dc.description | The toxicity of methamidophos on the shrimp Litopenaeus vannamei was evaluated using acetylcholinesterase (AChE) activity, behavior, and feeding rate as effect criteria. The biochemical characterization of the soluble cholunesterase (ChE) present in both muscle and eye tissues of L. vannamei was performed in a first phase of the study. In both tissues, almost full inhibition of enzyme activity by eserine sulfate was found, indicating that the measured activity is mainly from ChE and not from other esterases. The highest rate of substrate hydrolysis was found when acetylthiocholine was used as substrate. To evaluate the effects of methamidophos on L. vannamei AChE, behavior, and feeding rate, shrimps were exposed for 24 h to several sublethal concentrations of methamidophos. Significant effects of the pesticide on behavior and AChE were found, with behavior being a more sensitive endpoint than AChE inhibition. Feeding rate was not a sensible endpoint under conditions tested. | es_ES |

La caracterización bioquímica de la colinesterasa soluble (ChE) presente en ambos músculos Y tejidos oculares de L. vannamei se realizó en una primera fase del estudio. En ambos tejidos, la inhibición casi completa de la actividad enzimática Se encontró sulfato de eserina, lo que indica que la actividad medida es principalmente de ChE y no de otras esterasas. La mayor tasa de Se encontró hidrólisis de sustrato cuando se usó acetiltio colina como sustrato. Evaluar los efectos de methamidophos en L. vannamei AChE, el comportamiento y la velocidad de alimentación, los camarones fueron expuestos durante 24 h a varias concentraciones subletales de metamidofos. Significativo Efectos del plaguicida sobre el comportamiento y la AChE, siendo el comportamiento un punto final más sensible que la inhibición de la AChE. Alimentación No era un criterio de valoración razonable en las condiciones ensayadas. | es_ES |
