Effects of Continuous Ligth and Darkness on the Total Lipid Amounts of Achroia grisella (Lepidoptera: Pyralidae)’s Different Ages Adults

Öz

Achroia grisella is a harmful species for combs and it’s larvae are known as causing serious damages in beekeeping. It is important to know the biological characteristics of this insect for biological control and laboratory studies. Photoperiod affects many metabolic and physiological activities of organisms. In this study, were investigated the effect on the amount of total lipid in continuous light and continuous darkness in A. grisella that different age. Studies were carried out under the laboratory conditions at 28 ± 2 ° C temperature and 65 % ± 5 relative humidity. Illumination was done with 40 W fluorescent bulbs in different photoperiod regimes. Calculating the amount of lipids for analysis, van Handel (1985) test was used. Both females and males, the amounts of lipids decreased as the adult aging. Results from this study is show that increase of dark period, caused decrease amounts of lipids. The amount of lipid in females is more than those observed for males

Devamlı Aydınlık ve Devamlı Karanlığın Achroia grisella (Lepidoptera: Pyralidae)’da Değişik Yaştaki Erginlerin Total Lipit Miktarına Etkisi

Öz

Achroia grisella (küçük kovan güvesi) arıcılıkta peteklere zarar veren bir türdür. Bu türün larvaları kovanlarda ciddi zararlara yol açarlar. Bu böcekle yapılacak mücadelede ve laboratuvar çalışmalarında biyolojik özelliklerinin bilinmesi önemlidir. Fotoperiyot canlılarda birçok metabolik ve fizyolojik faaliyeti etkiler. Bu çalışmada, devamlı aydınlık (DA) ve devamlı karanlığın (DK) farklı yaşlardaki A. grisella (küçük kovan güvesi) erginlerinin total lipit miktarına etkisi araştırıldı. Denemeler 28 ± 2 °C ve % 65 ± 5 nisbi nem içeren laboratuvar şartlarında yapıldı. Analizler için stoklanan örneklerdeki total lipit miktarının belirlenmesinde Van Handel [16]’in geliştirmiş olduğu yöntem esas alındı. Farklı fotoperiyot rejimleri 40 wattlık floresans ampullerle sağlandı. Her iki fotoperiyot rejiminde 100 mg ergindeki lipit miktarı her iki eşeyde de yaşla birlikte azalma gösterdi. Her iki fotoperiyot rejiminde yetiştirilen erginlerde dişilerin total olarak erkeklerden daha fazla lipit içerdiği tespit edildi
