- •
Uptake and bioaccumulation of two Cry toxins by a larval coccinellid was tested.
- •
Uptake was demonstrated by presence of the toxins in pupae and adults.
- •
Bioaccumulation was shown by higher toxin concentration in pupae than prey.
- •
Cry1Ac was present 2.05× and Cry1F 3.09× higher in predator pupae than prey.
- •
This might increase persistence of Cry toxins in food webs with new exposure routes.
