Abstract
En Oxapampa, diversas especies de la familia Chrysomelidae son consideradas plagas agrícolas, lo que, dado su potencial de afectación sobre los cultivos hortícolas, hace imprescindible su estudio. Ante ello, el objetivo de esta investigación fue identificar los crisomélidos asociados al agroecosistema hortícola del Campo Experimental Miraflores III de la Universidad Nacional Daniel Alcides Carrión. Para ello, se realizaron siete recorridos en el campo hortícola desde el 9 de mayo al 11 de julio de 2025. Se registró especies vegetales asociados a la familia Chrysomelidae y, además, se evaluó el índice de Simpson para estimar su diversidad. Se encontró cuatro taxones, predominando Epitrix (Alticini) (59.54%), seguida de Acalymma (Luperini) (26.78%), Diabrotica (Luperini) (11.56%) y Gynandrobrotica (Luperini) (2.12%), esta última reportada por primera vez en el distrito. El índice de diversidad fue de 0.56. En conclusión, la comunidad de Chrysomelidae asociada a cultivos hortícolas en el Campo Experimental Miraflores III (Oxapampa) estuvo conformada por cuatro taxones, los cuales se encontraron vinculados a 25 especies vegetales.
In Oxapampa, various species of the Chrysomelidae family are considered agricultural pests, which, given their potential impact on horticultural crops, makes their study essential. In this context, the objective of this research was to identify the chrysomelids associated with the horticultural agroecosystem of the Miraflores III Experimental Field at the Daniel Alcides Carrión National University. To this end, seven surveys were conducted in the horticultural field from May 9 to July 11, 2025. Plant species associated with the family Chrysomelidae were recorded, and the Simpson index was also evaluated to estimate their diversity. Four taxa were found, with the Epitrix (Alticini) being the most predominant (59.54%), followed by Acalymma (Luperini) (26.78%), Diabrotica (Luperini) (11.56%), and Gynandrobrotica (Luperini) (2.12%), the latter being reported for the first time in the district. The diversity index was 0.56. In conclusion, the Chrysomelidae community associated with horticultural crops in the Miraflores III Experimental Field (Oxapampa) consisted of four taxa, which were linked to 25 plant species.
