Matching control options to a pest complex: the integrated pest management of aphids in sequentially-planted crops of outdoor lettuce

Sequentially planted short-season vegetable crops grown in temperate climates offer the opportunity to use known variations in pest phenology through the season to develop a strategic way of matching control options on different plantings to predicted levels of pest risk. To test this approach in the UK, five field experiments were done over two years to test integrated pest management (IPM) programmes for four aphid pest species ( Nasonovia ribisnigri, Macrosiphum euphorbiae, Pemphigus bursarius and Myzus persicae) on outdoor lettuce crops. Crops were planted to coincide with different periods of forecast aphid risk. The results suggested that acceptable levels of aphid control could be achieved, provided a full range of treatment options (resistant cultivars, selective insecticides, biocontrol agents and validated pest forecasts) could be utilised. Commercial and technical constraints to the commercial adoption of this approach are discussed.

The development and management of an in vitro fertilisation unit.

In this brief presentation on the development, management and results of treatment in the first year of operation of the Fertility Unit at the Humana Hospital Wellington, we have tried to give an overview of how we believe a large regional reproductive medicine centre could be managed and developed within the National Health Service. Such a centre should provide a comprehensive range of fertility treatment, preferably every day of the week. It would include the full range of treatment options including induction of ovulation, artificial insemination, tubal microsurgery, as well as IVF and the T-SET methods. The advantage to the patients would be considerable and it may even be possible to make financial savings compared with those expenses incurred by the unstructured infertility services offered at present.
