Resumo: | Combined production of broilers and fruit trees is a subject often discussed in organic fruit  production in Denmark. Very little research has been carried out on this type of production  system. In organic production in Denmark, nearly no pesticides are allowed, so the need  for alternative pest control is large. Apple sawfly (Hoplocampa testudinea) and pear midge  (Contarinia pyrivora) cause big crop losses in apples and pears respectively, in unsprayed  organic fruit production. Both insects infest fruitlets and cause these to drop prematurely  after which the pests pupate in the topsoil. In the present experiment a research orchard  with the varieties ‘Discovery’ and ‘Conference’ were used as outdoor area for broilers to  minimise the population of sawflies and pear midges, and to reduce the need for weeding  and manuring. The trees were kept unsprayed. Fruit yield and fruit quality were assessed  at harvest. White sticky traps were placed in the test area in order to measure the  occurrence of sawfly over time. The infestation of pear midge was investigated counting  the infested fruitlets in clusters on trees at the centre of the plots. The catch of apple  sawflies was reduced in the combined apple and broiler production, but no significant  effect on the yield or the fruit quality was seen. Experiences from on-farm research show  that combining fruit and egg-production is one way to reduce the problem with apple  sawfly, but poultry alone is not a sufficient way of controlling sawflies. The welfare and  health of the broilers were excellent under fruit trees.
