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

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

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

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
