Sažetak
This research has been carried out to investigate insecticidal activity of some Mediterranean aromatic plants in Croatia against stored product insects, in order to use them as ecological and natural insecticides. Mercantile and seed wheat was infested by adults of Rhyzopertha dominica and Sitophilus granarius which were treated by Lavandula officinalis, Laurus nobilis, Rosmarinus officinalis and Thymus vulgaris with application in two forms: essential oils and plant powder. The insecticidal effect was observed by exposition of time up to 100% mortality of adults. The efficiency of the plant materials was compared to chemical insecticide based on DDVP, and to control with no treatment. Complete research was carried out under laboratory and storage conditions during winter and summer season. Against R. dominica all essential oils had strong insecticidal effect, while in powder form L. nobilis was the most effective. The best efficacy against S. granarius showed T. vulgaris essential oils, while L. officinalis and L. nobilis had very good results in powder form. After completed analysis, the quality of mercantile and seed wheat was tested. Mercantile wheat was assayed by using ekstenzograph, farinograph and amilograph determining the quality of flour and it was not changed. The quality of seed wheat was tested by analyses of energy of germination and germination itself. No significant statistical differences were founded among the control without application and treatments in both characteristics. In general, all investigated aromatic plants (L. officinalis, L. nobilis, R. officinalis and T. vulgaris) in forms of essential oils and plant powder showed insecticidal activity against R. dominica and S. granarius on mercantile and seed wheat under laboratory and storage conditions. In praxis, synthetic insecticides can be partly replaced by these plant products for less quantity of stored wheat and decrease contamination of food and environment.
