The population dynamic of honeydew moth [Cryptoblabes gnidiella Mill. (Lepidoptera: Pyralidae)] in vineyard in Antalya

Abstract

Received 13 November 2020 Received in revised form 27 January 2021 Accepted 28 January 2021 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 SeptemberOctober. 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.
