SUMMARY:

In general, knowledge regarding the diversity of insects in agroecosystems is associated with phytophagous organisms, which, in large populations (due to ecological imbalances), become harmful and, therefore, more perceptible to humans, from the farmer to society consumer of agricultural products. However, with the increase in demand for agricultural products whose cultivations respect the aspects of sustainability, the biological control agents of these phytophagous organisms are gaining more visibility or even popularity, although still focusing on exotic species, particularly entomophagous insects. However, it is the popularization of native species of biological control agents and their ecology that will favor their conservation and contribute to regional advances in landscape management strategies. Having access to information about such organisms becomes essential in the search for sustainable production systems. The transition to agroecological-based production systems, including organic agriculture, depends on techniques and processes that conserve and increase the functionality of biodiversity, in order to make agroecosystems more resilient and profitable. The importance given to this biodiversity varies with the degree of perception of the observer, whom be agriculturalists, farmers, extension workers or laypeople. The present proposal starts from the perception that the presence of Cratylia argentea, a perennial legume native to Brazil, is capable of supporting the survey of the diversity of these beneficial insects and their popularization. The fact that it remains leafy throughout the year creates microclimates favorable to the protection and multiplication of biodiversity, which may favor the dispersion of many of these organisms to the cultivated areas during the rainy season. With biweekly observations of cratília plants in two municipalities of Minas Gerais (Sete Lagoas and Fortuna de Minas), a photographic record of organisms visiting their flowers will be made, which will allow the elaboration of tools (booklets, environmental photography magazine and online websites) of popularization of biological control agents and bees in the central region of Minas Gerais. The presence of the legume and the associated biodiversity, in a given location and time, may offer evidence of environmental quality or levels of degradation in the region. The photographic catalog of visiting bees and biological control agents recorded during the flowering period of C. argentea (which occurs in the central region of Minas Gerais during the dry period of the year) aims to popularize these organisms for farmers, technicians, researchers and the general public in an agile way. It is intended to demonstrate that this legume must provide shelter, food, prey and/or hosts for the surrounding entomofauna, in order to contribute to natural biological control and pollination, increasing the balance of local agroecosystems. Commonly, several beneficial insects are eliminated from the productive fields by the farmer for not knowing them and/or not knowing their ecological importance in the balance of productive agroecosystems. In this way, the on-site recognition of the insect will allow to subsidize actions that guarantee and promote the conservation of beneficial biodiversity in the place. The material generated with this study proposal may also support the planning of landscapes in productive systems in agroecological transition. The availability of photographic records in digital form will allow people to access material with information on the ecology of visiting organisms, as long as there is a cell phone, tablet or computer and a good internet network. The methodology used can be improved in different contexts, it will support similar surveys in different regions where the plant is established. The digital photographic record represents a technical product of great practicality in helping farmers, technicians, researchers, and the general public in the rapid identification of insects at the field level, providing knowledge/recognition of living beings of interest productive agroecosystems. Emater-MG, Embrapa (Corn and Sorghum and Agrobiology) and UFRRJ share an interest in the search for sustainable production systems. Emater-MG focuses on family farm (agricultura familiar) and sustainable production, constantly interacting with Embrapa with the intention of identifying techniques and processes consistent with the reality and demands of its target audience. Embrapa and UFRRJ have networks of collaborating researchers and university professors who can support the identification and ecology of registered organisms.
