Analysis of variance was performed to compare the number of
parasitoid eggs, larval and pupal developmental time, and the
number of female and male offspring produced between different
treatments. Fisher’s LSD multiple comparison tests were
performed when appropriate. Oviposition preference by female
parasitoids and mortality rates were analyzed by paired Z-test
and egg positioning within fall armyworm larvae by Fisher exact
test. The size of the larval head capsule from the two fall
armyworm host strains fed different diets was transformed to
the natural logarithm, as recommended by LaBarbera (1989),
before performing the ANOVA test. The statistical program Systat
V. 12 was used for the statistical analysis
