1. When studying the effects of Cry proteins on biological control efficacy, how many trophic levels must be studied to determine the potential for ecological hazard?

2. EPA determined that a new insecticide was not neurotoxic but did affect the endocrine system by virtue of evidence for forming a ligand with the estrogen receptor. The most sensitive endpoint from chronic dietary exposure in a rodent was more than 10% weight loss in females at an exposure dose of 0.01 mg/kg/day. The NOAEL was 0.005 mg/kg/day.

What reference dose would EPA set for this new insecticide __________

What would the population adjusted dose be if EPA decided to apply the maximum FQPA safety factor owing to concerns about endocrine system toxicity _____________
