Abstract:

The present study was conducted to determine some biological criteria such as the first appearance of adults, peak date, and a number of generation for controlling honeydew moth in vineyard in Antalya province, Turkey during 2014 and 2015. In this study, the adult population was determined by pheromone traps and larval population was observed by counting the larvae on the grape clusters. It was determined that the pest adults were first seen in mid-April; however, the population was at very low levels until mid-June. It was demonstrated that the adult population of the pest could generate 4 peaks in June, July, August and September-October. The study results showed that the pest could be important in coastal vineyards. Besides, it has been showed that the effective temperatures sum based on the degree day model that was proposed in the literature could be employed to determine the honeydew moth adult and larval populations in vineyards.
