Summary Age‐specific effects of inbreeding on fecundity were assayed for adzuki bean weevil Callosobruchus chinensis by comparing inbred lines and their cross. Four consecutive full‐sib matings reduced only 10.3 percent in total fecundity, and did not decrease early fecundity at all until third day from the onset of reproduction. It is suggested that recessive detrimental genes have been eliminated from the early period of adult life span when reproductive value is high. There was a slight tendency that inbreeding depression increased as age proceeded though not statistically significant.
