Chemical pesticides have been used to control persimmon pests, however the overuse of the pesticides caused insect resistance. Herein we investigate the potential of eco-friendly organic pesticides (EFOP) on the control persimmon pests, Stathmopoda masinissa and Riptortus pedestris. Eleven commercially available EFOP were sprayed on the target insects in laboratory conditions. The chemical pesticide, buprofezin+dinotefuran wettable powder served as a positive control. In the bioassay against persimmon fruit moth, the mixture of Chinese scholar tree, goosefoot and subtripinnata extracts (EFOP-2) treatment showed the highest control efficacy: 27.7% (5 days) of survival rates. In the bioassay against bean bugs, the EFOP-2 showed the highest control efficacy: 20.0% (5 days) of survival rates. These results suggest that the mixture of three plants extracts (EFOP-2) has high and multiple potential in the management of the persimmon pests.
