Sažetak
Essential oils and plant dust of four Croatian aromatic plants (Lavandula officinalis Ch., Laurus nobilis L., Rosmarinus officinalis L., Thymus vulgaris L.), were tested for insecticidal activity against lesser grain borer Rhyzopertha dominica F. on mercantile and seed wheat under laboratory and storage conditions. The insecticidal effect was observed over the exposure period up to 100% mortality of adults. The efficacy of the plant material was compared to the control with no treatment. Doses of essential oils and plant dust were recalculated on 5 kg wheat sample, as follows, 3, 75 ml/sample of oils, and 37, 5 dag/sample of dust. In general, all essential oils exhibited strong insecticidal effect (100% mortality of adults after 24h), with L. nobilis proved most effective in dust form (100% mortality of adults after 7 to 10 days of exposure) under storage conditions. In the control samples mortality of adults was not recorded. Over the five months period, damage on wheat was found to be 30%, while insect population increased up to 190%. No changes in quality of mercantile wheat flour, its colour and flavour were recorded over the plant product treatment, however, each sample retained the scent of the plants tested. On seed wheat, no negative effect on germination and energy of germination was recorded. These aromatic plant products proved to be partial substitutes for synthetic insecticides if applied to smaller stocks of stored wheat, and in order to reduce contamination of food and environment.
