The bioinsecticide DIPEL 2X irradiated with doses of gamma radiation up to 2.0 kGy preserves its insecticidal efficiency against larvae of the Indian meal moth, Plodia interpunctella (Hübner).
The amount of DIPEL 2X-treated food taken in by larvae irradiated with 0.1-0.7 kGy is sufficient for bringing about the death of these larvae.
