Abstract
El objetivo del presente estudio fue determinar los artrópodos asociados a las flores del cultivo de chirimoyo (Annona cherimola), ubicado en el distrito de Callahuanca en la provincia de Huarochirí en Lima, Perú. Se realizaron colectas directamente de las flores durante la antesis, desde el 04 de enero hasta el 22 de febrero de 2020. Se eligieron de manera aleatoria 40 árboles, de los cuales se evaluaron cinco semanalmente, abarcando un período total de ocho semanas de evaluación. Para llevar a cabo este procedimiento, se establecieron puntos de colectas ubicados en los hemisferios norte y sur de cada árbol. Se consideraron los estratos superior e inferior, así como la ubicación interna y externa de las flores en la copa de los árboles. Además, se tuvieron en cuenta las fases femenina y masculina de las flores del cultivo. Posteriormente, los especímenes colectados fueron procesados en el Museo de Entomología Klaus Raven Büller en la Universidad Nacional Agraria La Molina, donde se realizó la clasificación taxonómica de cada morfotipo empleando claves taxonómicas, con el respaldo adicional de especialistas para garantizar la precisión en el proceso de identificación. Se registraron artrópodos de las clases Arachnida, Collembola e Insecta, siendo esta última la más predominante con 20 morfoespecies y 240 individuos. La especie más numerosa fue Neohydatothrips burungae, perteneciente a la familia Thripidae, con un total de 155 individuos. En segundo lugar, se encontró la especie Entomobrya sp. de la familia Entomobryidae, con 53 individuos, seguida por Rhinacloa sp. de la familia Miridae, con 33 individuos. Estos resultados contribuyen con el conocimiento de la diversidad de artrópodos presentes en las flores del chirimoyo, destacando la importancia de las investigaciones entomológicas para gestionar la biodiversidad en esta zona de estudio.
The aim of this study was to determine the arthropods associated with the flowers of the cherimoya crop (Annona cherimola), located in the district of Callahuanca in the province of Huarochirí in Lima, Peru. Collections were made directly from the flowers during anthesis, from January 04 to February 22, 2020. Randomly selected 40 trees, of which five were evaluated weekly, covering a total period of eight weeks of evaluation. To perform this procedure, collection points were established in the northern and southern hemispheres of each tree. The upper and lower strata were considered, as well as the internal and external location of the flowers in the canopy of the trees. In addition, the female and male phases of the crop flowers were taken into account. Subsequently, the collected specimens were processed at the Klaus Raven Büller Entomology Museum at the Universidad Nacional Agraria La Molina, where the taxonomic classification of each morphotype was carried out using taxonomic keys, with the additional support of specialists to ensure accuracy in the identification process. Arthropods of the classes Arachnida, Collembola and Insecta were recorded, the latter being the most predominant with 20 morphospecies and 240 individuals. The most numerous species was Neohydatothrips burungae, belonging to the family Thripidae, with a total of 155 individuals. In second rank was Entomobrya sp. of the Entomobryidae family, with 53 individuals, followed by Rhinacloa sp. of the Miridae family, with 33 individuals. These results contribute to the knowledge of the diversity of arthropods present in cherimoya flowers, highlighting the importance of entomological research to manage biodiversity in this study area.
