Sažetak
Essential oils from croatian aromatic plants: lavander, laurel, rosemary and thymus, and their single components had contact and fumigant activity to the major stored grain pests resistant to the phosphine-based fumigants applied so far. By gas-chromatography nine most significant oil components were determined: 1, 8-cineole, camphor, eugenol, linalool, carvacrol, thymol, borneol, bornyl-acetate, linalyl-acetate, and applied to the wheat and corn samples infested with seven pest species: S. granarius, S. oryzae, S. zeamais, R. dominica, T. castaneum, O. surinamensis, and C. ferrugineus. Laboratory analyses showed that highly susceptible primary species to the nine isolates were genus Sitophilus, followed by R. dominica, when treated with camphor, linalool, and 1, 8-cineole, and secondary species O. surinamensis when treated with 1, 8-cineole, camphor, linalool, and thymol. C. ferrugineus was susceptible in treatments with 1, 8-cineole, eugenol, camphor, and carvacrol. The exception was T. castaneum where application of plant preparations appeared to be insignificant. The most effective component and carrier of fumigant and contact toxicity was 1, 8-cineole, followed by camphor, eugenol, carvacrol, linalool, and thymol. Borneol, bornyl-acetate, and linalyl-acetate were less effective.
