bemisia tabaci (gennadius) (hemiptera: aleyrodidae), is one of the most important pest of vegetable and fruit crops. this polyphagous pest has a range of natural enemies including the parasitoid eretmocerus mundus (merect) (hymenoptera: aphelinidae). to determine the molecular profile and taxonomic status of iranian isolates of e. mundus, parasitized b. tabaci samples were collected from cotton...

Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae), is one of the most important pest of vegetable and fruit crops. This polyphagous pest has a range of natural enemies including the parasitoid Eretmocerus mundus (Merect) (Hymenoptera: Aphelinidae). To determine the molecular profile and taxonomic status of Iranian isolates of E. mundus, parasitized B. tabaci samples were collected from cotton...

We compared patterns of intraspecific polymorphism of two markers with contrasting modes of evolution, nuclear ribosomal DNA (rDNA) and mitochondrial DNA (mtDNA), in the lung fluke, diploid and triploid Paragonimus westermani from three geographical regions of Korea. The genetic distances between three populations of Korean diploid and triploid P. westermani showed no significant difference in ...

A new genetic variation and potential haplotype of Bactericera cockerelli was identified based on the analysis mitochondrial region Cytochrome Oxidase subunit I two populations from greenhouses in Villa Unión, Durango Saltillo, Coahuila, Mexico. found base 247 a 500 bp amplified mtCOI gene, this change implies substitution an adenine (A) to Guanine (G), mutation detected insects collect their p...

To determine the molecular phylogenic location of Plagiorchis muris, 28S D1 ribosomal DNA (rDNA) and mitochondrial cytochrome C oxidase subunit I (mtCOI) were sequenced and compared with other trematodes in the family Plagiorchiidae. The 28S D1 tree of P. muris was found to be closely related to those of P. elegans and other Plagiorchis species. And, the mtCOI tree also showed that P. muris is ...

Hibiscus rosa-sinensis is a widely grown evergreen valuable medicinal, ornamental species planted in India. Scale insects are small herbivorous found on all continents and they serious sap sucking pests of many plants. These scale undetectable due to their tiny size, basic morphology, polyphagous feeding nature. Hence, the management these become concern across globe. To afford prospective solu...

The pontellid calanoid Labidocera rotunda Mori, 1929 is relatively widespread in the inshore surface waters of East Asia. In this study, some heteromorphic specimens have been observed with extreme morphological discrepancies in the female, including the genital double-somite, the second urosomite, the caudal rami, and the fifth leg. To evaluate the validity of species assignment of the morphol...

this study pursued the molecular identification of fish species from processed products for human consumption which, a priori, belonged to nine species. dna barcoding using direct sequencing of about 650 bp of the mitochondrial gene cytochrome oxidase subunit i (coi) revealed incorrect labeling in the three alaska pollack samples (11% of all samples). substitution of fish species constitutes se...

Phylogenetic relationships among all described species (total of 5 taxa) of the shrimp genus Penaeus, were examined with nucleotide sequence data from portions of mitochondrial gene and cytochrome oxidase subunit I (COI). There are twelve commercial shrimp in the Iranian coastal waters. The reconstruction of the evolution phylogeny of these species is crucial in revealing stock identity that ca...
