Table 1. The proportion of Ooencyrtus telenomicida females selecting a (I) 1 day old, unparasitized Nezara viridula eggs (Ot), (II) 2 day old N. viridula eggs that had been parasitized by Trissolcus basalis when they were 1 day old (Tb1 - Ot2), (III) 4 day old N. viridula eggs that had been parasitized by T. basalis when they were 3 days old (Tb3 - Ot4), or (IV) 10 day old N. viridula eggs that had been parasitized by T. basalis 7 days earlier (Tb3 - Ot10) as their first oviposition site in a choice bioassay.
