Metil öjenol ve diyatom toprağının depolanmış ürün zararlısı böceklere karşı tek başına ve birlikte etkisi

Tescilli bir diyatom toprağı Detech ve metil öjenolün Sitophilus granarius (L., 1758), Sitophilus zeamais Motschulsky, 1855 (Coleoptera: Curculionidae), Rhyzopertha dominica (Fabricius, 1792) (Coleoptera: Bostrychidae), Tribolium confusum Jaquelin Du Val, 1868 (Coleoptera: Tenebrionidae) erginlerine karşı Zirai Mücadele Merkez Araştırma Enstitüsü, Depolanmış Ürün Zararlıları Laboratuvarı (Ankara, Türkiye)’nda 2020 yılında test edilmiştir. Bu amaçla farklı dozlarda Detech (100, 250 ve 500 mg kg-1) ve metil öjenol (5, 10 ve 15 mg kg-1) kullanılmıştır. Böceklerin ölüm oranını belirlemek için farklı maruz kalma süreleri kullanılmıştır. Sinerjistik etkiyi belirlemek amacıyla, her iki ürünün de yarı dozları böcekler üzerinde çalışılmıştır. Diyatom toprağı Detech, R. dominica, S. zeamais, S. granarius ve T. confusum için en yüksek etkisi 500 mg kg-1 dozda, 28 günlük maruziyet süresinin sonunda sırasıyla %81, %29, %26 ve %18 ölüm oranı şeklinde gerçekleşmiştir. 15 mg kg-1’lık metil öjenol dozu, R. dominica için günlük maruziyetten sonra %100 ölüm oranı sağlamıştır. Her iki ürünün aynı anda kullanılması, üzerinde çalışılan böceklerde tam bir ölüm oranına ulaşmamıştır. Elde edilen veriler, Detech ve metil öjenol kullanımının depolanmış ürün zararlısı böcekler ile mücadelede ümit var sonuçlar verdiğini ortaya koymuştur.

Combined and individual effects of diatomaceous earth and methyl eugenol against stored products insect pests

The insecticidal activity of a proprietary diatomaceous earth, Detech, and methyl eugenol was tested with Sitophilus granarius (L., 1758), Sitophilus zeamais Motschulsky, 1855 (Coleoptera: Curculionidae), Rhyzopertha dominica (Fabricius, 1792) (Coleoptera: Bostrychidae), Tribolium confusum Jaquelin Du Val, 1868 (Coleoptera: Tenebrionidae) adults at Stored Products Pest Laboratory of Plant Protection Central Research Institute (Ankara, Turkey) in 2020. A range of doses of Detech (100, 250 and 500 mg kg-1) and methyl eugenol (5, 10 and 15 mg kg-1) were used. To determine insect mortality, at a range of times after treatment, and half-doses of both products were also studied in order to examine simultaneous use for synergistic effect. The greatest effect of Detech on R. dominica, S. zeamais, S. granarius and T. confusum was observed with 500 mg kg-1 giving 81, 29, 26 and 18% mortality 28 d after treatment (DAT), respectively. Methyl eugenol at 15 mg kg-1 gave complete mortality with R. dominica adults 3 DAT. Simultaneous application of both products did not give complete mortality in test insects. The data show that Detech and methyl eugenol are promising treatments for the control of insect pests of stored products.
