A Rapid, Inexpensive, Quantitative Procedure for the Extraction and Analyses of Penncap-M (Methyl Parathion) from Honeybees {Apis mellifera L.), Beeswax, and Pollen A rapid, inexpensive, quantitative procedure for the acetone-o-xylene (19:1) extraction of Penncap-M (methyl parathion) from honeybees (Apis mellifera L.), beeswax, and pollen is reported. Mean recoveries for six concentrations of methyl parathion were 98.0, 97.8, and 94.2% from honeybees, beeswax, and pollen, respectively. Mean recovery of methyl parathion from honey seeded at five concentrations of Penncap-M was 87.3%.Penncap-M insecticide is a water-based slurry of microcapsules (30-50-µ cross-linked nylon polymer) con-
