Abstract The toxicity of 40 medicinal plant extracts to larvae of 2 important mushroom pests (Lycoriella ingenua Dufour and Coboldia fuscipes Meigen) was examined using a filter-paper residual contact+fumigant toxicity bioassay. Responses varied with insect and plant species used. Methanol extracts of Acanthopanax sessiliflorum cortex, Asarum sieboldii whole plant, Aster tataricus root, Carthamus tinctorius flower, Eugenia caryophillata flower bud, Illicium verum fruit, Leonurus japonicus whole plant, and Rehmannia glutinosa var.purpurea root caused 100% mortality in both L. ingenua and C. fuscipes larvae at 0.07 and 0.14 mg/cm2, respectively. These plants merit further study as potential insecticides for the control of L. ingenua and C.fuscipes.
