Identification of an Argentinean isolate of Spodoptera frugiperda granulovirus

Revista Argentina de Microbiología, 2019
The fall armyworm, Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae), is an important maize pest. Due to the environmental impact and emergence of resistance caused by chemical pesticides and transgenic events, the use of baculoviruses becomes a safe and useful alternative for its control in integrated pest management strategies.

Insecticidal Activity of Synthetic Amides on Spodoptera frugiperda

Zeitschrift für Naturforschung C, 2006
The phytochemistry of the genus Piper (Piperaceae) has been widely studied due to the biological properties of amides from these plants. In this work, we have synthesized and evaluated the toxic effect of 11 amides against the fall armyworm Spodoptera frugiperda larvae. The naturally occurring piperine was also evaluated.
