Ocurrencia de Ceresa nigripectus (Hemiptera: Membracidae) en vides de la región cuyana de Argentina

En la provincia de Mendoza se han observado ninfas y adultos de una chicharra, que al alimentarse de los órganos de la vid (Vitis vinifera L.) causa lesiones y sintomatologías producto de la respuesta de la planta. Dada su similitud con otras afecciones, el cuadro sintomatológico muchas veces no es reconocido por los viticultores. En esta contribución se da a conocer a C. nigripectus como el membrácido que afecta los viñedos mendocinos y se destaca su importancia por ser una especie nativa ampliamente distribuida en el país, que ha demostrado tener capacidad infestiva en alfalfares y ser potencial vector del fitoplasma ArAWB, agente causal de la “escoba de bruja de la alfalfa”. Asimismo, se marcan los rasgos diagnósticos más relevantes y se caracterizan las lesiones y sintomatologías observadas en la vid producto de la alimentación del insecto, para que sean fácilmente reconocidas a campo.In Mendoza province, which belongs to Argentina ‛Cuyo’ region, has been seen treehopper nymphs and adults, which feed leaves, branches and clusters of the vine causing a symptomatology product of the plant’s response. The symptoms are not often recognized by the winegrowers due to the similarity to other grapevine disorders. In this contribution C. nigripectus is identified as the Membracidae that causes injuries in vineyards and its importance is highlighted because it is a common native species in alfalfa crop and potential vector of ArAWB phytoplasma causing “alfalfa witches broom”. Also are provided the most relevant diagnostic features and symptoms occurred in the vineyard to be easily recognized in the field.Gerencia de Comunicación Institucional, DG SICyP, INTAFil: Vicchi, Franco R.

Inventory of some families of Hemiptera, Coleoptera (Curculionidae) and Hymenoptera associated with horticultural production of the Alto Valle de Río Negro and Neuquén provinces (Argentina)

The knowledge of the entomological fauna in productive systems is important for the agroecological management since beneficial insects are a key resource for pest management in horticultural systems. Scientific information on the biodiversity present in a given area is essential as well as the ecological function and/or feeding habits of the insects. In Alto Valle de Río Negro and Neuquén, horticultural production systems can be described as highly dependent on chemical inputs for pest management and fertilization. The aim of this study is to carry out an inventory of the biodiversity of some families of Hemiptera, Coleoptera (Curculionidae) and Hymenoptera present in peri-urban and rural farms located in Neuquén and Río Negro, respectively. Insects were collected through pitfall and sweeping net on tomato and pepper crops and the surrounding non-cultivated areas. Idiosystatus Berg (Auchenorrhyncha) was cited for the first time from Argentina. Species cited for the first time from Neuquén: Hemiptera: Auchenorrhyncha: Acanalonia chloris (Berg), Syncharina punctatissima (Signoret), Amplicephalus dubius Linnavuori, Exitianus obscurinervis (Stål), Agalliana ensigera Oman and Bergallia signata (Stål); Hemiptera: Heteroptera: Harmostes (Harmostes) prolixus Stål and Atrachelus (Atrachelus) cinereus (Fabricius); Coleoptera: Curculionidae: Hypurus bertrandi (Perris), Naupactus leucoloma Boheman, Otiorhynchus rugosostriatus (Goeze) and Sitona discoideus Gyllenhal and Hymenoptera: Xylocopa (Neoxylocopa) augusti Lepeletier and Pseudagapostemon (Neagapostemon) singularis Jörgensen. Species cited for the first time from Río Negro: Hemiptera: Auchenorrhyncha: Amplicephalus dubius Linnavuori, Amplicephalus marginellanus Linnavuori, Circulifer tenellus (Baker) and Xerophloea viridis (Fabricius); Hemiptera: Heteroptera: Tupiocoris cucurbitaceus (Spinola), Atrachelus (Atrachelus) cinereus (Fabricius), Dichelops furcatus (Fabricius) and Harmostes (Harmostes) prolixus Stål; Coleptera: Curculionidae: Naupactus xanthographus (Germar) and Hymenoptera: Diadasia pereyrae (Holmberg) and Dialictus autranellus (Vachal).El conocimiento de la fauna entomológica presente en los sistemas productivos es importante para el manejo agroecológico ya que los insectos beneficiosos son un recurso clave para el manejo de plagas en los sistemas hortícolas.
