Öz: Çalışmada kullanılan depo zararlılarından Acanthoscelides obtectus Say (Coleoptera: Chrysomelidae) fasulyede önemli derecede ekonomik kayba neden olmaktadır. Diğer depo zararlısı Oryzaephilus surinamensis (L.) (Coleoptera: Silvanidae) depolanmış ürünlerin başlıca zararlılarındandır. Bahsedilen iki tür de dünya genelinde yayılış göstermektedir. Bu zararlılarla mücadelede piretriod bazlı insektisitlerin farklı formülasyonlarının etkili olduğu bilinmektedir. Ayrıca bu kimyasalların düşük dozlarının zararlılar üzerindeki etkilerinin ortaya çıkartılması oldukça önemlidir. Bu amaçla bu çalışmada da laboratuvar koşullarında uzun zaman insektisite maruz kalmayan depo zararlıları (A. obtectus ve O. surinamensis) üzerinde Deltamethrin etkili insektisitin letal etkileri ortaya çıkartılmış ve LC30, LC40 ve LC50 değerleri belirlenmiştir. Çalışma genelinden elde edilen verilere göre denemede kullanılan insektisitin A. obtectus ve O. surinamensis mücadelesinde kullanılabileceği, ancak düşük dozlarının zararlılar üzerindeki etkilerinin belirlenmesinin de önemli olduğu sonucuna varılmıştır. Elde edilen verilerin uygulanan insektisitin subletal dozlarının zararlılar üzerindeki etki çalışmalarına destek sağlayacağı düşünülmektedir. Ayrıca uygulanacak dozlarla ilgili elde edilen bilgiler bahsi geçen türlerin yaşam çizelgeleri üzerindeki etkileri hakkında da kaynak teşkil edecektir.

Lethal Effects of Delthamethrin on Dried Bean Beetle Acanthoscelides obtectus Say (Coleoptera: Chrysomelidae) and Saw-toothed Grain Beetle Oryzaephilus surinamensis L. (Coleoptera: Silvanidae)

Öz

Abstract: Acanthoscelides obtectus Say (Coleoptera: Chrysomelidae) used in the study causes significant economic losses in beans. 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.
