DNA barcoding is a fast and reliable tool for species identification, and has been successfully applied to a wide range of freshwater fishes. The limitations reported were mainly attributed to effects of geographic scale, taxon-sampling, incomplete lineage sorting, or mitochondrial introgression. However, the metrics for the success of assigning unknown samples to species or genera also depend ...

The phylogenetic relationship between the whitefly Bemisia afer (Priesner & Hosny) (Hemiptera: Aleyrodidae) from China and other populations among the world were analyzed based on the mitochondrial cytochrome oxidase I (mtCOI) gene. Phylogenetic analysis of mtCOI sequences and those of reference B. afer sequences showed that the populations of the species could be separated into 5 clades (I-V)....

Abstract Bactrocera zonata is a fruit tree pest that typically attacks and causes heavy damage in production using its sucking mouth. Researchers have started to distinguish them through molecular characterization sequencing control this pest. Mitochondrial genes such as COI (mtCOI) are commonly used barcoding for identifying eukaryotes counting insects. In the current study, mtCOI gene has bee...

Tessaratoma javanica (Thunberg) (Hemiptera: Tessaratomidae) an important sucking pest of litchi is studied for supplementing information on its biology, morphometrics of life stages and mtCOI (DNA barcodes). More details generated on the study add to the description of stages namely egg, 1st to 5th nymphal instars and adults. The evaluation of morphometrics of the life stages reveal that the pr...

Members of the whitefly Bemisia tabaci species complex cause millions of dollars of damage globally and are considered one of the world's most invasive species. They are capable of causing extensive damage to major vegetable, grain legume and fiber crops. All member of the species complex are morphologically identical therefore, data from the partial mitochondrial cytochrome oxidase subunit I (...

After the 2004 discovery of the Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae) Q biotype in the United States, there was an urgent need to determine its distribution. As part of a coordinated country-wide effort, an extensive survey of B. tabaci biotypes was conducted in Florida, with the cooperation of growers and state and federal agencies, to monitor the introduction and distribution of...

The whitefly Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae) is a cryptic species complex that contains some of the most damaging pests in tropical and subtropical regions. Recent studies suggested that this complex is composed of at least 24 distinct species. We use the approach from these studies to consider the identity of B. tabaci in Argentina. Previous studies have suggested the prese...

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...

Whiteflies are economically important plant pests that cause damage to crops worldwide. This study aimed update the status of whiteflies in Jordan by combining classical morphological identification and DNA markers using mitochondrial cytochrome oxidase I (mtCOI) gene. Over course three consecutive years, 111 were collected from different geographical regions hosts Jordan. The results showed th...
