ABSTRACT. The knowledge of the entomological fauna in productive systems is importantfor the agroecological management since beneficial insects are a key resource for pestmanagement in horticultural systems. Scientific information on the biodiversity present in agiven 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 describedas highly dependent on chemical inputs for pest management and fertilization. The aim ofthis 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 locatedin Neuquén and Río Negro, respectively. Insects were collected through pitfall and sweepingnet on tomato and pepper crops and the surrounding non-cultivated areas. IdiosystatusBerg (Auchenorrhyncha) was cited for the first time from Argentina. Species cited for thefirst time from Neuquén: Hemiptera: Auchenorrhyncha: Acanalonia chloris (Berg), Syncharinapunctatissima (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, Otiorhynchusrugosostriatus (Goeze) and Sitona discoideus Gyllenhal and Hymenoptera: Xylocopa(Neoxylocopa) augusti Lepeletier and Pseudagapostemon (Neagapostemon) singularisJörgensen. 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) andHarmostes (Harmostes) prolixus Stål; Coleptera: Curculionidae: Naupactus xanthographus(Germar) and Hymenoptera: Diadasia pereyrae (Holmberg) and Dialictus autranellus(Vachal).KEYWORDS. Beneficial insects. Pests. Surrounding vegetation. Tomato and pepper crops.
