Plants of Senna occidentalis (sin. Cassia occidentalis) with mosaic symptoms were collected near a soybean (Glycine max) field where some plants exhibited symptoms of mosaic and blistering. A preliminary examination of leaf tissue from diseased S. occidentalis by electron microscopy revealed the presence of pinwheel inclusions as well as long flexuous particles, indicating the presence of a pot...

The western flower thrips, Frankliniella occidentalis (Pergande), is an invasive species and the most economically important pest within the insect order Thysanoptera. F. occidentalis, which is endemic to North America, was initially detected in Kunming in southwestern China in 2000 and since then it has rapidly invaded several other localities in China where it has greatly damaged greenhouse v...

The effect of lyophilised aqueous extract of Telfairia occidentalis (TO) on induced cyanide toxicity in rats was investigated. Twenty 3-week old male wistar albino rats were randomly distributed into one control and three treatment groups of five rats each: control group (group1), group treated with 3mg/kg body wt of cyanide only (group2), group treated with 3mg/kg body wt. each of cyanide and ...

thrips specimens were collected in the year 2014 on different ornamental plants from mahallat (markazi province), iran. in this study, 11 species in six genera and three different families of thysanoptera were collected and identified. the scientific names of thrips species are as follow: melanthrips knechteli, m. pallidior, frankliniella intonsa, f. occidentalis, microcephalothrips abdominalis...

The deep-water crangonid Parapontophilus occidentalis (Faxon, 1893) is endemic to the eastern Pacific and has been reported from Mexico to Chile, in depths of 837-4082 m. Material collected off the west coast of the Baja California Peninsula (BCP) during the TALUD XV, XVI and XVI-B cruises consists of a series of 136 specimens (M:F = 1:3.6) with 30 % of ovigerous females. The material examined ...

Reverse transcriptase-quantitative polymerase chain reaction (RT-qPCR) is a reliable technique for measuring and evaluating gene expression during variable biological processes. To facilitate gene expression studies, normalization of genes of interest relative to stable reference genes is crucial. The western flower thrips Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae), the mai...

The fiddler crab Austruca occidentalis is a dominant species in mangrove forests along the East African coast. It enhances soil aeration and, through its engineering activities, makes otherwise-inaccessible food available for other marine organisms. Despite its importance, the habitat of A. occidentalis is threatened by human activities. Clearing the mangroves for salt farming and selective log...

Quantitative real-time PCR (qRT-PCR) is a powerful technique for measuring and evaluating gene expressions during different biological processes. To facilitate gene expression studies, normalization with respect to stable housekeeping genes (HKGs) is mandatory. T he western flower thrips, Frankliniella occidentalis (Thysanoptera: Thripidae), the main vector of Tomato spotted wilt virus (TSWV), ...

The knowledge of a species' population structure is essential for the development of adequate conservation actions as well as for the understanding of its evolution. The population structure is unknown in all species of the Genus Psammodromus, including the Western Sand Racer (Psammodromus occidentalis; a recently described species), the Edward's Sand Racer (P. edwardsianus) and the Spanish San...
