SUMMARY:

In addition to the production of food, fiber and/or energy and the generation of work and income, the designs of agroecologically based agroecosystems, including organic agriculture, depend on practices that conserve and enhance the functionalities of biodiversity, in order to make them more resilient and profitable. Therefore, the plant diversity that makes up an agroecological production system must include plants that reactivate or optimize ecosystem services, stimulating the biological components that exert, for example, biological nitrogen fixation, pollination and biological control. Cratylia argentea (Desvaux) O. Kuntze (Fabaceae), popularly known as cratilia, is a perennial, pollen-bearing, nectary-bearing species, native to the Brazilian Cerrado, and with multiple agricultural uses (e.g., green manure, forage and area recovery). degraded). This work aimed to know the beneficial arthropod fauna associated with cratilia during its full bloom in the central region of Minas Gerais, using digital photography to reveal its potential in the conservation of these organisms. The study was conducted during the cratilia flowering period from April to August 2020 and April to July 2021. Photographic records of beneficial arthropods were made using Canon EOS T5 and T6 digital cameras, observing cratilia plants grown in the Fazenda da Mata in the municipality of Fortuna de Minas/MG, on a private site in the rural community of Fazenda Velha and at Embrapa Milho e Sorgo (Bosque dos Empregados), both in the municipality of Sete Lagoas/MG. Observations were made every 14 days, between 9:00 am and 11:00 am and 1:00 pm and 3:00 pm, alternating periods between sites. In 2020 and 2021, in addition to the exotic bee Apis mellifera L. (Hymenoptera: Apidae), the native bees of the same family photographed were those of the genera Centris Fabricius, Plebeia Schwarz, Tetragona Lepeletier & Serville, Tetragonisca Latreille, Trigona Jurine and Xylocopa Latreille. The bee images also revealed the presence of the genera Megachile Latreille (Hymenoptera: Megachilidae) and Oxaea Klug (Hymenoptera: Andrenidae). Spiders (Arachnida: Araneae) and entomophagous insects of different orders were also photographed. Among insects with a predatory life stage, adult ladybirds (Coleoptera: Coccinellidae), lacewings (Neuroptera: Chrysopidae), flower flies (Diptera: Syrphidae), praying mantis (Mantodea: Mantidae) and bed bugs (Hemiptera: Reduviidae). Adult parasitoids were also photographed, such as wasps Braconidae and Ichneumonidae (Hymenoptera) and parasitic flies from the family Tachinidae (Diptera). Wasps (Hymenoptera: Vespidae) were also recorded, some being predators and others possible pollinators. It is concluded that several beneficial arthropods visit the flowers and other parts of the cratilia, in order to represent a place of shelter and food source during its full bloom. These results indicate that cratilia has potential for use as an on-farm conservation strategy for beneficial arthropods, especially pollinating insects (mainly bees) of agriculturally important plant species, and predatory and parasitic arthropods, many of which are considered important biological control agents of agricultural pests.
