Resumo: | The leaf-cutting ants are considered pests in the Brazilian economy because they cause big losses in the agricultural and forestry systems. Annually, large sums are spent seeking their control, which is done primarily through available insecticides. Their use is under heavy pressure of national and international certification due to the need to protect the environment because the current active ingredients available in the commercial insecticide formulations are not considered safe to the environment. The behavioral repertoire displayed by the ants is responsible for the difficulty in achieving ant control. Among the main behaviors performed by worker ants there are the autogrooming , allogrooming , trophallaxis and waste handling, which are responsible for maintaining the colony hygiene keeping it free of parasites and pathogens. The insecticide fipronil cause neural effects leading the individuals to death by hyperactivity, impairing key behavioral traits important for the colony maintenance. In this work, the workers were expose to fipronil by two ways: spraying and toxic baits. In the first, fipronil was sprayed in the soil where six colonies of Acromyrmex subterraneus subterraneus were placed. In the second, three grams of toxic bait were offered to five colonies to A. subterraneus subterraneus. The frequency of occurrence of the main behaviors was recorded. Under insect sprayed in soil, ant behaviors like autogrooming , disposal of adults and waste handling were reduced in colonies. Under toxic bait exposure, the ant behaviors of autogrooming , allogrooming , waste removal, and activities undertaken within the fungus garden by the minors workers were reduced resulting in the development of parasitc fungus Escovopsis present in the fungus garden of the colonies. Thus the two forms of the insecticide application have effects on workers of A. subterraneus subterraneus, however the baits have a more pronounced effect in the colonies and colony suppressed was achieved by affecting mainly minor workers. Since these workers are responsible for maintaining the symbiotic fungus, its absence culminates in the decay and death of the fungus garden and subsequent death of workers due to lack of food substrate, occurring, finally the complete suppression of colony. |

Anualmente grandes somas são gastas buscando seu controle, que é feito principalmente através de produtos sintéticos disponíveis no mercado. Alguns deles encontram-se sob forte pressão das certificadoras nacionais e internacionais devido à necessidade de proteção dos ecossistemas, pois seus princípios ativos não são considerados adequados ao ambiente. O repertório comportamental apresentado pelas formigas é um dos responsáveis pela dificuldade encontrada em seu controle. Entre os principais comportamentos executados pelas formigas operárias encontra-se o autogrooming , allogrooming , trofalaxia e manipulação do lixo que são responsáveis pela manutenção da higiene da colônia, mantendo-a fora da ação de parasitas e patógenos. O inseticida fipronil é causador de efeitos no sistema nervoso podendo comprometer os indivíduos expostos e suprimir a colônia. Neste trabalho as operárias entraram em contato com o inseticida fipronil por duas vias: pulverização de solução de fipronil e iscas formicidas. No primeiro, aspergiu-se uma concentração subletal do inseticida fipronil no solo onde foram colocadas seis colônias de Acromyrmex subterraneus subterraneus. No segundo três gramas de iscas formicidas foram oferecidas a cinco colônias de A. subterraneus subterraneus. Os principais comportamentos executados foram medidos através da frequência de acontecimento. Os comportamentos de autogrooming , descarte de adultos e a manipulação do lixo foram menores em colônias tratadas com o inseticida do que nas colônias testemunhas quando o inseticida foi pulverizado. Já com as iscas, os comportamentos de autogrooming , allogrooming , remoção de lixo, e atividades realizadas dentro do jardim de fungo pelas jardineiras foram reduzidos o que propiciou o aumento no desenvolvimento do fungo parasita Escovopsis presente no jardim de fungo das colônias. Assim, as duas formas de aplicação do inseticida possuem efeitos nas operárias de A. subterraneus subterraneus, no entanto, as iscas possuem um efeito mais pronunciado nas colônias e operárias dessa espécie e foram letais às operárias jardineiras. Uma vez que essas operárias são responsáveis pela manutenção do fungo simbionte, sua ausência culmina no decaimento e morte do jardim de fungo e posterior morte das operárias por falta de substrato alimentar, ocorrendo por fim a supressão completa da colônia.Conselho Nacional de Desenvolvimento Científico e Tecnológicoapplication/pdfporUniversidade Federal de ViçosaMestrado em EntomologiaUFVBRCiência entomológica; Tecnologia entomológicaFormiga-cortadeiraAcromymexSupressãoFipronilAnt-cutterAcromymexSuppressionFipronilCNPQ::CIENCIAS AGRARIAS::AGRONOMIA::FITOSSANIDADE::ENTOMOLOGIA AGRICOLAMecanismo de supressão de colônias da formiga-cortadeira Acromyrmex subterraneus subterraneus por fipronilFipronil-mediate suppresion of nests of the leaf-cutting ant Acromyrmex subterraneus subterraneusinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisinfo:eu-repo/semantics/openAccessreponame:LOCUS Repositório Institucional da UFVinstname:Universidade Federal de Viçosa (UFV)instacron:UFVORIGINALtexto completo.pdfapplication/pdf843146https://locus.ufv.br//bitstream/123456789/3988/1/texto%20completo.pdf7b89b9c0374c84a12c9df88c213f038eMD51TEXTtexto completo.pdf.txttexto completo.pdf.txtExtracted texttext/plain52720https://locus.ufv.br//bitstream/123456789/3988/2/texto%20completo.pdf.txt831fe4195841837d20128ae4d6dec0caMD52THUMBNAILtexto completo.pdf.jpgtexto completo.pdf.jpgIM Thumbnailimage/jpeg3444https://locus.ufv.br//bitstream/123456789/3988/3/texto%20completo.pdf.jpgaed4614b2aa70eb2244b8ab329eb0243MD53123456789/39882016-04-09 23:10:55.802oai:locus.ufv.br:123456789/3988Repositório InstitucionalPUBhttps://www.locus.ufv.br/oai/requestfabiojreis@ufv.bropendoar:21452016-04-10T02:10:55LOCUS Repositório Institucional da UFV - Universidade Federal de Viçosa (UFV)false |
