Título: First report of Crematogaster acuta (Fabricius, 1804) (Hymenoptera: Formicidae) in association with palm-aphid on solitary açaí palm seedlings (Euterpe precatoria Martius) in Acre, Brazil. Autoria: BONA, K.; SANTOS, R. S.; FONTENELE, L. K.; SOUZA, K. M. de; FEITOSA, R. M. Conteúdo: Ant-hemipteran mutualisms are widespread in tropical ecosystems yet remain undocumented in many Amazonian plant species. Here, we report the first record of a trophobiotic association between the acrobat ant Crematogaster acuta (Fabricius, 1804) and the palmaphid Cerataphis brasiliensis (Hempel, 1901) on seedlings of Euterpe precatoria Martius, 1842 (Arecaceae) in the state of Acre, Brazil. Ants were observed tending aphid colonies, collecting honeydew, and exhibiting protective behaviors against potential predators. This novel record adds to the growing knowledge of ant-aphid interactions in Amazonian palms and suggests potential ecological implications for aphid persistence and solitary açaí palm seedling health.

Título: First record of Cadra cautella (Walker, 1853) (Lepidoptera: Pyralidae) infesting Brazil nut (Bertholletia excelsa) in Nova Califórnia, Rondônia, Brazil. Autoria: SANTOS, R. S.; CARTAXO, C. B. da C.; MELO, A. L. de Conteúdo: The Brazil nut tree (Bertholletia excelsa Humboldt & Bonpland, Lecythidaceae) is a heliophytic species native to the Amazon region. The present study aims to document the presence of a lepidopteran borer infesting Brazil nuts in the state of Rondônia, located in the southwestern region of the Brazilian Amazon.

Título: Primeiros registros de Herminodes sp. (Lepidoptera: Noctuidae) em açaizeiros nos estados do Amapá e Amazonas, Brasil. Autoria: SANTOS, R. S.; MELEM JUNIOR, N. J.; LIMA, A. L.; ACIOLI, A. N. S.; SILVA, N. M. da; ADAIME, R. Conteúdo: Conhecer as espécies de insetos que ocorrem em cada região, seus hábitos e biologia, é fundamental para evitar perdas agrícolas. Neste contexto, este trabalho tem o objetivo de relatar a ocorrência e os danos do ataque de lagartas de Herminodes sp. (Lepidoptera: Noctuidae) em cultivos de açaizeiro-solteiro e açaizeiro-de-touceira nos estados do Amapá e Amazonas.

Título: First record of tetranychidae (Acari: Tetranychidae) on Euterpe precatoria (Arecaceae) in the Brazilian Amazon. Autoria: VASCONCELOS, J. G. N. de; SANTOS, R. S.; FERLA, N. J. Conteúdo: The Arecaceae family comprises a diverse group of species ranging from small shrubs to large trees, commonly known as palms. Knowledge on the insects and mites associated with this palm is essential for providing sound management recommendations for the primary pest organisms present. Among the primary pest mites in cultivated plants are those belonging to the Tetranychidae family, which includes the most important pest mite species in agriculture, whose population outbreaks can lead to severe losses and even plant death.
