Diversidade da entomofauna edáfica no "Sítio Brotando a Emancipação/Cascavel-CE”, em diferentes coberturas vegetais e períodos sazonais

Abstract

Soil fauna is responsible for numerous processes that interfere with soil dynamics and, together with chemical and physical factors, influence soil/plant interaction. In addition, the fauna of the soil is also an ecological bioindicator, revealing possible impacts caused by external factors such as pollution, cultural practices and forms of cultivation. The objective of this study was to quantify the composition and distribution of edaphic entomofauna present in areas with different vegetation cover in different seasonal periods, in order to evaluate the influence of the practices adopted by the project in the soil insect community. The experiment was carried out in the site "Sprouting the Emancipation", located in the municipality of Cascavel-CE, using areas with approximately 100 m2 each, being: One with macaxeira (monoculture) cultivation; another with intercropping with maize, beans, cassava and watermelon (polyculture); another with a newly implemented system of SAF (Agroforestry System) and a native forest area (control). Five Pitfall traps were distributed in each area in two distinct periods (rainy and dry) being arranged 8 m apart. After the collection, the captured organisms were screened, with the aid of a stereoscopic microscope at the Laboratory of Applied Entomology of the UFC. Regarding diversity, none of the areas differed from the control and, in general, there were few changes caused by soil management systems, demonstrating that the practices adopted by the project did not negatively affect soil arthropods.
