Influence of corn genotypes, fertilizer and insecticide on population and damage of Spodoptera frugiperda (J.E. Smith, 1797) during two sowing periods

Experiments were carried out at FCAV/UNESP - Jaboticabal SP Brazil, during 1997-1998 and 1998-1999 agricultural years to analyze the influence of chemical fertilizer and insecticide on population of Spodoptera frugiperda (Noctuidae) in four corn genotypes, Zea mays (Poaceae), during “water” and “dry...

Genotypes C-805, C-505, C-125, C-606, C-929 and C-747 were used and experiments were undertaken according to randomized block design with 16 treatments and 4 replications. Attack of S. frugiperda in 10 plants per part was weekly evaluated, based on visual scale of grades; moreover, the number and size of caterpillars were determined. Results showed that genotype C-505 was the least attacked by S. frugiperda, whilst the most attacked were C-805 and C-125. Population and damage were less when C-606 and fertilizer application were associated. Insecticide avoided higher damages and larger numbers of caterpillars in all genotypes.

Os genótipos utilizados foram C-805, C-505, C-125, C-606, C-929 e C-747, em delineamento de blocos ao acaso no esquema fatorial (2x2x4) e 4 repetições. Foi avaliado o ataque de S. frugiperda em 10 plantas por parcela, semanalmente, baseando em escala visual de notas, e realizadas observações quinzenais do número e tamanho de lagartas. O genótipo menos atacado pela S. frugiperda foi o C-505, enquanto os maiores se destacaram o C-805 e C-125; a população e os danos foram menores quando se associou C-606 e adubação; o uso de inseticida possibilitou um menor dano e número de lagartas em todos os genótipos; na época “de safrinha” a adubação interferiu pouco na incidência e nos danos da pragaUniversidade Estadual de Maringá2008-05-09info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciAgron/article/view/257210.4025/actasciagron.v23i0.2572Acta Scientiarum.
