Resumo: A well known case of ineffective natural biological control: the puzzling coexistence of the coffee leaf miner, Leucoptera coffeellum (Guérin-Mèneville), and its natural enemies was analyzed. Despite being a suitable prey to eight parasitoid species and three wasp species, all occurring simultaneously, the coffee leaf miner too often presents populations far above the damaging level for the coffee plantation. It is demonstrated that predatory wasps and parasitoids interact negatively, possibly because predatory wasps kill parasitized miner's larvae. In doing so, predatory wasps indirectly kill parasitoids, thereby impairing the efficacy of the natural biological control. It is warned that biological control programs should be based on knowledge of food web interactions, rather than simply on strategies involving introduction of exotic natural enemies.

Apesar de ser uma presa adequada a oito espécies de parasitóides e três espécies de vespas predadoras, todas ocorrendo simultaneamente, o bicho-mineiro-do-cafeeiro apresenta, muito frequentemente, populações acima do nível de dano econômico para o cafezal. Foi demonstrado que vespas predadoras e parasitóides interagem negativamente, possivelmente porque vespas matam as lagartas de bicho-mineiro-do-cafeeiro parasitadas. Fazendo assim, vespas predadoras matam parasitóides indiretamente, prejudicando a eficiência do controle biológico natural. Conclui-se que programas de controle biológico deveriam estar baseados em conhecimentos de interações tróficas, ao invés de simplesmente se basearem em estratégias que envolvam a introdução de inimigos naturais exóticos.Anais da Sociedade Entomológica do Brasil2019-10-01T14:24:05Z2019-10-01T14:24:05Z2000-09info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlepdfapplication/pdf1981-5328http://dx.doi.org/10.1590/S0301-80592000000300013https://locus.ufv.br//handle/123456789/27186engv. 29, n. 03, p. 507- 514, set. 2000Reis Jr, RonaldoSouza, Og deVilela, Evaldo F.info:eu-repo/semantics/openAccessreponame:LOCUS Repositório Institucional da UFVinstname:Universidade Federal de Viçosa (UFV)instacron:UFV2024-07-12T08:04:49Zoai:locus.ufv.br:123456789/27186Repositório InstitucionalPUBhttps://www.locus.ufv.br/oai/requestfabiojreis@ufv.bropendoar:21452024-07-12T08:04:49LOCUS Repositório Institucional da UFV - Universidade Federal de Viçosa (UFV)false
