Abstract
The German cockroach, Blattella germanica (L.), control program described here was designed to reduce the impact of resistance, poor sanitation, and ineffective application technique. The components of the program were 1) surveys of the cockroach infestation level, and the attitudes of the target audience; 2) an insecticide resistance profile of the pest population; 3) an educational program; 4) a training program for management and pest control personnel; 5) specific control strategies; and 6) an evaluation of the program. The control program was field tested in Norfolk, Va., with the Norfolk Redevelopment and Housing Authority. Among the evidence for the decline in serious cockroach problems was the amount of money spent by residents for cockroach control. In 1982, residents spent an average of 68.00; this decreased to 44.00 in 1983. In 1982 the majority (57%) of residents mentioned insecticides as the best cockroach-control method, and only 16% mentioned cleanliness. In 1983, only 38% of residents mentioned insecticides as the best control method; 28% thought cleanliness was the best method. The data from the profile of insecticide resistance indicated that the most acceptable and effective insecticide would be an organophosphate.
