Summary

This study investigated the toxicity of Mon 863 (Cry 3Bb1) and non-Bt Mon 846 pollen to larval and adult C. mac. Pollen was incorporated as 50% of the diet. 1st instar larvae were brought to pupation and adults were fed for 30 days. Bee pollen was also used as a control. There were no differences in the effects observed on development and survival for the two corn pollen treatments, although bother were suboptimal diets compared to the bee pollen. Fecundity of adults was also not significantly different for any treatment.

Comments

Good study. Confirmed feeding using an arsenate treated control treatment. Used transgenic material. It was a subacute study, but did not look at weight or size parameters.
