Mean number of L. bostrychophila adults ± SE per vial (for vials in which the initial population was 5 adult females of L. bostrychophila alone, or 5 adult females of L. bostrychophila with 5 adult females of L. decolor, or 5 adult females of L. bostrychophila with 5 adult females of L. paeta) at 35, 70, 105, 140, and 175 days after the introduction of the initial population at two temperatures.
