Troubleshooting- Insect colony style

So, let's say that hypothetically, I'm trying to build a colony of Orius insidiosus, but I'm having some ridiculous problems regarding reproductive diapause. We've upped the photoperiod, temperatures, humidity, and virtually replicated past successful colonies. Can anyone think of some reasons that we might be having some issues getting this group- or any other colony of bugs- to reproduce. Green bean is the oviposition substrate... I'm just kind of stumped. Maybe I'm missing something obvious? Hmm.

Prey?
Do they need the presence of prey to become active? Are there mites, aphids, whatever around?

 
We're using eggs
Ephestia eggs seem to work well in other lab settings, but we're making do with T. ni eggs and neonates. That doesn't seem the problem- gonna try and see if changing the oviposition substrate might work- if not, I'm outta luck until they start showing up again in the wild :P Thanks though!
