Differences in resistance to Scutigerella immaculata (Newport) were shown among 5 broccoli cultivars in greenhouse studies. The cultivars, 'Crusader', 'Green Duke', and 'Bravo', showed a higher level of resistance to the garden symphylan than 'Waltham 29' and 'Spartan'. Crusader was most resistant and Spartan most susceptible. Results of field experiments showed similar differences in symphylan resistance among the cultivars and confirmed the results of the greenhouse studies.
