Neotropical brown stink bug (Euschistus heros) resistance to methamidophos in Paraná, Brazil
Pesquisa Agropecuária Brasileira 45 (7), 767-769
Abstract: The objective of this work was to evaluate the soybean neotropical brown stink bug (Euschistus heros) resistance to methamidophos through laboratory bioassays. Bioassays were carried out using populations of adults and nymphs of Euschistus heros in the last instar collected in soybean crops in Paraná State. Highest frequencies of genotypes resistant to methamidophos were observed in Alvorada do Sul, Toledo and Nova Santa Rosa, PR. Populations from Bela Vista do Paraíso, Araruna, Campo Mourão, Mariluz, Cascavel, São João do Ivaí, and Mamboré were more susceptible to methamidophos. However, an increase on resistant genotypes in this locations cannot be discarded.
