DETERMINAÇÃO DO NÚMERO DE ESTRUTURAS FRUTÍFERAS DO ALGODOEIRO DANIFICADAS POR LAGARTAS DE Spodoptera frugiperda (J. E. SMITH, 1797) (LEPIDOPTERA, NOCTUIDAE) EM DIFERENTES ÉPOCAS DE DESENVOLVIMENTO DA CULTURA
2007
The damage caused by the larvae of Spodoptera frugiperda (J. E. Smith, 1797) in relation to the number of fruit structures damaged by the larvae at different periods during the development of the cotton plant cultivar IAC-17, has been studied. The periods of infestation did not present significant differences. However, the number of insects affect significantly the damage to the cotton bolls and the total damage to the fruit structures. The larva of S. frugiperda destroyed 3.8 fruit structures during its development.
