“…El proceso agro-productivo de la berenjena para cumplir con su ciclo completo desde la preparación del terreno hasta la recolecta de las diferentes cosechas acuerdo a lo manifestado por los propios agricultores en el departamento durante las visitas de campo y elaboración de las encuestas, deben estar supervisado y controlado permanentemente de plagas que comúnmente se presentan como son: las mosquitas, ácaros, gusanos, grillos, morrocollita y otros, por lo cual se deben controlar y/o erradicar con el uso de insecticidas y plaguicidas, como se determina en las investigaciones de Camacho (2017); Salas Gervassio (2017); Garrido et al (2017); Barraza et al (2017); y Lugo et al (2018).…”

El articulo pretende determinar los impactos socio-económicos en las familias productoras de la berenjena en el departamento del Atlántico, a través de un estudio en el proceso agro productivo, los resultados son objeto de análisis y socialización ante actores interesados, como, agricultores, empresarios, distribuidores; la investigación se fundamenta en analizar una realidad objetiva a partir de mediciones numéricas y análisis estadísticos para determinar predicciones o patrones de comportamiento del fenómeno o problema planteado; con un tipo de investigación descriptiva con diseño no experimental y de campo; la información se recolecto con una encuesta mediante el uso de un cuestionario, la población objeto de estudio son las familias agricultoras, el tamaño de la muestra se tomó basándose en la fórmula para población finita que determino 132 cultivadores de 7 de los 23 municipios que conforman el departamento como son: Sabanagrande, Malambo, Baranoa, Polonuevo, Candelaria, Palmar de Varela y Ponedera. Para lograr producir 1 tonelada de berenjena en el departamento del Atlántico por parte de los agricultores tradicionales, se debe invertir $107.633 x tonelada, multiplicado con el rendimiento o producción de 28 toneladas producidas en 7 meses, da como resultado los costos totales de producción $ 3.013.720. Se concluye, que por cada $1 pagado por el consumidor, $0,7857 son ganancias para el vendedor final, es decir que al productor primario o agricultor, le corresponde de ese $1 pagado por el consumidor final, solo el $0,2143; demostrándose que el que más gana en esta cadena es el intermediario (valores año 2021)

“…The scientific knowledge of the insect fauna of the Alto Valle de Río Negro and Neuquén is scarce and strongly associated with pome fruit production for export markets, as illustrated by the following contributions: Hymenoptera (Dapoto & Giganti, 1994;Aquino et al, 2013;Garrido et al, 2017), Hemiptera: Sternorrhyncha (Giganti et al, 2004;Vera et al, 2012), Hemiptera: Auchenorrhyncha (Catalano et al, 2009;Paradell & Dellapé, 2015;D'Hervé et al, 2017); Lepidoptera (Garrido et al, 2007;Dapoto et al, 2010); Neuroptera (Gonzalez et al, 2011), Diptera (Santadino et al, 2015) and Coleoptera (Curculionidae) (del Río et al, 2019).…”

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)

“…Control methods for codling moth have mainly been based on the use of broad-spectrum insecticides and, to a lesser extent, more environmentally friendly tools, such as Mating Disruption Technique (Senasa, 2023) and the use of different exotic and native parasitoids (Garrido et al, 2005;Tortosa et al, 2014). Regarding G. legneri as a parasitoid of C. pomonella, Laumann et al (2000a) found a high survival rate, the predominance of females in the offspring and high fecundity, among other characteristics.…”

The functional and numerical response and the potential for mutual interference are key components in the selection of parasitoids for biological control. In this study, functional and numerical responses of Goniozus legneri to different densities of fifth instar Cydia pomonella larvae and mutual interference of this parasitoid were studied under laboratory conditions. Logistic regression was used to find the type of functional response and the result was type II. The attack rate, handling time, the parasitoid searching efficiency and the maximum host mortality rate were estimated by fitting the Holling model to the data. The numerical response of the parasitoid did not vary based on the availability of codling moth larvae. The negative value of the interference coefficient (−0.228) in the mutual interference analysis showed an inverse relationship between parasitoid density and per capita searching efficiency. This suggests that when the density of G. legneri and C. pomonella larvae is equivalent, the parasitoid proves to be more effective in pest control. The findings of this study contribute to increasing the knowledge of G. legneri and its potential as a biocontrol agent.
