This publication reports on the results of a Co-ordinated Research Project completed by the FAO and IAEA on the systematic screening and laboratory and field testing of known and new candidate attractant odours for use in the suppression or monitoring of tsetse populations and in barrier systems.

Proceedings of a symposium jointly organized by the IAEA and FAO, Vienna, 19–23 October 1992. In the past decade significant progress has been made in overcoming many of the difficulties of biologically based methods of pest management. Particularly important are the advances made in the field of molecular technology and biotechnology. Presentations in this symposium focus on advances and trends in insect control and eradication, genetic engineering and molecular biology, insect genetics, operational SIT programmes, F1 sterility and behaviour, biocontrol, tsetse fly R&D, and quarantine.
Contents: Genetic engineering and molecular biology; Genetics; Operational programmes; F1 sterility and insect behaviour; Biocontrol; Research and development on the tsetse fly; Quarantine.

Proceedings of the final research co-ordination meeting organized by the Joint FAO/IAEA Division of Nuclear Techniques in Food and Agriculture, Phoenix, Arizona, 9–13 September 1991. Genetic control of lepidopterous pests includes the environmentally benign use of the sterile insect technique as well as the use of inherited sterility, which is especially pronounced in the first filial (F1) generation following the exposure of the parents to substerilizing doses of ionizing radiation. In the case of inherited sterility, the F1 generation is reared in the field, thereby reducing costs. Some lepidopterous species can be mass reared in factories, stockpiled in diapause, irradiated and activated for release in synchrony with the wild population. This method has been highly successful since 1968 in protecting 0.5 million hectares of cotton in the San Joaquin Valley of California from the pink bollworm. This report presents information mainly on the inital phases in the development of the use of inherited sterility to manage populations of the corn earworm, codling moth, Asian corn borer, European corn borer, diamondback moth, cotton leafworm, fall army worm, tropical army worm, gypsy moth, pink bollworm and wild mulberry silkworm.
