Abstract: Excerpts from the report: This publication is based on a large-scale study of the use of malathion-treated raisin-drying trays as a means of protecting raisins from insects during the periods of drying and storage. The tests also included laboratory bioassay tests and microanalyses. The results of the 1962-63 study are reported in three parts. In part I, the levels of malathion residue and the insect populations were determined and taste tests were made. In part II, bioassay studies evaluated the effectiveness of the different levels of malathion residue under controlled laboratory conditions. In Part III, insect and insect fragment counts were determined by a laboratory washing process (microanalysis).
