Note 6 — XII. ARTHROPODA

Page 11 of Marlatt (1902) has been cited erroneously so many times in support of host records for T. hagenowii and Evania appendigaster that we are quoting the pertinent section below. In the section preceding the quoted material Marlatt discusses the American, Australian, oriental, and German cockroaches. There is nothing in the paper to connect any of these cockroaches specifically with the parasites mentioned below:

NATURAL ENEMIES AND PARASITES

"In Europe the egg capsules of the cockroach are often parasitized by an ichneumon fly (Evania appendigaster). This insect has become widely distributed over the world following its host insect, and has been redescribed under a great many different names. It was found in Cuba as early as 1829, and has been several times collected in the United States. Unfortunately, its usefulness as a means of keeping the roach in check by destroying the egg capsules is greatly impaired by the occurrence of another ichneumon fly (Entedon hagenowi), which is parasitic upon the first. This is also a European species which has been brought over with its host parasite. If the true egg capsule parasite of the roach could have been introduced into this country without this secondary parasite, its usefulness would doubtless have been very much greater. The secondary parasite, however, seems to have been introduced early, and has been found in Cuba and Florida, and probably occurs as widely as its host and prevents the latter from multiplying very greatly."
