Determination of insecticidal potential of selected plant extracts against fall armyworm (Spodoptera frugiperda) larvae

Abstract The fall armyworm, Spodoptera frugiperda (J.E. Smith), is a devastating pest that attacks a wide range of crops, including sugarcane, rice, and maize. The purpose of this study is to evaluate the toxicity potential of native plant extracts (Azadirachta indica, Eucalyptus globulus, Parthenium hysterophorus, Cannabis sativa, Citrullus colocynthis, Nicotiana tabacum) against S. frugiperda. Four different concentrations (50, 100, 200, and 400 ppm) of the ethanolic plant extracts was evaluated against S. frugiperda third-instar larvae to determine their median lethal
