Agricultural and environmental importance of Cean-Bolduț antierosional forest belts in Transylvania.

Abstract

The paper is related to plant-pest-entomophag interactions in cerea agroecosystem of Agricultural Research-Development Station Turda, in Transylvania. Under the conditions of actual agroecological changes, yielded by climatic warming and dryness and new technological and economical conditions of zone agricultural exploitations, the research points out the extension risk of cereal pests attack with an increasing potential and the importance of the elaboration of integrated control strategy (ICS). The attack diminishing recommended methods of the ICS are agro-technical methods; pests, diseases, weeds integrated control; insecticides treatments; conservation and use of entomophagous limiters. The natural predators play an important role in decreasing the pest abundance in Transylvania. The well-known systematic groups of enthomophagous predators: Aranea; Dermaptera; Thysanoptera (Aeolothripidae); Heteroptera (Nabidae); Coleoptera (Carabidae, Cicindelidae, Staphylinidae, Sylphidae, Coccinellidae, Cantharidae, Malachiidae); Diptera (Syrphidae, Empididae); Hymenoptera (Formicidae); Neuroptera (Chrysopidae) were represented in the structure of arthropod fauna. The abundance and the activity quality of entomophagous populations were higher in the system of crops with protective forest belts, existing since 1952, in the Cean-Bolduţ farm of A.R.D.S. iin Turda. Therefore, on the farm with protective forestry belts and with field marginal herbs shelters, favorable for the development of entomophagous arthropod fauna, a real natural  ntomocenotic equilibrium and a natural biological control of important pests were registered. By comparison it is necessary to apply the insecticide treatments on the cereal agroecosystem in open field areas, because the development of pest population exceeds the adjusting capacity of entomophagous arthropod fauna.
