Changes in the degree and kind of infestation by storage insects and mites in imports into Great Britain since the EPPO Conference in Lisbon, 1967, are reviewed. There has been an overall fall in the percentage of infested cargoes from 33 % in 1967 to 23 % in 1973, and a corresponding fall in the incidence of occurrence of many species. The various changes in different classes of commodities, cereals, oilseeds, cocoa beans, etc., according to country of origin, are discussed in detail. The effects of containerisation and greater use of road transport, the growing problem of insecticide resistance in storage insects and mites and the significance of infestation in imports are discussed in relation to future developments in international trade.
