NS = not significant;

* P<0.05;

** 0.001<P<0.05;

*** P<0.001 by Fisher exact test for egg masses, using n = 117 egg masses minus number completely predated

(11 fresh and 15 frozen), or lost (2 egg masses each), as total available egg masses in which to observe parasitism frequency. Observed rate of parasitism include emerged and unemerged parasitoids; marginal rate of parasitism mb = db/(1-ma), where db = observed death rate from parasitism and ma = rate of death from predation and other causes (lost and undetermined mortality). Caged egg mass treatment is not included.
