Parental effects of Bt toxin and vitamin A on Helicoverpa armigera

The increase in the area cultivated with vitamin-enriched transgenic crops producing Bt toxin raises the question of whether the addition of vitamins will in any way mitigates the effect of the toxin on the phytophagous insects that feed on those crops. On the other hand, the parental effect that fe...

These aspects can be of great importance in the development of resistance of this species to the Bt toxin.This study received funding from Ministerio de Ciencia, Innovación y UniversidadesPublic Library of Science2022info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://doi.org/10.1371/journal.pone.0269585http://hdl.handle.net/10459.1/83946reponame:Repositori Obert UdL instname:Universitat de Lleida (UdL)Inglésinfo:eu-repo/grantAgreement/AEI/Plan Estatal de Investigación Científica y Técnica y de Innovación 2013-2016/AGL2017-84127-RReproducció del document publicat a: https://doi.org/10.1371/journal.pone.0269585PLoS One, 2022, vol. 17, núm. 7:e0269585cc-by (c) López et al., 2022info:eu-repo/semantics/openAccesshttps://creativecommons.org/licenses/by/4.0/oai:repositori.udl.cat:10459.1/839462026-06-24T12:42:17Z
