Abstract

The garden symphylan (Scutigerella immaculata Newport) population of a field of table beets, Beta vulgaris L., in northwestern Oregon, was studied. The number of symphylans from the samples ranged from 110 to 1131 per cubic foot with an average of 557. Several laboratory tests were conducted to study garden symphylan population increases in soil types treated differently. It was found that garden symphylans reproduce well in soil types such as Felida, Salkum, and Melbourne. Manure added to these soils increases their porosity, probably supplies additional foodstuff, and consequently provides the best rearing medium.
