Abstract:

The Honeydew Moth, Cryptoblabes gnidiella Mill. (Lepidoptera: Pyralidae), is one of the most important pest of pomegranate in Turkey. This study was conducted to determine the distribution, population density and damage rate of Honeydew Moth on pomegranate orchards in Hatay province using pheremone ((Z)-11-hexadecenal (Z11-16: Ald), (e)-11-hexadecenal (E11-16: Ald), (Z) -13 - octadecenal (Z13-18: Ald), and (E)-13-octadecenal (E13-18: Ald)) (duration 40 days) in Econex Delta traps. The study was carried out in seven different pomegranate orchards between 27 May and 23 December 2012 and in four different orchards between 5 May and 8 December 2013. All of the orchards were composed of 'Hicaz' variety. Pheromone traps were checked weekly and captured adults were counted and cleaned. Pheromone dispensers in the delta traps were replaced with new ones in every 40 days. During the harvest time, except for the ones from pheromone trap hanging tree, 100 pomegranate fruits were randomly selected to evaluate the number of the damaged fruits in each pomegranate orchard. The Honeydew Moth was caught in all of the pomegranate orchards. The population density of Honeydew Moth was significantly different in each of the sampled pomegranate orchards. For the first year, the highest number of the Honeydew Moth adults caught was in October, following in September, August, July, June, November and December. In the second year, the highest number caught was in September, following in October, August, July, November, June, December and May. The damage rates observed were ranged from 4.5% to 9.5 % in 2012 and 6.75% to 12.25% in 2013. According to the results, the Honeydew Moth had 4 generations in Hatay pomegranate orchards. An IPM program should be developed to control the pest.
