Does mechanical damage on soybean induces the production of flavonoids?
Silva, Paulo Luiz da; Cordeiro, Gláucia; Silva, Carolina R. da; Barros, Rafael A.; Silva, Camila R. da; Zanuncio, José C.; Campos, Wellington G.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-...
Ocorrência de Compsosoma perpulchrum em eucalipto, no estado de Minas Gerais, B...
Cordeiro, Gláucia; Anjos, Norivaldo dos; Magistrali, Iris Cristiane; Lemes, Pedro GuilhermeAs espécies do gênero Eucalyptus são as mais utilizadas no setor florestal graças, principalmente, ao seu rápido crescimento e à sua boa adaptação às diferentes condições de solo e de clima, no Brasil. Entretanto, alguns insetos podem-se tornar pragas dessa espécie florestal, como é o caso de Compsosoma perpulchrum (Coleoptera: Cerambycidae), que apresenta registro roletando árvores de E. grandis no Paraná. Est...
Sexual dimorphism in the twig girdler Oncideres ocularis Thomson (Coleoptera: C...
Lemes, Pedro Guilherme; Anjos, Norivaldo dos; Jorge, Isaac Reis; Cordeiro, GláuciaThe ability to distinguish gender among insects is essential to their study and management. The objective of this work was to find sexual dimorphism between males and females of Oncideres ocularis Thomson, 1868 based on their external morphology. Twenty-seven morphometric variables from the body of males and females of this beetle were measured. The length of body, elytra, length and width of the head, and leng...
Biologia de Oncideres ulcerosa (Germar, 1824) em Ficus benjamina L. (Moraceae) ...
Cordeiro, GláuciaCoordenação de Aperfeiçoamento de Pessoal de Nível Superior; Among the members of the subfamily Lamiinae are the twig girdlers that girdle branches and stems of trees. The larval stage is the longest in the life cycle of twig girdlers. In Minas Gerais State the species Oncideres saga (Dalman, 1823), Oncideres ocularis Thomson, 1868 and Oncideres ulcerosa (Germar, 1824) are commonly found. Few researches are con...
Aspectos biológicos de Oncideres saga (Dalman) (Coleoptera: Cerambycidae) e efe...
Cordeiro, GláuciaCoordenação de Aperfeiçoamento de Pessoal de Nível Superior; The present study was performed to obtain information on the biology of Oncideres saga (Dalman, 1823) and to evaluate the effects of its girdling of branches and trunks of Acacia mangium Willd. trees in terms of increase in diameter and height . The study on the biology of this insect pest was performed in a plantation of A. mangium located in Coimbra...
Occurrence of Oncideres dejeanii Thomson (Cerambycidae) in Pyrus pyrifolia (Ros...
Cordeiro, Gláucia; Anjos, Norivaldo; Lemes, Pedro Guilherme; Matrangolo, Carlos Augusto RodriguesThe twig girdler beetles are known for damaging many tree species. These beetles girdle branches and use them to lay their eggs and complete the offspring development. The objective of this work was to describe the occurrence of a case of O. dejeanii girdling Pyrus pyrifolia (pear tree) branches. Three girdled branches of P. pyrifolia were collected and on two of these were captured a female of this twig-girdle...
