This inventory provides a comprehensive list of 286 agriculturally important insect species from cruciferous crops (bok choy, broccoli, brussels sprouts, cabbage, cauliflower, kale, mustard, radish, rapeseed, and toria), spanning 10 orders: Coleoptera, Dermaptera, Diptera, Hemiptera, Hymenoptera, Lepidoptera, Neuroptera, Odonata, Orthoptera, and Thysanoptera. These species belong to 53 families, with Coccinellidae comprising the most species (39), followed by Syrphidae (22) and Apidae (20). Functional diversity analysis highlights that foliage feeders dominate the pest category (52%), while nymphaladult predators make up the majority of natural enemies (45%). Larval parasitoids and pupal parasitoids account for 27% and 10%, respectively. Hymenoptera (51%) leads among pollinators, followed by Lepidoptera (21%) and Diptera (17%). This first-of-its-kind inventory serves as a valuable resource for field entomologists and other stakeholders in pest management and conservation strategies.
