"Bee, pollen, honey and beeswax samples were collected from control and treated plots from Larose Forest after spraying with fenitrothion for budworm control. Residues of the insecticide, its oxygen analog and its cresol hydrolysis product were determined in the collected samples from the control plot after spiking and extracting with acetonitrile followed by hexane partition and charcoal-Celite column cleanup. The parent compound and the two iaetabolites were separated by differential elutlon using a deactivated silica-gel column. Fenitrothion and its oxon, were determined by GLC using a flame photometric detector sensitive to phosphorus and the cresol by a Ni 63 electron-capture detector. Recoveries of the insecticide and its two metabolites from spiked substrates averaged over 80% and residues may be determined at levels as low as 0.005 ppm. No oxon or cresol derivatives of the parent compotmd were found in any of the substrate samples analysed. The GLC methods described here for the analysis of fenitrothion residues in honeybees and their products were found to be practical, rapid and precise"--Summary, pages 21-22.
