Samples of plankton were collected in a pond excavated in Rio Preto da Eva, Amazon State, Brazil. Parasitized C. macropomum were captured to collect N (N.) buttnerae adults and to evaluate parasitism and parasite indices. All of the sampled fish were heavily infected with N. (N.) buttnerae. The intermediate host was a species of Ostracoda. For the description of the larvae development, a laboratory experimental procedure was used. A total of eleven larval stages, one acanthus phase, and ten acanthella phases were found and the 11th stage was the infecting one. Attempts to cultivate Ostracoda until the development of the infecting stage larva have failed. Being cultivated until the maximum of 26 days, where they were observed the larvae in juvenile stage. All the larvae stages were found in a single Ostracoda species. The larval stages were described morphologically and compared to other species of the Neoechinorhynchidae family with previously described life cycles. Foi descrito o ciclo de vida de Neoechinorhynchus (Neoechinorhynchus) buttnerae, parasita de Colossoma macropomum, baseado na descrição morfológica de seus estágios larvais e identificação de seu hospedeiro intermediário. Foram coletadas amostras de plâncton de um viveiro escavado no município Rio Preto da Eva, Amazonas, Brasil. Foram analisados exemplares de C. macropomum parasitados para coleta dos adultos de N (N.) buttnerae e avaliar o parasitismo e os índices parasitários. Todos os peixes necropsiados estavam parasitados N. (N.) buttnerae. O hospedeiro intermediário de N (N.) buttnerae foi uma espécie de Ostracoda. Para a descrição dos estágios larvais de N. (N.) buttnerae foi utilizado método experimental em laboratório. Foi encontrado um total de onze estágios larvais, uma fase de acântor, e dez fases de acantela e o 11º estágio o infectante. Tentativas de se cultivar o Ostracoda até o desenvolvimento da larva em estágio infectante falharam, sendo cultivado até no máximo 26 dias, onde foram observadas as larvas em estágio juvenil. Todos os estágios foram encontrados em uma única espécie de Ostracoda. Os estágios larvais foram descritos morfologicamente e comparados com outras espécies da família Neoechinorhynchidae com ciclos de vida já descritos. 2020-02-13T18:22:28Z 2020-02-13T18:22:28Z 2017-04-20 Dissertação https://repositorio.inpa.gov.br/handle/1/11380 http://lattes.cnpq.br/5684718320348030 por Attribution-NonCommercial-NoDerivs 3.0 Brazil http://creativecommons.org/licenses/by-nc-nd/3.0/br/ application/pdf Instituto Nacional de Pesquisas da Amazônia - INPA Biologia de Água Doce e Pesca Interior - BADPI |

| description |
The life cycle of Neoechinorhynchus (Neoechinorhynchus) buttnerae, parasite of
Colossoma macropomum, was described based on morphological descriptions of its
larvae’s development and the identification of its intermediate host. Samples of
plankton were collected in a pond excavated in Rio Preto da Eva, Amazon State, Brazil.
Parasitized C. macropomum were captured to collect N (N.) buttnerae adults and to
evaluate parasitism and parasite indices. All of the sampled fish were heavily infected
with N. (N.) buttnerae. The intermediate host was a species of Ostracoda. For the
description of the larvae development, a laboratory experimental procedure was used. A
total of eleven larval stages, one acanthus phase, and ten acanthella phases were found
and the 11th stage was the infecting one. Attempts to cultivate Ostracoda until the
development of the infecting stage larva have failed. Being cultivated until the
maximum of 26 days, where they were observed the larvae in juvenile stage. All the
larvae stages were found in a single Ostracoda species. The larval stages were described
morphologically and compared to other species of the Neoechinorhynchidae family with
previously described life cycles. |
