Macuco bean (Pachyrhizus spp.) Is an atypical horticulture that has toxicity in its seeds and has potential for disease control, but its effect on soil stability is unknown? Among the bioindicators to evaluate soil quality is the analysis of fauna diversity, considered to be the most sensitive for presenting rapid response to changes. Therefore, the objective of this study was to determine the effect that macuco bean extracts and Cabrio® Top fungicide have on the soil mesofauna, with a completely randomized block design with three treatments and six replications. The treatments were: bean extract (1: 1000), a solution of Cabrio® Top (1: 250) and the water control. Pipes 100 mm in diameter were inserted into the soil 10 cm deep, one pipe being the experimental unit. For the extraction of mesofauna the Berlese-Tullgren method was used. After eight days in the extractor the samples with the mesofauna were removed for proper counting on the stereoscope. Moisture, group richness and abundance of individuals were evaluated. The results showed that soil moisture favored the richness of the edaphic mesofauna. Extract and Cabrio® Top compared to water increased the richness of faunal groups, but water presented higher abundance of specimens. However, all evaluated variables did not show significant variability between treatments. Therefore, Macuco bean extract and Cabrio® Top maintained soil quality without imbalancing the edaphic mesofauna.

El Niño intensifies the temperature increase in the Amazon region, causing heat and extreme drought in much of the Amazon, in Manaus the process of urbanization intensifies the temperature increase of the city. This study aims to perform an analysis of climatological variables of the city of Manaus-AM, from January 2008 to December 2018, through the maximum and minimum temperature, precipitation and relative humidity in order to show the increase in temperature through statistical analysis showing the temperature. year of greatest impact. According to the results obtained, in 2008 Manaus recorded the lowest minimum temperature in the period being 23.4 ° C, characterizing the minimum maximum temperature with 32 ° C, it is noted that due to the presence of the negative phase of ENSO ( La Niña) in 2008 the precipitation level in the region was high, contributing to the low temperatures and the relative air humidity averaged 87%, and the highest annual average of the maximum and minimum temperature in the study period occurred in 2015. , being 33.5 ° C and 25.7 ° C, due to the positive phase of ENSO (El Niño), temperatures in the capital were high, with little precipitation during the year directly impacting the relative humidity (75%). . Therefore, the positive / negative ENSO anomalies had a major influence on the climatic variables in the year 2008 and 2015, characterizing low temperatures in 2008 and high temperatures in 2015.
