Summary Collection or storage of insects in 70% IPA was found to cause loss of body weight, major loss of nonpolar insecticides from submerged specimens, and transfer of insecticide to previously uncontaminated specimens. These effects may by no means be limited to mirex, since any chlorinated hydrocarbon is relatively lipophilic and may behave similarly. Residues reported for treated insects that have been collected or stored in alcohol may have been reduced to 12% of the original value. Moreover, small untreated vertebrates and invertebrates trapped in alcohol with insecticideladen insects are likely to absorb significant amounts of insecticide from the solution. The changes in residue levels owing to the 70% IPA used, though variable, were found to be as large as an order of magnitude, and the use of a correction factor would be badly misleading.
