The Population Fluctuations of the Lepidosaphes pistaciae (Archangelskaya) (Homoptera: Diaspididae) pest of pistachio trees in Siirt Province of Turkey

摘要

 The present study was carried out to determine population fluctuations of the pest Lepidosaphes pistaciae (Archangelskaya) (Homoptera: Diaspididae) at two different pistachio orchards in 2003 and 2004 in Siirt province. The high population level of L. pistaciae was determined on pistachio leaves as compared to pistachio shoots and fruits. Populations on the shoots were found to be mature female and they were found to usually pass through winter on 2-3 year-old shoots. L. pistaciae eggs began to hatch in May and made the transition on pistachio leaves and it was determined that they reached the maximum level during the middle and towards the end of July. It was observed that the populations formed on fruits were removed with harvest and that the next year?s population was formed of the leaf populations. The pest gave one offspring in the province of Siirt. According to the results of this study, it was determined that the pest reached high population levels from time to time at both orchards on which population monitoring was made and it was concluded that while determining for struggle against pests, especially the leaf population should be taken into consideration
