In the reports of damage to plants by cockroaches, _Pycnoscelus surinamensis_ has been implicated most often. This species is undoubtedly one of the economically most important cockroaches, being the vector of the chicken eyeworm as well as feeding on plants. In addition to the few reports of damage caused by this species that have already been mentioned, _P. surinamensis_ has been reported to be very destructive in New Orleans to palms and ferns, attacking large alsophilas avidly, eating out the hearts (Anonymous, 1893). Zappe (1918) in Connecticut reported damage in a greenhouse to roses valued, at that time, at several hundred dollars; _P. surinamensis_ had girdled the rose bushes, done much damage to Easter lilies, and in another greenhouse had eaten the bark from the stems of poinsettias. In Germany this species bit off the tips of the aerial roots and ate the petals of orchids (Zacher, 1920). Lucas (1923) reported damage to cucumber plants in a greenhouse in Surrey. Damage by _P. surinamensis_ to the stems of rose bushes has been reported in Rhode Island and Pennsylvania; the canes were attacked both under and above ground (Caudell, 1925). Doucette and Smith (1926) reported a heavy infestation of _P. surinamensis_ in a range of greenhouses in Philadelphia: "The roaches were present literally by the millions.... Although the roaches had been observed in cabinets and trash barrels for several months, it was not until the manager had occasion to go through the house one evening that he discovered that roaches were the cause of the troubles previously attributed to soil condition, watering, fungus, and other agencies.... About 30,000 to 35,000 rose plants from a total of 200,000 in the three more heavily infested houses were so badly injured by the gnawing off of the bark, young buds, and shoots of the main stems, that they were not in condition to be kept in the beds for another season."
