Does mechanical damage on soybean induces the production of flavonoids? Anais da ABC (AABC)
SILVA,PAULO LUIZ DA; CORDEIRO,GLÁUCIA; SILVA,CAROLINA R. DA; BARROS,RAFAEL A.; SILVA,CAMILA R. DA; ZANUNCIO,JOSÉ C.; CAMPOS,WELLINGTON G.; OLIVEIRA,MARIA G.A..
Abstract The response of plants to grazing includes the production of chemical defense compounds such as proteases inhibitors and secondary metabolites as flavonoids, which makes them less palatable to feeding and negatively affecting the physiology of insects. The aim of this study was to evaluate the phytochemical response of soybean cultivars (Glycine max (L.) Merrill) resistant (IAC-17, IAC-24) and susceptible (IAC-P1) to insects after mechanical damage. These cultivars were mechanically injured, and after 24 hours samples of these plants were analyzed by HPLC to identify and quantify flavonoids. The flavonoids daidzein, quercetin, and rutin were quantified, with the highest concentration of daidzin in soybean cultivars after mechanical damage. Rutin...

Molecular identification of three species of Oncideres (Coleoptera: Cerambycidae) using RAPD markers Anais da ABC (AABC)
CORDEIRO,GLÁUCIA; CUNHA,MARINA S. DA; SILVA,CAROLINA R. DA; JORGE,ISAAC R.; DERGAM,JORGE A.; FERREIRA,PAULO S.F..
Abstract: Twig girdlers have a short adult life and a long larval stage (up to one year in some species). This fact, together with lack of morphological traits to identify the species from the larval stage, poses obstacles for the taxonomic identification and characterization of the many twig girdlers found in the wild. To solve this matter, Random Amplified Polymorphic DNA (RAPD) molecular markers have been applied to identify some insect species and to determine species boundaries. The aim of this study was to identify three species of Oncideres using the RAPD technique. Adults and larvae of O. saga, O. ocularis and O. ulcerosa were collected in Minas Gerais, Brazil. Two RAPD primers were used (OPA-05 and OPB-13), which produced different electrophoretic...
