Assessment of the influence of magnetic fields on aspects of the biology of the adult Mediterranean flour moth Ephestia kuehniella Zeller, 1879 (Lepidoptera: Pyralidae)

Abstract

All living systems are under the influence of magnetic fields (MFs) from various sources. In this study, experiments were performed to investigate the effect of MFs from a DC power supply on the longevity of adults, fecundity and daily egg laying pattern of female E. kuehniella. Adults of E. kuehniella (24 h old) were exposed to power supply generating MFs of different levels (0, 1.5, 3, 5, 7.5 and 10 mT) at 50 Hz for 24 h exposure time. Mortality increased with increasing MFs level and complete mortality was achieved at the level of 10 mT. Adult viability was highest in control (92%). Pest longevity was significantly reduced with increasing level of MFs (P<0.05). There was no significant difference in the longevity of males and females (P˃0.05). Exposing adults to increasing level of MFs significantly influenced daily egg laying patterns and fecundity of magnetized females. Larval emergence from these eggs was completely prevented at highest level of MFs. The LD50 and LD99 values of MFs against adult stages of E. kuehniella were measured as 5.23 mT and 12.81 mT, respectively. According to these results, 10 mT MFs for 24 h is sufficient to control adult survival and production of progeny in this pest

Akdeniz un güvesi Ephestia kuehniella Zeller 1879 (Lepidoptera: Pyralidae)'nın ergin biyolojisi üzerine manyetik alanın etkisinin belirlenmesi

Öz

Tüm canlı sistemler çeşitli kaynaklardan gelen manyetik alanın etkisi altındadır. Bu çalışmada deneyler ergin ömür uzunluğu, yumurta açılımı ve E. kuehniella dişilerinin günlük yumurta verimi üzerine güç kaynağından gelen DC manyetik alanın etkisini araştırmak için yapılmıştır. E. kuehniella erginleri (24 saatlik) farklı seviyelerde (0, 1.5, 3, 5, 7.5 ve 10 mT) 50 Hz’de 24 saat süreyle manyetik alan üreten bir güç kaynağına maruz bırakılmıştır. Artan manyetik alanda ölüm oranları giderek artmış ve 10 mT’da erginlerin tamamı ölmüştür. Canlı ergin oranı % 92 ile en yüksek kontrolde elde edilmiştir. Zararlının ömür uzunluğu artan manyetik alanla önemli ölçüde azalmıştır (P<0.05). Erkek ve dişi bireyler arasında ömür uzunluğu açısından fark bulunmamaktadır (P˃0.05). Artan manyetik alana maruz kalan dişilerin günlük yumurta verimi ve bu yumurtaların açılımları önemli ölçüde etkilenmiştir. Bu yumurtalardan larva çıkışı en yüksek dozda tamamen engellenmiştir. E. kuehniella erginlerine karşı manyetik alanın LD50 ve LD99 değerleri sırasıyla 5.23 mT ve 12.81 mT olarak bulunmuştur. Bu sonuçlara gore, 24 saat süreyle 10 mT manyetik alan uygulaması bu zararlının canlılığını ve yumurta verimini kontrol etmek için yeterlidir
