Pests living in the soil cause great damage to horticultural crops every year, particularly those managed by organic farming methods. The most damaging pests are larvae of the genera Melolontha. The purpose of the research was to develop and evaluate the efficacy of a variety of non-chemical methods to reduce the damage caused by the grubs on organic strawberry plantations. The used mechanical methods included soil ploughing and tilling, and hand picking grubs from damaged plants during inspection or manual weed control. The used physical methods were: soil and plants mulching with white agro-textile to limit egg laying and light traps to attract and collect adults. The results indicate even though each method alone is not sufficient to effectively protect organic strawberry crops against Melolontha spp grubs, their integrated use could drastically reduce the population pressure of the insect on the crop and thus increase also the efficacy of other methods, e.g. based on biocontrol mechanisms.
