The behavioral responses of Dacne picta, a major insect pest of the shiitake mushroom (Lentinula edodes), to the odor of different stages of this mushroom were investigated by linear track olfactometer in the laboratory. The mushrooms were classified into three stages, growing, mature and decaying according to the life cycle of the mushrooms in the field. The assays were conducted on three growing stages and dried and re-hydrated mushrooms. Both male and female beetles showed chemotactic responses to the odor of all the growing stages and re-hydrated mushrooms. The rates of the beetles attracted to the odor varied among mushrooms belonging to the same stage, but these were not correlated with the amount of mushrooms.
