    In The Netherlands, a computerized advisory system (called Gaby) for integrated pest management (IPM) in apple has been developed to support the decision making of individual fruit growers. Gaby provides clear monitoring recommendations when this is appropriate for a particular pest in (a defined area of) the orchard by using information concerning orchard characteristics, phenology of pests, previous field observations and insecticide applications. It recommends treatments only if control thresholds are exceeded, while indicating the most appropriate type and concentration of insecticide and the optimal time for control. Advice is accompanied by information on pest insects, damage symptoms, natural enemies, control thresholds, side-effects of insecticides and integrated fruit production guidelines. Gaby contains actual knowledge on the IPM of all major pests in Dutch apple orchards. In this paper we give a working description of Gaby and describe the separate decision schemes for each pest. These schemes reflect the present status of IPM in Dutch apple orchards.
