Table 3. Mean number of L. decolor adults ± SE per vial (for vials in which the initial population was 5 adult females of L. decolor alone, or 5 adult females of L. decolor with 5 adult females of L. bostrychophila, or 5 adult females of L. decolor 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.

Within each column and temperature, means followed by the same letter are not significantly different; where no letters exist, no significant differences were noted (Tukey-Kramer HSD test at p = 0.05; in all cases, df = 2, 24).
