These fungi were not pathogenic to cochineal. This the first report of the efficiency of Isaria spp. against this the insect. The bioassays of the compatibility of the insecticides acetamiprid and thiametoxam with species of Isaria indicate the possibility of the joint use of these products in studies on the control of D. opuntiae. 2019 otro 0065-1737 https://www.redalyc.org/articulo.oa?id=57560444039 https://www.redalyc.org/journal/575/57560444039/ https://www.redalyc.org/journal/575/57560444039/html/ https://www.redalyc.org/journal/575/57560444039/57560444039.epub https://www.redalyc.org/journal/575/57560444039/movil 10.21829/azm.2019.3502249 en http://www.redalyc.org/revista.oa?id=575 Acta Zoológica Mexicana (nueva serie) application/pdf Instituto de Ecología, A.C.
