Abstract Bees are important pollinators whose population has declined due to several factors, including infections by parasites and pathogens. Resource sharing may play a role in the dispersal dynamics of pathogens among bees. This study evaluated the occurrence of viruses (DWV, BQCV, ABPV, IAPV, KBV, and CBPV) and microsporidia (Nosema ceranae and Nosema apis) that infect Apis mellifera, as well as pesticide residues in the stingless bees Nannotrigona testaceicornis, Tetragonisca angustula, and Tetragona elongata sharing the same foraging area with A. mellifera. Stingless bees were obtained from 10 nests (two of N. testaceicornis, five of T. angustula, and three of T. elongata) which were kept in the field for 1 year and analyzed for the occurrence of pathogens. Spores of N. ceranae were detected in stingless bees but were not found in their midgut, which indicates that these bees are not affected, but may be vectors of the microsporidium. Viruses were found in 23.4% of stingless bees samples. APBV was the most prevalent virus (10.8%) followed by DWV and BQCV (both in 5.1% of samples). We detected glyphosate and its metabolites in small amounts in all samples. The highest occurrence of N. ceranae spores and viruses was found in autumn-winter and may be related to both the higher frequency of bee defecation into the colony and the low food resources available in the field, which increases the sharing of plant species among the stingless bees and honey bees. This study shows the simultaneous occurrence of viruses and spores of the microsporidium N. ceranae in asymptomatic stingless bees, which suggest that these bees may be vectors of pathogens.

Stenocarpella spp. causes stalk and ear rot in maize and overwinters in stubble during the off-season. Understanding the factors that guide saprophytic colonization is a crucial strategy for management. In this study, we analyzed the abiotic factors and crop management practices in relation to the inoculum of Stenocarpella spp. in stubble by qPCR. Soil samples were used for suppressiveness tests against Fusarium verticillioides, Fusarium graminearum, and Stenocarpella maydis. In the 29 fields, different levels of Stenocarpella spp. were detected. Only three fields were considered suppressive for the three pathogens. Heat maps showed that soil suppressiveness was inversely related to the pathogen concentration, and the suppressiveness of one pathogen was correlated with the suppressiveness of other pathogens. Under no-tillage systems in which rotation with soybeans was adopted, Stenocarpella spp. were detected at lower concentrations than in areas that adopted notillage systems with maize monocultures. While in tillage systems, the maize?maize monocropping increases the inoculum level of Stenocarpella spp. Crop rotation is a factor related to the observed reduction in the pathogen concentration and increases in the broad-spectrum antagonistic microbial communities. These communities guide the suppressiveness of soil-borne diseases in maize fields cultivated under tropical conditions. |
