Abstract: In laboratory experiments the suitability of six fruits of indigenous trees and shrubs, which are also available in the field during wintertime, was tested as food and development medium for ten stored products insects. Undamaged fruits of oaks (Quercus robur and Qu. borealis), horse chestnuts (Aesculus bippocastanum) and beech (Fagus sylvatica) could not be attacked by any of the tested beetles and moths. Damaged or peeled fruits of Qu. robur and F. sylvatica, however, served as development medium for seven pests. The least fitted substrates were hipberries (Rosa canina) and acorns of Qu. borealis. The number of adults emerging from the wild fruits was normally lower than that from control mediums. An exception was found in Sitophilus granarius developing in acorns of Qu. robur. Oryzaephilus surinamensis, Stegobium paniceum, Ephestia kuehniella and Plodia interpunctella had the broadest food spectrum with five fruits each. The beechnut offered the best possibilities for development. Only those insects living inside of seeds (Sitophilus granarius, S. oryzae and Sitotroga cerealella) were not able to form a new generation in this fruit. The influence upon the length of the development period was different according to fruit and pest species. The slightest difference, compared with a normal medium (rolled oat, wheat bran and glycerine) was found in the mediterraneum flour moth (E. kuehniella). As stored products insects can be found relatively often in outdoor biotopes, especially in the surrounding of silos or stores, it can not be excluded that fruits of wild plants may offer-at least for a certain period-a possibility for survival. Thus they may act from time to time as a source of infestation.
