portuguesConsiderando os danos causados por moluscos terrestres em regioes produtoras de morangueiro no Sul do Brasil, neste estudo tivemos como objetivos i) identificar as especies de moluscos associadas a Fragaria x ananassa em propriedades rurais localizadas em municipios do estado do Parana; ii) descrever e ilustrar as caracteristicas morfologicas e conquiliologicas diagnosticas das especies de moluscos encontradas; iii) construir uma chave pictorica com base em caracteristicas morfologicas e conquiliologicas; iv) analisar parasitologicamente amostras de duas especies coletadas em marco de 2017, visando a identificacao de possiveis nematodeos de interesse medico. A determinacao taxonomica foi realizada atraves da analise morfologica das amostras e a parasitologica atraves da tecnica de digestao artificial. Foram identificados os caracois Bradybaena similaris (Bradybaenidae), Rumina decollata (Subulinidae), Deroceras leave (Agriolimacidae), Limacus flavus (Limacidae) e Meghimatium pictum (Philomycidae). Rumina decollata, L. flavus e M. pictum foram pela primeira vez registradas causando danos ao morangueiro no Brasil. Larvas de interesse medico e/ou veterinario nao foram encontradas associadas as amostras analisadas. Os principais caracteres diagnosticos para cada especie sao descritos e ilustrados, assim como discutida a potencialidade das mesmas como pragas agricolas e hospedeiras de nematodeos de importância medico-veterinaria. Os resultados auxiliam a identificacao destas especies na cultura do morangueiro, servindo de base para estudos de bioecologia e controle nestas areas.

Taxonomic determination of the mollusks was performed through morphological analysis of samples, and parasitological analysis was carried out using artificial digestion. The following gastropod species were identified: Bradybaena similaris (Bradybaenidae), Rumina decollata (Subulinidae), Deroceras leave (Agriolimacidae), Limacus flavus (Limacidae), and Meghimatium pictum (Philomycidae). Rumina decollata, L. flavus,and M. pictum were recorded for the first time as damaging strawberries in Brazil. No larvae of medical or veterinary importance, associated with samples, were reported. The main diagnostic features are described and illustrated. Besides, the potential of the gastropods as crop pests and vectors of nematodes associated with zoonotic diseases are discussed. Results can facilitate identification of gastropod species in strawberry crops and provide background information for future studies on bioecology and pest control.
