COCKROACHES ASSOCIATED WITH SHIPS
In the following list we include some previously unpublished data on cockroaches that were recovered from ships at the Miami, Fla., Quarantine Station for the periods November 1945 through May 1946; May, June, August, and September 1950; and 17 July 1957 (Porter, personal communication, 1958). These data were lumped, without breakdown to species, under the entry Orthoptera in Porter (1958).
Certain of the species listed below occur only accidentally on shipboard and will probably never establish breeding colonies on ships or become pests on shipboard or elsewhere; some were merely passengers between one land-based colony and another. Others, the truly domiciliary pests, are as likely to be pests on shipboard as they are in land-based structures.
Blaberus discoidalis
Hispaniola.—On board ship (Rehn and Hebard, 1927).
Blatta orientalis
U.S.A.—At Port of New York (Richardson, 1947).
Blattella germanica
At sea?—In ships casks (Chamisso, 1829).
U.S.A.—Port of New York (Williams, 1931; Richardson, 1947). San Francisco (Simanton, 1946). At Miami, 7,852 live specimens recovered from ships (Porter, personal communication, 1958). Most numerous species on ships (Rice, 1925).
Epilampra maya
At sea.—One male and one female found dead on S.S. Tenadores (Hebard, 1917).
Epilampra sp.
Florida.—One dead specimen, Miami (Porter, personal communication, 1958).
Ischnoptera sp.
Florida.—Five live and one dead specimen, Miami (Porter, personal communication, 1958).
Latiblattella sp.
At sea.—One female alive in hold of S.S. Tenadores (Hebard, 1917).
Leucophaea maderae
Brought from West Africa to West Indies and Brazil by slave ships (Rehn, 1945).
Nauphoeta cinerea
Widely disseminated by sailing ships (Rehn, 1945).
Neoblattella fratercula
At sea.—Two females found dead on S.S. Tenadores (Hebard, 1917).
Neoblattella fraterna
At sea.—One male found dead in hold of S.S. Tenadores (Hebard, 1917).
Neoblattella nahua
At sea.—One female dead in hold of S.S. Tenadores (Hebard, 1917).
Neoblattella sp.
Florida.—Five dead specimens recovered from ships, Miami (Porter, personal communication, 1958).
Neostylopyga rhombifolia
Widely distributed by sailing ships (Rehn, 1945).
England.—Captured on a sugar vessel from Java (Lucas, 1920).
Nyctibora noctivaga
At sea.—One male and one female nymph found dead on S. S. Tenadores (Hebard, 1917).
Nyctibora sp.
Florida.—Two dead specimens recovered from ships at Miami (Porter, personal communication, 1958).
Oxyhaloa buprestoides
Spread from Africa to New World by ships (Rehn and Hebard, 1927; Rehn, 1945).
Panchlora nivea
At sea.—One female dead in hold of S.S. Tenadores (Hebard, 1917).
Florida.—Fifteen dead specimens taken from ships, Miami (Porter, personal communication, 1958).
From the numerous records of this species as an adventive taken on bananas (p. [150]), it may be presumed to be a frequent traveler on banana boats.
Periplaneta americana
At sea.—Lewis (1836). Hebard (1933a) stated that this is "often a serious pest on the smaller ships sailing the South Seas."
U.S.A.—San Francisco (Simanton, 1946). Port of New York (Richardson, 1947). At Miami, 62 live and 123 dead specimens (Porter, personal communication, 1958).
Periplaneta australasiae
Migrated from West Africa to America in slave ships (Rehn, 1945).
Pycnoscelus surinamensis
Probably in part reached the New World by way of Africa in slave ships (Rehn, 1945).
Supella supellectilium
Reached America from West Africa by slave ship (Rehn, 1945).
Xestoblatta festae
At sea.—One female found dead in hold of S.S. Tenadores (Hebard, 1917).
