Fig. 3. (A) The number of hosts parasitized when E. pennicornis females were provided with populations of L4, L5, L6 (and mixed L4–6 hosts) and (B) the number of eggs laid. Values are means ± S.E.M. For N values, see text. Bars headed by different letters are significantly different (one-way ANOVA of log-transformed data, P<0.05). (C,D) The relationship between longevity and the number of hosts parasitized for E. pennicornis females exposed to (C) L6 populations (linear regression analysis: y=0.5752x–0.5772, r²=0.62, F_1,1321.56, P<0.001) and (D) mixed L4–L6 populations (linear regression analysis: y=0.5506x–0.044, r²=0.77, F_1,13=43.5, P<0.001).
