When white cotton balls impregnated with anthranilic acid, the pheromone released by the female black chafer Holotrichia loochooana loochooana, and untreated black cotton balls were paired and placed side by side in the field, males were observed to make pinpoint landing significantly more frequently on the latter.
Then we tried to examine characteristic functions of visual and olfactory cues in male flight location of H l. loochooana, with results of field experiments with models as visual stimuli and/or the pheromone sources are paired but separately presented.
(1) A male H. l. loochoana landed on and attempted to copulate with an untreated black ball placed 5 cm from a pheromone-treated white ball on Scaevola cericea leaves.
