Insect visitors to the flowers of peaches, one of which was the pollen nonviable variety “Yamato-hakuto”, and the other was the pollen viable variety “Hakuho”, were investigated at Nara Experiment Station in 1954 and 1955. In the blooming season of 1954 when it was gene-rally cloudy and rainy, the insect visitors were classified into 59 species of 21 families. Diptera were most frequently observed to the flowers of peaches, especially to the “Hakuho”, and “Hymenoptera” came next in number to the “Hakuho”. In the blooming season of 1955 when it was generally fine, the insect visitors were classified into 46 species of 20 families. Hymenoptera were, most frequently observed to the flowers of peaches, especially to the “Hakuho” and Diptera came next in number. Lepidoptera and Coleoptera were rarely observed to the flowers of peaches in both years. The time of their visit was not definite in 1954, but in 1955 they visited most frequently during a few hours around noon, and least in early morning and evening. When it rained, their visit was very seldom. It is guessed that their visit has: something to do with temperature, rainy weather, and the conditions of flowers.
