Resistance of Soybean Genotypes toAnticarsia gemmatalis(Lepidoptera: Erebidae): Antixenosis and Antibiosis Characterization [PDF]

Journal of Economic Entomology, 2021
AbstractInjury by herbivores is a major biotic stress that limits soybean [Glycine max (L.) Merrill] crop production. Among the main soybean insect pests, Anticarsia gemmatalis Hübner is responsible for causing significant economic damage in soybean. The primary management strategy for this insect is chemical control and use of Bt transgenic soybean ...

Characterization of antixenosis toDichelops melacanthus(Hemiptera: Pentatomidae) in soybean genotypes [PDF]

International Journal of Pest Management, 2016
ABSTRACTSoybeans are of great importance in the world agricultural landscape, and their productive potential is significantly reduced by attacks from insect pests. Factors such as the expansion of national agricultural regions, together with no-tillage management and “off-season” maize cultivation, have favored the increase of secondary species such as
