NeemAzal, a commercial neem preparation with an azadirachtin content of 20%, was proven to be a growth retardant for the cockroach Periplaneta americana. As shown in the reduction of food consumption, the effect of NeemAzal, ingested as food, is predominantly to interpret as a phagodeterrent effect. The decreased ingestion of food results in a retardation of growth of the larvae and finally in a reduction of the reproductivity of the adults. The results suggest that a long‐term decimation of a population with a small fluctuation until its breakdown by intensive and permanent offering a NeemAzal‐containing bait may be possible.
