The other storage pest, Oryzaephilus surinamensis (L.) (Coleoptera: Silvanidae), is a major pest of stored products. Both species mentioned are distributed worldwide. It is known that different formulations of pyrethroid-based insecticides are effective in controlling these pests. In addition, it is very important to reveal the effects of sublethal doses of these chemicals on pests. For this purpose, in this study, lethal effects of Deltamethrin effective insecticide on storage pests (A. obtectus and O. surinamensis) that have not been exposed to insecticide for a long time under laboratory conditions were revealed and LC30, LC40 and LC50 values were determined. According to the data obtained from the study in general, it was concluded that the insecticide used in the trial can be used in the control of A. obtectus and O. surinamensis, but that it is also important to determine the effects of low doses on pests. It is thought that the obtained data will support the studies on the effects of sublethal doses of the applied insecticide on pests. In addition, the information obtained about the doses to be applied will also constitute a source for the effects on the life cycles of the mentioned species.}, number={1}, publisher={Yozgat Bozok Üniversitesi}
