The development of the Asian cockroach, Blattella asahinai Mizukubo, was studied under laboratory conditions. Immature development and adult longevity were 67.8 and 103.5 d for females and 65.7 and 48.5 d for males. Females produced an average of 3.7 oothecae, 64.6% of which were viable. Viable oothecae contained an average of 37.5 eggs with an 88% rate of hatch. Females required 13 dafter eclosion to produce the first ootheca and 7.9 d between dropping one ootheca and producing the next. Viable oothecae were incubated an average of 19.2 d. Nonviable oothecae were either dropped within 4 d or carried for a period similar to the incubation period of viable oothecae. The estimated lifetime reproductive potential of female Asian cockroaches was 79.6 hatched eggs. This estimate is similar to that of another outdoor species, Blattella vaga Hebard, but approximately one half that of the closely related German cockroach, B. germanica (L.), under similar conditions. Tests in the field and laboratory indicated that chemical control is feasible with application of residual pesticides to lawns and low vegetation where Asian cockroaches are found.
