Lab studies to determine the effects of feeding pollen expressing Cry 1Ab protein to Coleomegilla maculata, Orius insidiosus, and Chrysoperla carnea. There were no significant acute effects on preimaginal development or survival. A field survey of predator populations was also conducted and found no significant detrimental effects on predator populations.
This is a thorough study utilizing both field and laboratory components.
