Interspecific interference competition effect on parasitoid progeny production.

<p>The blank, punctate and netted bars represent the number (mean ± SE) of <i>En</i>. <i>sophia</i> (A) or Er. <i>hayati</i> (B) progeny when introduced into the leaf cage alone (no subsequent parasitoid), first [introduced before a Er. <i>hayati</i> (A) or <i>En</i>. <i>sophia</i> (B) female] or second [introduced after a Er. <i>hayati</i> (A) or <i>En</i>. <i>sophia</i> (B) female], respectively. Note: * above each bar indicates the number of progeny that differed significantly between alone treatment and both the interference treatments, respectively (Mann-Whitney test, <i>p</i> < 0.05). Numbers in parentheses above bars indicate the sample sizes of treatments.
