Assessment of the Effects of Herbivore Induced Plant Defenses in Corn (Zea mays L.) on Oviposition and Larval Competition of Corn and Rice Strain Fall Armyworm (Spodoptera frugiperda Smith)



2017 |       Funded by:



The Fall Armyworm is an important pest of maize in the United States, and recent outbreaks of this pest in Africa have raised it to the front of the scene as a pest of major concern. In this project, we aim at disentangle the chemical ecology of the moth’s oviposition preferences. Understanding how gravid females select their hosts to lay eggs on will open avenues for the development of ecologically-sound, affordable, and sustainable approaches to control this voracious pest.
