Preferência alimentar de Anticarsia gemmatalis Hübner (Lepidoptera: Noctuidae) por cultivares de soja

Abstract: Resumo A soja é um produto agrícola relevante para a economia do Brasil, mas sua produtividade é reduzida pelo ataque da lagarta Anticarsia gemmatalis. No controle, é necessário consolidar pesquisas com alternativas não químicas, destacando-se a resistência de plantas, importante ferramenta do MIP. Para tanto, este trabalho avaliou a atratividade e a não preferência alimentar, com e sem chance de escolha, de lagartas de primeiro instar A. gemmatalis por folhas de diferentes cultivares de soja. Os testes foram … Show more

“…The use of conventional and transgenic soybean cultivars resistant to lepidopteran larvae is a major tactic in soybean integrated pest management (IPM) (Fugi et al, 2005;Souza et al, 2012Souza et al, , 2014Franco et al, 2014;Boic ßa J unior et al, 2015), and searching for resistance genes in a range of genotypes is needed to contribute to the success of soybean IPM. Many factors related to both the plant and the insect can affect the expression of plant resistance and generate variability when screening plant genotypes for resistance to insects (Smith, 2005).…”

“…Although some studies have evaluated soybean resistance to A. gemmatalis ( Beach and Todd 1988 ; Hoffmann-Campo et al 1994 ; Fugi et al 2005 ; Piubelli et al 2005 ; Franco et al 2014 , 2017 ), there are few studies characterizing resistance of a large number of soybean genotypes (with high genetic variability). Therefore, to identify new resistance sources, this study characterized the expression of antibiosis and antixenosis in 30 soybean genotypes under laboratory and greenhouse conditions.…”
