The results showed that fipronil was highly toxic to M. scutellaris, with a calculated LC50 (48 h) value of 0.011 ng a.i./mu L of sucrose solution and an estimated oral LD50 (48 h) of 0.6 ng a.i./bee. Our results showed that M. scutellaris bee is more sensitive to fipronil than the model specie A. mellifera.921-924engUrucu beeEcotoxicologyPesticideLC50Artigo10.1007/s00128-012-0773-xWOS:000308551500043Acesso restrito75385560855058190000-0002-1650-257X
