摘要:

AbstractGeneral accomplishments of a large co‐operative research program in the United States is reviewed. Examples of the developments of integrated pest control for the cotton and soybean agro‐ecosystems are given. The uses of simulation models are emphasized. Progress of integrated control in tropical countries is discus

摘要:

AbstractResearch in the various crop protection disciplines is carried out at the Central Norwegian Plant Protection Institute near Oslo: it includes studies on pesticide efficacy, problems of uptake, breakdown and residues. This agency is further in charge of the extension of practical knowledge and has a supervising capacity for the Plant Inspection Service.Some of the various problems which are of major concern for Norway are reviewed and ways for a proper integration of chemical and alternative methods studied.

摘要:

AbstractChanges 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.

摘要:

AbstractA survey of the occurrence of insecticide or fumigant resistant strains of stored‐product insects is given. Studies on the geographic distribution of insecticide‐resistant strains show that some resistances are localised and others almost universal. Cross‐resistance has been studied in few strains, but malathion resistance may involve resistance to other organo‐phosphorus compounds in at least 6 species. Although resistance to pyrethroids and juvenile hormone analogues is known, these compounds show promise for future use against storag

摘要:

AbstractThe paper describes some of the research currently in progress on insects, mites and fungi injurious to stored products, how problems are identified and how the results are put into practice. The research includes surveys in warehouses, farms, etc.; laboratory studies of biology under controlled conditions; storage of grain under various conditions; studies of the effects of contact insecticides, with special reference to resistance; fumigation, and the investigation of insect behaviour in relation to existing and novel control methods.
