Yun found a damage rating scale to be the most useful criterion
in evaluating insecticides applied to field test plots for control
of the sugarbeet root maggot, Tetanops myopaeformis (Röder) (Diptera,
Otitidae); others (which he judged to be less useful) were loss of plant
stand, maggot counts, and yield. But he did not present data in support
of his statements. At this laboratory, maggot counts have been used
almost exclusively since 1962 to determine the direct effect of chemicals
on sugarbeet root maggots. However, in some tests the data also
included percentage of beets infested, percentage of beets scarred
(feeding damage), and damage rating. We present here an assessment
of these indices based on records at this laboratory for the period
