length, flower weight, inflorescence stem height and the stigma length, but had no significant difference wit...

This study addressed biological control of peridomestic Aedes notoscriptus, known to be a highly effective colonizer of tire habitats and a possible vector of Ross River virus. A laboratory trial of the compatibility of the predators Mesocyclops aspericornis and Toxorhynchites speciosus in small container habitats showed that 4th-instar Tx. speciosus did not significantly affect M. aspericornis...

The roles of priority effects and predation in structuring anuran communities have not been considered important in desert environments characterized by highly ephemeral pools and anuran species that breed synchronously. Predation is one mechanism that can set the stage for priority effects to be important, especially in ephemeral pools where resources are limiting and densities are high. We ob...

Chaeridiona mayuri n. sp. infesting ginger (Zingiber officinale Roscoe) and turmeric (Curcuma longa L.) in southern India is described and illustrated. Cheilocostus speciosus ( J. Koenig) C. D. Specht, Globba sessiliflora Sims and Zingiber zerumbet (L.) Smith are reported as additional host plants. Chaeridiona pseudometallica Basu is redescribed and illustrated. A key to the species of Indian C...

The large Japanese field mice (Apodemus speciosus) were captured and kept in stainless cages under a constant condition at 23°C and 14 L: 100 photoperiod, and the growth, development and reproduction were investigated in this species. Modification of feeding condition and nest materials and introduction of a chamber and a running wheel apparatus into each cage first enabled this species to bree...

BACKGROUND Costus speciosus, Cymbopogon citratus, and Tabernaemontana coronaria are herbal plants traditionally used as remedies for symptoms of tuberculosis (TB) including cough. The aims of the present study were to evaluate the in vitro anti-TB activity of different solvent partitions of these plants, to identify the phytochemical compounds, and to assess the effects of the most active parti...

The distributions of American cicada killers (Sphecius) were examined via solicited and museum specimens. S. hogardii occurs in southern Florida and several Caribbean islands. S. speciosus occurs throughout the east coast, southeast, and Midwestern states at high densities, and its range extends much farther west than expected, but not west of the continental divide. S. speciosus appears to be ...
