The Data Reporting Guideline (DRG) for the Honey Bee Studies, Series 141-1, 141-2 and 141-5, gives guidance to pesticide registrants on the format for their study report so that the Agency can review it efficiently. It clarifies sections in the existing Pesticides Assessment Guidelines, Subdivision L, on data reporting and provides an outline for study reports and describes the topics and the order in which they should be addressed. Examples of tables are also provided. The guideline actually contains formats for the preparation of reports for three studies: Honey Bee Acute Contact LD50, Series 141-1; Honey Bee-Toxicity of Residues on Foliage, Series 141-2; and Field Testing for Pollinators, Series 141-5. Data submitters can use the DRG in preparing their reports for submission to EPA to meet 40 CFR 158 requirements for the registration of pesticides. The DRG for Series 141-1, 141-2, and 141-5, Honey Bee Studies is the only DRG published by the National Technical Information Service as an addendum to Subdivision L of the Pesticide Assessment Guidelines.
