Cockroach, England? (Ealand, 1915): Cockroaches may carry the hypopial stage of the cheese mite.
CONTROL OF MITES IN COCKROACH COLONIES
Fisk (1951) eliminated the mites [possibly Pimeliaphilus podapolipophagus (Baker et al., 1956)] in his cockroach colony by using a 5-percent spray and a 5-percent dust of p-chlorophenyl, p-chlorobenzene sulfonate. The exterior of the cockroach containers were sprayed with the solution and the interior, including the insects, were dusted. Within a month the mites had disappeared and the vigor of the cockroach colony improved. Piquett and Fales (1952) used flowers of sulfur and general sanitary procedures for eliminating the mites in laboratory colonies of Blatta orientalis; they cleaned the dishes every few days and applied grease around the edges of the containers to prevent new mite invasions. Qadri (1938) employed similar control measures.
Class CHILOPODA
Large centipedes which entered houses in India probably sought out cockroaches (Maxwell-Lefroy, 1909). In Puerto Rico, centipedes entered homes to which they were attracted by cockroaches (Seín, 1923). In Hawaii, centipedes preyed on insects generally but especially on cockroaches (Bryan, 1915). Sonan (1924) reported that in Formosa and Okinawa Islands a species of centipede 5 to 6 inches long comes into the houses and devours both adults and nymphs of Periplaneta americana or P. australasiae. Zimmerman (1948) found P. australasiae breeding by scores in rock piles in Hawaii accompanied by large numbers of Scolopendra and large spiders that probably preyed upon the cockroaches.
