População, danos e parasitoides larvais de spodoptera frugiperda (j. e smith) (lepidoptera: noctuidae) em milho bt e não-bt
(Universidade Federal de Santa MariaBRAgronomiaUFSMPrograma de Pós-Graduação em Agronomia, 2012-02-16)
The occurrence of Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae), the
Fall armyworm, has led to increased adoption of Bt maize genotypes in Brazil. However, the
field impacts on parasitoids of using these ...
Variable levels of antibiosis and/or antixenosis of Bt and non-Bt maize genotypes on Dalbulus maidis (Hemiptera: Cicadellidae)
(Springer, 2021-04-28)
The corn leafhopper Dalbulus maidis (DeLong & Wolcott) (Hemiptera: Cicadellidae) poses a serious threat to the crop, causing direct and indirect damage to plants. The present study aimed to investigate the possible expression ...
Effect of bacillus thuringiensis on parasitoids and predators
(2017-06-10)
Advances in biotechnological studies have led to the development of genetically modified (GM) crops. The commercial release of transgenic plants producing Bacillus thuringiensis (Bt) insecticidal proteins has contributed ...
Bt zygosity in maize hybrids
(Universidade Estadual Paulista (Unesp), 2020-09-24)
O efeito da zigosidade de transgenes tem sido estudada em várias espécies de plantas. Contudo, apenas em 2019 investigou-se o efeito do número de alelos Bt no milho. Nesta tese, usamos híbridos de milho isogênicos hemizigotos ...
A preliminary study on the effects of a transgenic corn event on the non-target pest Dalbulus maidis (Hemiptera: Cicadellidae)
(Elsevier, 2010-06)
The inclusion of the cry gene in corn may produce direct effects on non-target pests. Our research was focused on the relationship between Bt corn germplasm, expressing the cry1F protein to control the fall armyworm ...
