- Abstract
Aims: Peach twig borer (PTB), Anarsia lineatella Zeller (Lepidoptera: Gelechiidae), is one of the important pests of apricot in Turkey. The study was conducted in 2013-2014 to determine the population density and infestation rates of PTB on early apricot orchards in Anamur district of Mersin province in Turkey. Methods and Results: The study was conducted in five early apricot orchards of the villages Kalınören (Trintina), Ören (Trintina), Cerenler I (Nimfa), Cerenler II (Trintina) and İskele (Trintina) of Anamur district. The peach twig borer of pheromone (E-5 Decenyl acetate 5,0 mg/capsul E5 Decenol 1,0 mg/capsul) was used in Econex polillero trap + DDVP impregnated tablet. Each of sampled orchard contained one pheromone trap. The traps were hanged at South-East direction of the trees about 1.5- 2 m above ground, checked weekly and the caught adults were counted and cleaned.. Randomly chosen 20 trees' twigs (20/tree) and fruits (50/tree) were checked, apart from the trap hanging trees, in order to determine the infestation rates. After two years of the study, the population density of pest varied between each sampling year. In the first year, a total of 46 PTB adults were caught by five pheromone traps at five early apricot orchards. The first adults were caught on 14 April, and the highest number of catches was on 12 May. The highest number of PTB adults was in May with 67.4%, followed by April with 32.6%. In the second year, a total of 66 PTB adults were caught by five pheromone traps at five early apricot orchards. The first adults were caught on 13 April, and the highest number of catches was on 11 May. The highest number of PTB adults was in May with 68.2%, followed by in April with 31.8%. It was observed that PTB had one generation and the pest did not cause any significant infestation on early apricot varieties. Conclusions: The highest number of the PTB adults were caught by pheromone traps in May, following in April in both years. The pest had one genaration and not cause any significant infestation on early apricot varieties. Significance and Impact of the Study: The pests were recoved by pheromone traps at all early apricot orchards and the highest number of adults caught in May, following in April. The pest had one genaration and not cause any significant infestation on early apricot varieties.
