Fig. 2.

Reproductive capacity (in vitro) of Steinernema carpocapsae sib-crosses and outcrosses. In vitro reproductive capacity of sib-crosses (gray bars) and outcrosses (white bars) on lipid agar plates, measured by counting the number of progeny directly on the plate upon which a cross was performed. Letters over each bar indicate statistically significant differences between the in vitro reproductive capacity of a given line and all other lines assayed at α = 0.05. Error bars indicate 1 S.D. from the average of the replicates.
