CARACTERIZAÇÃO MICROBIANA DE CUPINS, CUPINZEIROS E SEU ENTORNO

Abstract

Termites are social insects that interfere with soil conditions through excavation and construction. The soil structure is made up of mineral particles, organic matter and the porous space between the particles, enabling the development of life forms. This study was carried out between September 2018 and November 2019, in the facilities of Campus Ceres of the Federal Institute of Goiano. The study points analyzed were defined disregarding the identification of species or grape varieties, aiming at the presence of active colonies. The treatments were: surrounding soil, mound soil and termite. In a completely randomized design, each sample collected was approximately 1g (gram) collections in a rainy season and a drought period. Samples were placed in sterile microtubules (Eppeendorf) and sent to the institution's microbiology laboratory. They were inserted into test tubes containing saline solution (85%). The isolates were pealed, grouped by morphotype. Microculture was started for identification at gender level. Obtaining the data, the exploratory analysis was performed to verify the assumptions of normality and homoscedasticity in software R, by Shapiro Wilk and Cochran. Quantified colony values were compared by the Kruskall-wallis (treatments) and Wilcoxon (period) tests. When comparing origins within each period, there is no statistical difference regarding growth in origins (P> 0.05). Analyzing the origins within the rainy season, there is a difference regarding the growth in the surrounding soil with the other origins. Eight fungal genera were identified at the end.
