Molecular identification for Helicoverpa spp. in Bt and non-Bt crops in central Argentina
Pesquisa Agropecuária Brasileira, 2022 The objective of this work was to identify, by molecular analysis, the species of the genus Helicoverpa in corn, soybean, and lucerne Bt and non-Bt crops, in central Argentina. A total of 1,343 carterpillars were analyzed by PCR-RFLP. Helicoverpa zea was
