The diversity of arthropods present in the crops of yellow and whiteChrysanthemum morifolium Ramat. in greenhouse is analyzed, based on the speciesrichness, abundance and trophic roles. The study was carried out in a greenhouse located inEl Carmen (Jujuy). Field tasks consisted of three strokes per plant to 30 plants takenrandomly, with two repetitions, and a specific sampling of extraction of five flowers in threeopening states (floral bud, flower-semi-open and open flower) for each color throughout thecrop cycle. Samples were observed under a stereoscopic microscope for the extraction ofthe associated arthropods, which were identified and stored in flasks with 70% ethanol aswell as microscopy slides. A total of 9,027 arthropods were collected, distributed in theclasses Insecta (eight orders and 25 families) and Arachnida (three orders and nine families).The most diverse functional group was the phytophagous. This included the dominantspecies Frankliniella occidentalis (Thysanoptera) and Tetranychus urticae (Prostigmata). Theentomophagous group was represented by Anthocoridae (Hemiptera), Chrysopidae(Neuroptera) and 11 families of Hymenoptera parasitica, Phytoseiidae (Mesostigmata) andseven families of Araneae. The less abundant groups were the detritivores (Psocoptera),fungivores (Latridiidae), xylophagous (Bostrichidae), and the varied diet (Formicidae)
