Defining the Toxicity of Novel Insecticides against Fall Armyworm

The objective of this experiment was to evaluate fall armyworm susceptibility to selected insecticides.  All tests were performed on larvae (L3 stage) from a laboratory colony originating from collections in cotton and corn.  Insecticides were incorporated into meridic diet and larval mortality measured at 96 HAT.  Dose-mortality responses were summarized and LC₅₀’s used to compare toxicity among compounds.
