Fungal diseases may cause significant damage to crops worldwide, generating yield losses, poor grain quality, and health risks to humans and animals. Biological control using antagonistic bacteria offers innovative solutions for sustainable management aiming at plant protection. However, beneficial plant-microorganism interactions are particular, and few antagonists with broad-spectrum activity have been reported. In this work, two bacteria isolated from sorghum seeds were identified by partial sequencing of the 16S rRNA gene and tested in vitro for their capacity to control six important pathogenic fungi of maize: Fusarium verticillioides, Macrophomina phaseolina, Stenocarpella sp., Fusarium graminearum, Colletotrichum graminicola, and Bipolaris sp. The molecular identification revealed that the bacterial isolates belong to the genera Bacillus (strain LIS05) and Paenibacillus (strain LIS04). Both bacterial isolates inhibited the growth of all six phytopathogens by at least 49%. The isolate LIS05 showed the most significant antagonistic potential against the fungal pathogens tested, at an average of 73% inhibition. The highest antagonist activity (86.1% inhibition) was observed in the confrontation test between the isolate LIS05 and C. graminicola. In addition to the mycelial growth inhibition, the isolate LIS04 blocked the production of dark pigments by Bipolaris sp. This study showed that LIS05 and LIS04 are promising alternatives for developing integrated management strategies to control fungal diseases in maize and sorghum MenosFungal diseases may cause significant damage to crops worldwide, generating yield losses, poor grain quality, and health risks to humans and animals.

This is the first survey of Tephritidae and Lonchaeidae, their host plants and parasitoids in the state of Sergipe, Brazil. Fruits of several plant species were sampled in orchards, backyards, and farmers markets of 13 municipalities, from October 22 to 26, 2018 and from January 7 to 11, 2019. We collected 89 fruit samples (4,930 fruits, 111.5 kg) from 28 plant species belonging to 17 families. Larval infestation occurred in 29 fruit samples belonging to 11 plant species from eight families. We also used McPhail traps baited with Ceratrap®, in five municipalities. Five species of fruit flies (Anastrepha spp. and Ceratitis capitata), three species of lance flies (Neosilba spp.), nine of host plants, and associated parasitoids (1 species) were recorded for the first time in the state of Sergipe. |
