Soybean stem fly (SSF), Melanagromyza sojae is an important pest in soybean growing regions of the Old World, and recently has been confirmed in soybean areas in Brazil, Paraguay and Bolivia. In the regions where it is endemic, the management of M. sojae is performed by using resistant varieties, chemical insecticides and natural control carried ... more

Genetic variability; Microsatellites; Molecular characterization; Musa spp

Microsatellite markers have been widely used in the quantification of genetic variability and for genetic breeding in Musa spp. The objective of the present study was to evaluate the discriminatory power of microsatellite markers derived from ‘Calcutta 4’ and ‘Ouro’ genomic libraries, and to analyze the genetic variability among 30 banana accessions. Thirty-eight markers were ... more

Babesia vogeli; Canine babesiosis; Molecular characterization; Northern Brazil

Babesiosis is an infectious hemolytic disease that occurs worldwide, and is caused by a protozoan of the Babesia genus (Apicomplexa). Little is known about this genus; therefore, this study conducted a molecular characterization of Babesia spp in naturally infected dogs in northern Brazil. Blood samples were collected from 172 dogs from metropolitan Belém, and screened ... more

Forage crop; Genetic diversity; ISSR markers; Molecular characterization

Cratylia argentea (Desv.) Kuntze (Fabaceae) is a drought-tolerant, perennial legume found primarily in Brazil, Bolivia, and Peru. The shrub is well adapted to acid soils and exhibits high productivity and nutritional value, characteristics that would favor its use as a dry season animal forage supplement in semiarid regions. In plant improvement programs, the production of elite ... more

Indigenous Brazilian fruit tree; Molecular characterization; Population structure

Some species of Anacardium (Anacardiaceae) produce fruits and pseudofruits that are smaller than those of the common cashew (Anacardium occidentale) and, for this reason, are known collectively in Brazil as “cajuí”. Despite their economic value in the food market and their important environmental and ecological functions, cajuí trees remain ... more

Genetic resources; Ginger; ISSR; Molecular characterization

Ginger (Zingiber officinale Roscoe) is a self-incompatible plant and has high rates of infertility; its genetic diversity only occurs via processes of mutation and natural selection. Since ginger is important as a condiment and as an herbal medicine, understanding its diversity to a greater degree can contribute both to its conservation and to its use in ... more

Biosecurity; Haplotype diversity; Invasive pest; mtDNA COI; Soybean Stalk Fly; Soybean Stem Fly

Soybean Stem Fly (SSF), Melanagromyza sojae (Zehntner), belongs to the family Agromyzidae and is highly polyphagous, attacking many plant species of the family Fabaceae, including soybean and other beans. SSF is regarded as one of the most important pests in soybean fields of Asia (e.g., China, India), North East Africa (e.g., Egypt), parts of Russia, and South East Asia. Despite ... more

Leafminers (Liriomyza sativae) are the main melon (Cucumis melo L.) pests in Northeast Brazil, which is the main region for the production and export of the fruit in Brazil. Of the integrated management strategies available, genetic resistance is the best method of preventing damage by these insects. The aim of this study was to select sources of resistance to leafminers in melon germplasm. ... more

We provided the first scientific record of Melanagromyza sojae (Zehntner, 1900), through molecular characterization of partial mtDNA COI gene, that confirms the occurrence of this pest in Paraguay. Previously reported in Brazil, an outbreak of larvae of M. sojae known as the soybean stem fly (SSF) that belongs to the family Agromyzidae, was also noted in soybean fields from the Canindeyú, Alto ... more
