A Survey Of Chemical Elicitors And Their Effectiveness As Promoters Of Plant Defense Against Herbivory By Spodoptera Frugiperda (Smith) (Lepidoptera: Noctuidae), John Gordy
LSU Master's Theses
Insect herbivores can induce a range of plant defenses. Signal pathways can be activated that result in the production of secondary metabolites. Many of these compounds can reduce insect fitness, deter feeding, and attract beneficial insects. Additionally, organic and inorganic chemicals applied as a foliar spray or soil drench can activate these plant responses. Azelaic acid, benzothiadiazole (BTH), gibberellic acid (GA3), harpin, and jasmonic acid (JA) are thought to mediate plant response to pathogens and herbivores. The effects of these elicitors on the induction of plant defenses were determined by measuring the weight gain of fall armyworm (FAW), Spodoptera frugiperda …
