The problem of a replacement for dieldrin

For more than 30 years the main strategy for preventive control of the desert locust Schistocerca gregaria (Forskal, 1775) has been based on the correct use of an organochlorine, dieldrin. This insecticide was used because it was effective at very low doses for locust control, activated both by contact and ingestion, had a long persistence, a long storage life and was relatively inexpensive.
