Abstract:

 

In this study, insecticidal effects of 13 Entomopathogenic fungi (EPF) isolates recovered from Adana Province [Nine Fusarium spp., three Beauveria bassiana (B. bassiana) and one Purpureocillium lilacinum (P. Lilacinum) isolates] was tested against the adults of Sitophilus oryzae  (S. oryzae) (L.) (Coleoptera: Curculionidae) under controlled conditions at 25±2 °C. Single (1x107conidia mL-1) and multiple-dose (1x105, 1x106, 1x107, 1x108 ve 1x109 conidia mL-1) experiments were conducted and mortality rates were recorded on 5th, 7th, 9th and 14th days after treatment (DAT). P. lilacinum-224, B. bassiana-310 and Fusarium sp.-339 were the most efficient isolates in single-dose experiments and included in the multiple-dose bioassay. All the isolates caused high mortality (%100) at both 1x108 and 1x109 doses 14th DAT in the multiple-dose experiment. The calculated LC50 and LC95 values of the selected isolates were ranged between 889 and 16.231 conidia adult-1. The results showed that all isolates tested in multiple-dose experiments have a great potential for the control of the adults of S. oryzae. However, further studies are needed to reveal their efficacy under storage conditions.

 

Bu çalışmada, Adana ilinden elde edilen 13 Entomopatojen fungus (EPF) izolatının [dokuz Fusarium spp., üç Beauveria bassiana (B. bassiana) ve bir Purpureocillium lilacinum (P. Lilacinum)] insektisit etkisi Sitophilus oryzae (S. oryzae) (L.) (Coleoptera: Curculionidae) erginlerine karşı kontrollü koşullar altında 25±2 oC'de test edilmiştir. Tekli (1x107conidia mL-1) ve çoklu doz (1x105, 1x106, 1x107, 1x108 ve 1x109 conidia mL-1) denemeleri yapılmış ve ölüm oranları uygulamadan sonraki 5., 7., 9. ve 14. günlerde kaydedilmiştir. Tekli doz denemelerinde en etkili izolatlar olarak P. lilacinum-224, B. bassiana -310 ve Fusarium sp.-339 izolatları olmuştur ve bu izolatlar çoklu doz denemelerine dahil edilmişlerdir. Tüm izolatlar, çoklu doz denemelerinde 1x108 ve 1x109 uygulama dozunda uygulamadan sonraki 14. günde yüksek ölüm oranı (% 100) meydana getirmişlerdir. Seçilen izolatların hesaplanan LC50 ve LC95 değerleri 889 ve 16.231 conidia ergin-1 arasında değişmiştir. Sonuçlar, çoklu doz denemelerinde test edilen tüm izolatların, S. oryzae erginlerinin kontrolünde büyük bir potansiyele sahip olduğunu göstermiştir. Bununla beraber, bu izolatların depo koşulları altında etkinliklerini belirlenmesi için daha fazla çalışmaya ihtiyaç vardır.
