arthropods, significant biodiversity, peas.
In 2023, 10 arthropod harvests were carried out in the pea crop, collecting 77 taxa and 1962 specimens. The most abundant species were Dermestes laniarius (277 specimens), ants (274 specimens) and Coccinella septempunctata (265 specimens). The largest harvest was achieved at the first harvest, with 447 specimens, dominated by Coccinella septempunctata (128 specimens). Regarding the classes, Insecta was the best represented, with 1801 specimens (91.79%), followed by Arachnida (157 specimens, 8%) and Diplopoda (4 specimens, 0.2%). The insect orders included Coleoptera (1109 specimens), Hymenoptera (365), Orthoptera (117), Lepidoptera (80), Heteroptera (74), Diptera (55) and Neuroptera (1). Among arachnids, Opiliones (152) and Acari (7) were encountered, and among diplopods only the order Julida (4) was encountered. In 2024, 6 harvests were carried out, collecting 70 taxa and 2041 specimens. The largest groups were Diptera (447 specimens), Coccinella septempunctata (268) and Opatrum sabulosum (176). The richest harvest was the first, with 575 specimens, dominated by Opatrum sabulosum (172). The classes had a similar distribution to the previous year: Insecta (1865 specimens, 91.38%), Arachnida (169, 8.28%) and Diplopoda (7, 0.34%). The collected insect orders were Coleoptera (1039 specimens), Hymenoptera (180), Orthoptera (143), Lepidoptera (4), Heteroptera (48), Diptera (447) and Homoptera (2). Among arachnids, Opiliones (162) and Acari (7) were identified, and among diplopods, Julida (7 specimens). Thus, both seasons demonstrated a significant biodiversity, with the predominance of insects, especially Coleoptera and Diptera, highlighting the ecological structure of the pea agroecosystem.
