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

Agromyzidae; Diptera; Molecular characterization; Persian clover; Soybean Stem Fly

The soybean stem fly (Melanagromyza sojae) is a widely distributed and highly damaging soybean pest, recently introduced to Brazil and neighboring countries. The bioecology of this pest under South American growing conditions is largely unknown, including how infesting populations survive throughout the winter. Fly larvae collected in August 2019 from Persian ... more

Biological control; Differential display reverse transcriptase; Expressed sequence tag; Nematophagous; Single nucleotide polymorphisms

The technology of mRNA-based differential display reverse transcriptase-polymerase chain reaction (DDRT-PCR) was used to detect a 246-bp differentially expressed fragment from the nematophagous fungus Arthrobotrys oviformis when young mycelia were induced with the round worm Haemonchus contortus. The fragment was converted into an expressed sequence tag (EST) through ... more

The relationships between schistosomiasis and its intermediate host, mollusks of the genus Biomphalaria, have been a concern for decades. It is known that the vector mollusk shows different susceptibility against parasite infection, whose occurrence depends on the interaction between the forms of trematode larvae and the host defense cells. These cells are called amebocytes or ... more

Biological control; PCR; Phytopathogenic fungi; Trichoderma

Seven fungal isolates were identified as pan-global Hypocrea/Trichoderma species, from section Trichoderma, on the basis of their morphology. These species were H. lixii/T. harzianum and H. orientalis/T. longibrachiatum. PCR-based markers with primer M13 (core sequence of phage M13) and internal-transcribed spacer sequences of ribosomal ... more

Biological control; COI; Genetic structure; Intraspecific divergence; Morphological variation; Placusa pinearum

Placusa pinearum, a newly described beetle species found living in pine shoot tunnels bored by the pine tip moth, Dioryctria rubella (Pyralidae), has potential as a vector to transport biological agents for controlling this moth pest of pine trees because of the high degree of niche overlap (co-occurrence) between them. In order to help determine the suitability of ... more

Endophytic microorganisms consist of fungi, bacteria, and actinomycetes that play important roles in the process of plant adaptation to the environment. Currently, the natural associations between microorganisms and plant species are being explored for a large number of biotechnological applications. In this study, 122 endophytic bacteria were isolated from 5 cultivars of Musa ... more

Cotesia flavipes (Cameron) is a parasitoid wasp used in the biological control of the sugarcane borer (Diatraea saccharalis) (Fabr., 1794). Studies on the genetic diversity of C. flavipes are hampered by the lack of highly polymorphic molecular markers. In this report, a set of 11 microsatellite loci were ... more

Cultivar selection; Genotype x crop year interaction; Glycine max; Selection index

Soybean is one of the main sources of foreign exchange credits for Brazil in the agricultural sector. There is increasing interest in growing this leguminous crop, especially in the southern region of Minas Gerais, due to its importance as an alternative for crop rotation with maize. In this respect, the study of the adaptability of new cultivars to the region is indispensable so as to ... more

Agronomic trait; Asian rust; Glycine max; Indirect selection

Soybean (Glycine max L.)-breeding programs aim to develop cultivars with high grain yields and high tolerance to Asian soybean rust (Phakopsora pachyrhizi). Considering that the traits targeted for breeding are mainly quantitative in nature, knowledge of associations between traits allows the breeder to formulate indirect selection strategies. In this study, we ... more
