Almond moth (Eurytoma amygdali Enderlein) is one of the most important pests of almond. Pest ratio can be as high as 95% in some areas in case it is not fought against. The study was conducted to determine the preferences of Almond moth for some almond varieties (Ferragnes, Ferraduel, Nonpareil, Drake, Cristomorto and Garrigues) in the years 2017 and 2018. Furthermore, times of emerging of the pest in Malatya Province and the number of individuals emerging from damages fruits based on years were determined. Cage observations were carried out and fruits were counted under field conditions and were related to meteorological data. It was fund in the study that the smallest contamination rate of E. amygdali was in Ferragnes variety (81%) followed by Cristomorto variety (%85). The highest contamination rate, however, was found in Nonpareil variety (97%). While the rate of emerging of the pests as adults in year one was 89.3%, rate of individuals passing down to the next generation was 10.6%. It was found in the study that the time of emergence as adults of Almond moth in Malatya was the end of April when the maximum air temperature was 25oC and the daily mean temperature is higher than 15oC, and when the temperatures are routinely around these levels.

Apricot flower midge (Contarinia pruniflorum) emerged in February-March and lay eggs on the flower buds of the apricot trees. The larvae hatching feeds through the bud wall and flower genital organs. The damaged flower does not turn into fruit. It is a pest that directly affects the yield.prevalence areas in apricot orchards in Malatya (Turkey) and the damage rate were determined. The highest infestation rate of the pest is in Kale and Battalgazi districts of Malatya and Baskil district of Elazığ with 100 %, then, Yeşilyurt 95%,Yazıhan 90%,Akçadağ 76%, Darende 75%, Kuluncak 50%, Arguvan 50% and Doğanşehir 12.5% followed by infestation rates. No pests were found in the orchards which were controlled in Hekimhan district of Malatya and Elbistan district of Kahramanmaraş. Although the damage rate varies according to years, it was determined that the flower damage rate was 0.7% and the fruit set rate was 10.6 % in orchard in Kale where the pest control is done, while the damage rate was 11.8% and the fruit set rate was 2.9% in the orchard without pest control in 2017.In 2018, when compared with orchards with or without pest control, while there was damage in the number of flowers, but there was no change in the amount of fruit.

Apricot flower midge (Contarinia pruniflorum Coutin & Rambier Diptera: Cecidomyiidae) was first detected in Prunus species in the 1950s and did not become a significant pest for a long time. However, towards the 2000s, the pest caused damage to apricot and plum especially in Mediterranean countries and its distribution continued to increase. The population density of the pest is closely related to the climate of the agricultural area. In recent years, the fluctuation in climatic data causes the population fluctuations. The study was carried out in the Kale and the Yeşilyurt district of Malatya province (Turkey) in 2017-2018. Some biological stages of apricot flower midge were determined in Malatya province and these data were interpreted together with climatic data. It was determined that the pest overwinters as a pupa in the soil. In February, the adult emerges from the pupa with the warming of the air and soil temperatures. It was determined that the adult emerged from the pupa when the soil temperature was 13-14 °C and the air temperature was 7-15 °C. At the beginning of the pink-bud stage of apricot, the pests lay eggs into flower buds. The larval development is approximately 25-28 days. The average number of larvae in the damaged buds was 14, the maximum number of larvae in a bud was 26, and the pest gave an offspring annually and the ratio of male to female was 0.08.

The Apricot flower midge (Contarinia pruniflorum) is a pest of stone fruit trees and lays its eggs in the flower buds before the pink bud stage of the apricot. It is a pest that has a direct impact on the yield of the tree. This study was conducted in 2017-2018 in Malatya province of Türkiye to determine the morphological characteristics of certain biological stages of Contarinia pruniflorum. In the morphological examinations, the morphological characteristics of the adult female, adult male, mature larva, and pupa were described and measurements were made on some body parts. The average body width of the adult female is 0.43 mm, with a length without antennae of 1.81 mm. The average antenna length is 0.91 mm and consists of 12 segments. The average body width of the adult male is 0.34 mm and the body length excluding antennae is 1.68 mm. The mature larva has an average width of 0.49 mm and a length of 2.17 mm. The pupa has an average width of 1.09 mm and a length of 2.22 mm. The study contributed to population monitoring by introducing the pest to growers and researchers.

Çalışma; Malatya ili kayısı alanlarında yayılış gösteren Eurytoma schreineri Schr. (Hymenoptera: Eurytomidae )’ nin bulaşıklık oranını, zarar durumunu ve ergin çıkış zamanını belirlenmesi amacıyla, 2013-2014 yılları arasında yürütülmüştür. Proje kapsamında Malatya ilinde Merkez ve 14 ilçeye bağlı 42 köyde toplam 84 bahçede örneklemeler yapılmıştır. Zararlının, Akçadağ, Darende, Hekimhan ve Yazıhan ilçelerinde yayılış gösterdiği belirlenmiştir. Bulaşma oranını belirleme çalışmalarında ise, yapılan örneklemelerde %3-%11 oranında bulaşıklık oranı tespit edilmiştir. Doğada ergin çıkış zamanının belirlenmesi çalışmaları kapsamında ise Darende ve Hekimhan ilçelerinde zararlının ergin çıkışlarının Mart ayının son haftasında gerçekleştiği tespit edilmiştir. Bu çalışma; Malatya ili kayısı alanlarında zararlıya karşı yapılacak mücadeleye yönelik ilk veriler içermesi açısından önemlidir.
