Window of opportunity for Ooencyrtus telenomicida as function of host egg age and interspecific parasitism status.
The emergence of Ooencyrtus telenomicida from (A) unparasitized 1 to 5 day old Nezara viridula eggs (Ot); (B) 1day old N. viridula eggs parasitized by Trissolcus basalis that were then parasitized by O. telenomicida 1 to 8 days later (Tb1-Ot); and (C) 3 day old N. viridula eggs parasitized by T. basalis that were then parasitized by O. telenomicida 1 to 8 days later (Tb3-Ot).

Life history parameters of Ooencyrtus telenomicida when developing in different host types.
The number emerging (A), sex ratio (B), developmental time and size of female (C, E) and male (D, F) Ooencyrtus telenomicida adults developing in (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).

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.
