Chemical control of stored product insects with fumigants and residual treatments

Integrated pest management (IPM) programs that eliminate infestations and p revent economic damage in raw commodities, food storage facilities, and mil ling and processing plants typically involve chemicals. They are preferred because they are often the cheapest and most efficient strategies available . When evaluating pesticides, it is important to recognize the biological a nd environmental factors that can affect pesticide efficacy so the insectic ide can be effectively used in control programs. We illustrate these concep ts with data from research studies with cyfluthrin, a pyrethroid insecticid e used as a residual surface treatment, and with data from developmental re search with new fumigants. These chemical pesticides and others like them c ould have specific applications and strategies in an IPM program for post h arvest pests well into the 21st Century. Published by Elsevier Science Ltd.
