Toxic Effect of Some Plant Extracts on the Productivity of Wheat Granary Weevil, Sitophilus granarius (L.) (Coleoptera: Curculionidae)

Öz

In this study, leaf extracts of parsley, Petroselinum crispum; mint, Mentha piperita and thyme, Thymus vulgaris were used in the experiment to evaluate for their effect on productivity against granary weevil, Sitophilus granarius. All the extracts of test plants had effects on productivity to the granary weevil. The reduction of adults was highest in mint for granary weevil. Effects on productivity of leaf extracts are more or less same. Effect on productivity increased proportionally with the concentration of the plant extracts.

Buğday Biti, Sitophilus granarius (L.) (Coleoptera: Curculionidae)’un Verimliliği Üzerine Bazı Bitki Özütlerinin Toksik Etkisi

Öz

Bu çalışmada, maydanoz, Petroselinum crispum; nane, Mentha piperita ve kekik, Thymus vulgaris yaprak özütlerinin buğday biti, Sitophilus granarius’un verimliliği üzerine olan etkileri deneysel olarak değerlendirilmiştir. Deneme bitkilerinin bütün özütleri, buğday bitinin verimliliği üzerinde etkili olmuştur. Ergin birey azalması üzerinde nane, buğday biti üzerinde en yüksek etkiyi göstermiştir. Yaprak özütlerinin verimlilik üzerine etkisi çok ya da az benzerlik göstermiştir. Verimlilik üzerine olan etki, bitki özütlerinin konsantrasyonu ile orantısal olarak artmıştır

Anahtar Kelimeler

• Buğday biti, Sitophilus granarius, verimlilik, bitki özütü
