It was available to store both nymphs and adults of Geocoris pallidipennis at 5℃ for 3 weeks without negative effects on their survival, fecundity, and Bamisia tabaci nymph predation. Up to 140 days, it was also possible to store Micromus angulatus adults at low temperature, showing approximately 50% cumulative survival rate, but over 2 week cold storage was not suitable for their fecundity. With the increase of cold storage duration, the aphid predation by M. angulatus decreased, but it could be possible to cold store until 5 weeks without a significant effect on their aphid predation. Thus, short term cold storage of G. pallidipennis and M. angulatus could be useful for inundative biological control.
