Population development of Scutigerella immaculata (Newport), in laboratory and greenhouse cultures

Creator:: Ramsey, Henry Lee
Abstract:: Population development of the symphylan, Scutigerella immaculata (Newport), was studied in laboratory cultures. Also symphylan injury to greenhouse plants was investigated. Plastic polyethylene containers partly filled with damp ground hemlock bark were used to culture symphylan in the laboratory. Fresh lettuce food was supplied to the cultures weekly. Factors which...
