To examine the effects of insecticide treatments on
leafminer numbers, parasitism rates, and damage
levels, mean values were computed for each replicate
plot and one-way ANOVAs were undertaken. In
addition, repeated measures ANOVAs were undertaken
to consider the temporal component becausehese variables were repeatedly measured in the same
plots. Both linear and quadratic components of
repeat measures were assessed. To ensure that data
were normally distributed, count data were transformed
to natural logs and parasitism proportions
were transformed to arcsin values prior to analysis.
