Sugarcane white leaf disease is caused by plant pathogenic phytoplasmas that are transmitted to the plant by the leafhopper Matsumuratettix hiroglyphicus (Matsumura). To determine whether there are other insect vectors that transmit this disease pathogen, leafhopper species in sugarcane, Saccharum officinarum L., fields in northeastern Thailand were monitored by using light traps. Sixty-nine le...

in this study brown algae, sargassum glaucescens and that found plenteously in persian gulf and bushehr coast, were collected and hot water extracts of them were lyophilized. f. indicus (11.32±1.20 g), after two weeks adaptation in shoghab research station dependent to iran shrimp research center, isrc, were immersed in seawater (39 ppt and 25±1 c○) containing hot-water extract of brown algae, ...

this study was conducted to investigation and determine of cadmium (cd) concentration in the liver of platycephalus indicus (flathead) in minab, qeshm island and khamir port (persian gulf). moreover, the effect of season (winter and summer) and sex (male and female) on cd concentration in flathead were investigated. cd concentration sampling was done in two station (minab, qeshm island and kham...

DNA-based molecular markers for differentiation of five penaeid shrimps (Penaeus monodon, P. semisulcatus, Feneropenaeus merguiensis, Litopenaeus vannamei and Marsupenaeus japonicus) were developed based on polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and single-stranded conformation polymorphism (SSCP) of 16S ribosomal (r) DNA. Differentiation of P. monodon, P....

Genetic structure and demographic history of shrimp Feneropenaeus chinensis were examined using sequence data from portions of the mitochondrial cytochrome c oxidase I (COI) gene. Samples of 91 individuals were collected from 5 localities over most of the species’ range in the Yellow Sea and Bohai Sea. Variability was detected at a total of 20 nucleotide sites, defining 20 haplotypes of COI in ...
