Table 1 . "Artificial" flies were prepared by mixing RNA and DNA standards to target insect nucleic acid concentrations (n=3 unless noted in table) and processing as a sample. RNA and DNA concentrations (µg ml-1)plus or minus standard errors are reported. RNA/DNA ratios are calculated from initial estimated RNA/DNA. Percent recovery is percent of nucleic acid measured compared to actual. Mean values for the 5 experiments are given with standard errors.
