Resumo: Leafcutter ants are considered pests in agriculture for their impact in human crops, as they behave utilizing foliar fragments to raise their simbiont fungi (Agaricales: Lepiotaceae) inside their nest. Recent studies have noticed that other fungi may be associated to ants inside their nests, for instance, fungi with melanized wall, known by “dematiaceous”. Historically, many black fungi have been noticed as fitopathogens of many plant cultures with economic importance, highlighting dematiaceous ecological behavior importance in this study. This investigation had the purpose of amplifying ecological knowledge of this fungi, isolating and identificating dematiaceous fungi found in Attini nests, having the intention of understanding plant pathogens dispersion by ants. In this work, 66 isolates were characterized in the following genus: Aspergillus, Penicillium, Paecilomyces, Oxyporus, Rhodotorula, Bipolaris, Curvularia, Fusarium, Giberella, Paraphaeosphaeria, and Cladosporium. The genus Bipolaris, Curvularia, Fusarium and Giberella are known for their opportunistic behaviour, with some published human infections in literature. Fusarium is a notorious fitopathogen, with wide number of descriptions and studies involving pathogenicity development, biochemistry and genetics. The isolates outline is of phyto – associated (phytopathogens, endophytic or epiphitic), fulfilling this work intention in alarming fungi capacity of dispersal by ants. The comprehension of phytopathogenical processes may be clarified based on the knowledge of oportunistics fungi that may utilize ants bodies for their own dispersal. The identification of isolates with capacity of infecting humans brings out public health issues.

Estudos recentes observaram que, além do simbionte, outros fungos podem estar associados aos ninhos das formigas, como por exemplo, os que apresentam melanina na parede celular, conhecidos como dematiáceos. Historicamente, várias espécies de fungos negros encontram-se relacionados a doenças de plantas, muitas de importância econômica, por isso a alta relevância do estudo destes grupos. Esta investigação objetivou ampliar o conhecimento sobre a ocorrência destes fungos em formigas Attini. Aplicou-se técnicas de cultivo seletivas a fim de se isolar fungos negros (dematiáceos) de ocorrência em ninhos de formigas Atta laevigata e A. sexdens rubropilosa, na premissa de compreender a capacidade dispersora das formigas para com os fungos negros. No trabalho aqui apresentado foram identificados 66 estripes pertencentes aos seguintes gêneros: Aspergillus, Penicillium, Paecilomyces, Oxyporus, Rhodotorula, Bipolaris, Curvularia, Fusarium, Giberella, Paraphaeosphaeria, e Cladosporium. Os gêneros Bipolaris, Curvularia, Fusarium e Giberella são típicos fungos oportunistas, causando infecções até mesmo em seres humanos, conforme dados na literatura. O gênero Fusarium é excepcional fitopatógeno, com ampla descrição e estudos com relação à sua bioquímica e genética. O perfil dos isolados é de fito–associados (fito–patogênicos, endofíticos ou epifíticos), cumprindo uma das premissas deste trabalho em alertar sobre e caracterizar a capacidade dispersora das formigas. A compreensão de processos fito – patogênicos pode ser esclarecida à partir da caracterização de fungos oportunistas que se utilizam de insetos, em contato com o solo, para se dispersarem...(Resumo completo, clicar acesso eletrônico abaixo)Universidade Estadual Paulista (Unesp)Angelis, Derlene Attili de [UNESP]Pagnocca, Fernando Carlos [UNESP]Universidade Estadual Paulista (Unesp)Guedes, Fábio Lúcio Antunes [UNESP]2015-03-23T15:18:52Z2015-03-23T15:18:52Z2010info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/bachelorThesis83 f.application/pdfGUEDES, Fábio Lúcio Antunes.
