Plank and Winters (1949) reported that in Puerto Rico the species of Orthoptera most injurious under greenhouse conditions was _Periplaneta americana_. Large nymphs destroyed 25 to 30 percent of freshly planted seed of _Cinchona pubescens_. In Hawaii the host plants of _P. americana_ are blossoms of _Canna_ and _Tribulus_, and the host plants of _Periplaneta australasiae_ are _Pritchardia_ and _Sida_ (Zimmerman, 1948). On St. Kitts, B.W.I., young cotton plants were severely attacked by _P. australasiae_; this caused loss of the stand on a considerable area and necessitated replanting (Ballou, 1916). _P. australasiae_ was reported damaging the _Polystichum aristatum_ Presl [=_Lastrea aristata variegata_] in a greenhouse (Thilow and Riley, 1891). Laing (1946; British Museum [Natural History], 1951) stated that _P. australasiae_ abounds in greenhouses and forcing pits where it may do considerable damage to the plants. _Periplaneta fuliginosa_ is also troublesome in greenhouses because of its tendency to feed on seedlings and succulent plants (Dodge and Rickett, 1943). _Ectobius lapponicus_ has been observed feeding in galleries in the thick skin of young aspen in 25 percent of the trees examined (Stark _in_ Bei-Bienko, 1950). The aquatic cockroach _Epilampra abdomen nigrum_ fed on the leaves of _Jussiaea natans_ in an aquarium (Crowell, 1946). _Ischnoptera deropeltiformis_ has been taken while it was feeding on a fleshy fungus (_Agaricus_ sp.) in dense woods in Indiana (Blatchley, 1920). _Diploptera punctata_, the cypress roach or beetle roach, has been found in Hawaii feeding on ripening mangoes and papayas, oranges on the tree, and the outer covering of the pods of _Acacia farnesiana_ (Bridwell and Swezey, 1915). Pemberton (1934) stated that _D. punctata_ "disfigures our cypress trees by eating the bark from the young branches, often giving them a dead appearance over much of their leaf area." Fullaway and Krauss (1945) added, "This injury [to cypress] is so severe that sometimes areas of leaves die and turn brown. The Japanese cedar, ironwood, citrus and algaroba (kiawe) trees are attacked in a similar manner." Similar injury to cypress was described by Hebard (1922). In addition to girdling _Cupressus_, _D. punctata_ injures _Cryptomeria_ in the same fashion and also attacks algaroba, lime, and other plants (Pemberton and Williams, 1938). Zimmerman (1948) cited the following host plants for _D. punctata_ in Hawaii: "_Cupressus macrocarpa_, _Casuarina_, _Cryptomeria_, _Citrus_, geraniums, _Acacia farnesiana_ pods, mango fruits, orange fruits, papaya fruits."
