A biota nos ecossistemas aquáticos é geralmente exposta a diversas condições de
estresse, como variações ambientais naturais e distúrbios antropológicos, incluindo as
descargas de poluentes nos recursos hídricos. Sendo assim importante a realização de estudos
que avaliem os efeitos desses poluentes sobre os ecossistemas. O malathion é um exemplo de
poluente, pois, é um inseticida comumente utilizado como defensivo agrícola em culturas ao
redor do mundo e, embora apresente baixa toxicidade para espécies de mamíferos, espécies
aquáticas podem ser sensíveis mesmo a pequenas concentrações. Dentre os diversos
organismos aquáticos os crustáceos tem se destacado como organismos sensíveis para avaliar
a poluição do ecossistema aquático. Nesse sentido, o objetivo do presente trabalho foi avaliar
os efeitos do malathion sobre camarões Macrobrachium amazonicum através da obtenção da
DL50 e da análise morfológica de suas brânquias. Para isso, camarões nativos do rio Grande
foram capturados e aclimatados ao ambiente laboratorial para a realização de bioensaios. Os
camarões foram divididos em grupos de dez animais cada e expostos a concentrações
crescentes do inseticida por 48 horas. Nossos achados mostraram que a DL50 foi atingida a
0,73 mg/L de malathion, e que alterações relevantes na arquitetura das brânquias podem ser
observadas em camarões expostos a concentrações de 1,25 a 1,5 mg/L do inseticida. Este é o
primeiro estudo demonstrando que mesmo em curto prazo, o malathion interfere na estrutura
microscópica das brânquias de camarões do gênero Macrobrachium, e vem contribuir para
uma melhor compreensão dos efeitos promovidos por determinados defensivos agrícolas
sobre organismos aquáticos que, comumente ficam expostos a estes. / Biota in aquatic ecosystems is usually exposed to various stress conditions, like
natural environmental variations and anthropological disturbs including pollutant discharges
into water resources. Malathion is an insecticide commonly used as an agricultural pesticide
in crops around the world, and although it presents low toxicity to mammalian species,
aquatic species may be sensitive even at small concentrations. Among the various aquatic
organisms, crustaceans have distinguished themselves as sensitive organisms to evaluate the
pollution of the aquatic ecosystem. In this sense, the objective of the present work was to
evaluate the effects of malathion on Macrobrachium amazonicum shrimps by obtaining LD50
and morphological analysis of the gills. For this, native prawns of the Rio Grande were
captured and acclimated to the laboratory environment for the realization of bioassays. The
shrimp were divided into groups of ten animals each and exposed to increasing concentrations
of the malathion for 48 hours. Our findings showed that the LD50 was reached at 0.73 mg/L
malathion, and that relevant changes in the architecture of the gills can be observed in shrimps
exposed to concentrations of 1.25 and 1.5 mg/L of the insecticide. This is the first report
demonstrating that even in the short term, malathion interferes in the microscopic structure of
Macrobrachium shrimp gills, and contributes to a better understanding of the effects promoted
by certain pesticides on aquatic organisms that are commonly exposed to these.
