The control failures of FAW by Bt maize increased the use of insecticides for their control. However, no information is available on the interaction between resistant FAW and their response to insecticides. Here, we evaluated the survival of FAW strains on Bt and non\u2010Bt maize in laboratory and field conditions, and their susceptibility to insecticides.<\/jats:p><\/jats:sec><jats:sec><jats:title>RESULTS<\/jats:title><jats:p>In the laboratory, resistant FAW larvae reared on Bt and non\u2010Bt maize showed a similar susceptibility to spinetoram (LC<jats:sub>50<\/jats:sub>\u2009=\u20090.16\u20130.18\u2009\u00b5g a.i. cm<jats:sup>\u22122<\/jats:sup>) and chlorfenapyr (LC<jats:sub>50<\/jats:sub>\u2009=\u20090.17\u20130.20\u2009\u00b5g a.i. cm<jats:sup>\u22122<\/jats:sup>).

In contrast, heterozygous strains had similar susceptibility to the susceptible strain. In field trials, no differences in FAW survival were detected between strains when the commercial dose of two insecticides was applied in Bt and non\u2010Bt maize.<\/jats:p><\/jats:sec><jats:sec><jats:title>CONCLUSION<\/jats:title><jats:p>FAW strains surviving on Bt and non\u2010Bt maize, at the same development stage, have similar susceptibility to insecticides.
