Antifeedant screening of thirty‐nine local plants with fall armyworm larvae

Abstract

Thirty‐nine local plants of Maryland were collected, ground, and extracted with two solvents. The extracts were incorporated into an artificial diet and tested for antifeedant activity vs. a control against fall armyworm first‐instar larvae, Spodoptera frugiperda (J. E. Smith). Several extracts resulted in larvae that weighed less than 10% of the average weight of the control larvae.

Key words:

• antifeedant
• fall armyworm
• Spodoptera frugiperda
