Abstract：
- In order to find effective control methods for Aphrodisium sauteri Matsushita，the reproductive behavior of this longhorn beetle was observed and a field test for trapping adultsconducted． The results show that females and males mutually attract each other at short distances， but at long distances females tend to attractmales． In a laboratory experiment，the duration of calling behavior increased with adult age．Mating mainly took place in daytime． 1st—14th day females and 2nd—13th day males could mate several times after they left eclosion holes． A complete mating lasted 70. 12min on average．The average protective duration after mating was 3. 86 min． In a complete mating，the duration of mating，interval of mating and frequency of mating differed among adults of different ages． The interval of mating was always longerthan the duration of mating． Previous reproductive experience had a greater influence on males’mating behaviors than on female’s．The average preoviposition period of females was 30. 71 h． Females took，on average，99.58 s to lay an egg，and oviposition time increased with female age． The average number of eggs laid by a female was 7. 89 in one day and the total number of eggs laid by a female in her life time was 26. 20. Females touched the bark surface with their ovipositors tofind oviposition sites and usually laid eggs in daytime．Eggs were mainly laid in cracks in bark and scars on branches．Usually only one egg was laid at a time and the eggs were uncoated．
