    Determination of Distribution, Population Change, Infestation and Damage situation of Olive Moth, Prays oleae (Bernard) (Lepidoptera: Praydidae) Causing Damage in Olive Orchards
    (Springer, 2020) Kaplan, Mehmet; Alaserhat, Ismail
    This study was conducted to determine adult population change, infestation and damage rate of Prays oleae Bern. (Lepidoptera: Praydidae) generations which are in leaves, flowers and fruits. Studies were conducted in 30 olive orchards in the Dara village and Derik district of Mardin province in 2016-2017 in Turkey. Samples were collected from three different orchards containing at least 30-40 olive trees. Samplings were done weekly by pheromone traps, visual inspection and shoot methods. As a result of the study, it was determined that Olive moth was distributed in the village of Dara and districts of Derik and Nusaybin, but was not distributed in districts of Kiziltepe of Mardin province. The general infestation ratio of the pest was 73.33% and olive moth had three peak points in a year, such as in early May, second week of June and in early October in the Mardin province. It was found that it had three generations in a year and adults of the pest appeared from April to November in Mardin province. It was also determined that the damage rate of the pest was between 12-21% in leaf generations, 2-5% in flower generations, and between 0.8-5% in fruit generations based on the years and the orchards.

    Ecology, Population Development and Damage of Euphyllura Straminea Log. (Hemiptera: Psyllidae) Causing Damage in Olive Orchards
    (Springer, 2020) Kaplan, Mehmet; Alaserhat, Ismail
    This study was carried out in 2010 and 2011 to determine some biological characteristics and population development of Euphyllura straminea Log. which causes damage in olive orchards (Mardin province) in the south-east of Turkey. In the study, the samples were taken from three different orchards containing 30-40 olive trees. As a result of the study, it was determined that the adults of the pest were present in nature all the year round and hibernated the winter as adult. Adults left their hibernation sites with the warming of the weather and laid eggs in shoots, buds, and flowers. The insect had three annual generations in a year (depending on ecological conditions) and the population density and the ratio of damage decreased especially in rainy years. There is a close relationship between the ecology of E. straminea and plant phenology and climatic conditions.

    INVESTIGATION ON MASS-TRAPPING OF ARCHIPS ROSANUS L. (LEPIDOPTERA: TORTRICIDAE), PEST OF CHERRY TREES
    (Parlar Scientific Publications (P S P), 2019) Kaplan, Mehmet; Alaserhat, Ismail
    Archips rosanus L. (Lepidoptera: Tortricidae), which is found on cherry trees has become the main pest in cherry orchards in Mardin and Elazig province lately. Larvae of A. rosanus damage the cherry trees by feeding on buds, flowers, leaves and fruits. The study was carried out to investigate the effectiveness of mass trapping on the control of the pest in cherry orchards in 2017 year. For this purpose, trap effects, trap parameters and mass trapping studies were performed by using different doses of wine nutrient traps. According to the results, the effects of 10% dose of wine nutrient traps were found to be more effective than %1, %3 and %5 wine nutrient traps with by means of adult individuals caught. With the trap parameter studies, it is shown that must nutrient traps for five trees could be used in mass trapping. The difference between damaged bouquet and fruit and the control was found to be important (p<0.01) in the trials performed by mass trapping with nutrient traps when tested with the chi square test. According to the study results, it is shown that this mass trapping method can be used in the control of the pest successfully.
