Abstract:

This study was conducted at persimmon orchards in Adana Province in 2011-2014. In the study, it was aimed to determine the adult population fluctuation, control and damage rate of Honeydew moth [Cryptoblabes gnidiella Milliere, 1867 (Lepidoptera: Pyralidae)]. The population fluctuation of the pest was observed with the sex pheromone traps where as its contol was made by biological insecticide. It was determined that first C. gnidiella adults were catched at the traps in april. The pest population was low at the beginning of the vegetation period, started to increase from the half of july and at the highest population in october-november. It was determined that C. gnidiella had 5 generations per year at the persimmon orchard. Bacillus thuringiensis preparation was effective to C. gnidilella at a rate of averagely 88.99% and 90.84% in 2012 and 2013, respectively. The infected fruit ratio was determined as between 3.1-26.7% in the persimmon orchards in different districts of Adana.
