Sažetak
Insect infestation within stored product facilities is a major concern to the animal and human food industry. Insect infestation in storage systems can result in economic losses of up to 9 till 20 %. Furthermore, the presence of insects and their remains in grain and stored food may pose a health risk to humans and livestock. At present, pests in commercial storages are managed by a combination of different methods ranging from cleaning and cooling to treatment of the stored material with contact insecticides or fumigation. The available pesticides for treatment of grain and other stored products are decreasing owing in some cases to environmental and safety concerns among consumers and society, thus emphasising the need for alternative pest control methods. One of the potential methods is the use of ozone. Although the mechanism of action of ozone on insects is not completely known, the insect´s respiratory system is a likely target. The main goal of this investigation was to determine efficacy of ozone in suppression of different insect pests. The investigation have been conducted on six different insect species which were in different growing stages (adults: Blatta lateralis, Blaptica dubia, Gryllus campestris ; larvae: Pachnoda sinuata flaviventris, Tenebrio molitor i Zophobas morio). The results shown the harmful effects of ozone on insects. The maximum efficiency of ozonation was found in insects where adults have been treated and a very small and no efficacy was found in the treated larvae. Ozone efficiency increases with increasing ozone exposure. The results of this investigation suggest that ozone has the potential to become a realistic choice in suppressing harmful insects in storage systems for human and animal nutrition, either alone or as a complement to other methods.
