Risco de dispersão de Anastrepha grandis (Macquart) (Diptera: Tephritidae), com ênfase na área livre da praga
Anastrepha grandis (Diptera: Tephritidae) é uma mosca-das-frutas que causa danos econômicos em cucurbitáceas, como melão e abóbora. A praga possui status de quarentenária em vários países, pois está restrita à América do Sul e é o principal fator limitante à exportação de cucurbitáceas brasileiras. …

The complex foraging strategy of the specialised gallfly Urophora cardui (Diptera: Tephritidae) for host plants (Cirsium arvense, Asteraceae)
Nearly all herbivorous insects in terrestrial ecosystems depend on plants for their survival and reproduction. They dominate terrestrial ecosystems due to species and individual abundance. Interactions between these two groups are thus of a high significance for the analysis and the understanding …

Discovery and Phylogeny of the Odorant Binding and Chemosensory Proteins of Diabrotica Virgifera Virgifera (Coleoptera: Chrysomelidae) and Rhagoletis (Diptera: Tephritidae)
Although great strides have been made, we still lack a complete understanding of the molecular aspects of insect olfaction. Such knowledge has applications in pest control, as well as being crucial to understanding specific olfactory pathways and their evolution. Evidence suggests that both …
