Existe una preocupaci\u00f3n creciente sobre la p\u00e9rdida de polinizadores, fen\u00f3meno que supone una amenaza para la conservaci\u00f3n de la biodiversidad y la producci\u00f3n sostenible de alimentos a escala global. En general, hay un consenso sobre el car\u00e1cter multifactorial de este problema, y los plaguicidas han sido se\u00f1alados como uno de los factores implicados. La exposici\u00f3n de polinizadores a plaguicidas se da a trav\u00e9s de diferentes rutas, y las consecuencias de esta exposici\u00f3n dependen de si los niveles de los plaguicidas que se encuentran en el medio superan el umbral de toxicidad considerado como peligroso para su salud. Numerosos estudios muestran los efectos da\u00f1inos de ciertos plaguicidas, no s\u00f3lo a dosis letales, sino tambi\u00e9n a concentraciones menores (sub-letales) que son a menudo detectadas en los recursos florales de los que se alimentan los polinizadores. El conocimiento de los niveles de exposici\u00f3n y las mezclas de plaguicidas a las que se enfrentan los polinizadores, y de las consecuencias de esta exposici\u00f3n, son esenciales para dirigir futuras investigaciones que cubran las incertidumbres actuales, y orienten as\u00ed unas medidas estrat\u00e9gicas de regulaci\u00f3n de plaguicidas que garanticen la conservaci\u00f3n de estos importantes organismos.<\/span><\/p>\n<\/div>\n<\/div>\n

Bot\u00edas, C., S\u00e1nchez-Bayo, F. 2018. <\/strong>The role of pesticides in pollinator declines. <\/strong>Ecosistemas<\/strong><\/em> 27(2): 34-41. Doi.: 10.7818\/ECOS.1314<\/strong><\/span><\/p>\n

There is a growing concern that pollinators are in decline, potentially threatening biodiversity and sustainable food production on a global scale. In general, there is consensus on the multifactorial origin of this problem, and pesticides are regarded as one of the factors involved. Pollinators can be exposed to pesticides through different routes, and the consequences of such exposure depend on whether the levels of field exposure overlap the toxic thresholds considered as detrimental to their health. Several studies have shown the harmful effects of some pesticides not just at their lethal concentrations, but also at lower concentrations (sub-lethal) which are often detected in the floral resources consumed by pollinators. In order to direct future research that may fill our current knowledge gaps, it is essential to identify the levels of pesticides and mixtures to which bees are exposed to, and the consequences of such exposure, so as to guide pesticide regulation strategies that may guarantee the conservation of these crucial organisms.<\/span><\/p>\n<\/div>\n<\/div>\n
