Studies were conducted on the mechanisms contributing to
resistance in broccoli, Brassica oleracea italica, to the garden
symphylan, Scutigerella immaculata (Newport). Differences in
resistance to symphylan injury were shown between five selected
broccoli cultivars. The hybrid cultivars, Crusader, Green Duke
and Bravo, showed a higher level of resistance to symphylans...
A study was conducted of the response of the garden symphylan,
Scutigerella immaculata (Newport), to naturally occurring chemicals.
Results of olfactometer studies with plant odors were inconclusive
because air currents in one olfactometer and the shape of another had
undesirable effects on symphylan behavior.
Non-random distributions of symphylans in chambers...
