説明

Adults of Stathmopoda masinissa, one of the main pests attacking the Japanese persimmon, Diospyros kaki, mainly emerged at the time around sunset in both the 1st and 2nd periods of adult emergence. Mating behavior took place in the twilight before sunrise. Mating was usually performed once by both the male and the female. Some virgin females displayed calling behavior on the day of their emergence. In the 1st period of adult emergence, the percentage of females in the calling position increased to about 70% one day after emergence, while in the 2nd period of adult emergence, it remained at about 35% even two days after emergence. Calling behavior was not adopted when the temperature fell below 14°C. No male moth was caught in the virgin female trap when the wind velocity exceeded 2.0m per second. Marked male moths were caught in a virgin female trap which was separated by a distance of 20m from the release point, the percentage of recaptures in relation to the total number of moths released being 28.0% on an average.
