The sustainability and protection of this product is extremely important. There are many harmful species seen in olives. The main pest of the olive fly; B. olea. The olive fly (Bactrocera oleae) causes damage both directly and indirectly. The purpose of this review is to obtain more successful results in the control by determining the susceptibility of olive varieties to olive fly (Bactrocera oleae) and the parameters that play a role in the selection of olive fly (Bactrocera oleae). In this review, seasonal flight activity and population dynamics of olive fly (Bactrocera oleae), susceptibility of olive cultivars to olive fly (Bactrocera oleae), effects of pomological characteristics on olive fly (Bactrocera oleae) olive variety selection, olive fly (Bactrocera oleae) on the fruit and the physicochemical changes that occur as a result of the damage caused by the olive fly (Bactrocera oleae) on the fruit are mentioned. Keywords: Olive fly (Bactrocera oleae), olive, resistance, susceptibility, oil content 1. Introduction Olive, one of the most important commercial products of the Mediterranean basin, has become very popular in recent years. It is among the species that contribute the most to CO 2 emissions, especially due to climate change. However, the importance of olive plantations is increasing due to the natural antioxidant and healing effects of olives and olive oil. Today, it is known that there are about 2000 olive varieties all over the world. Olive, whose history dates back thousands of years, is a commercial species that is produced economically in the world. Sustainability of this species is extremely important. During the production of olive products, which have a very important place in the Turkish economy, many diseases and pests cause product and tree losses. The olive fly (Bactrocera oleae), which is among the existing olive pests, is the most important pest of olives. The olive fly (Bactrocera oleae) (Rossi) (Diptera: Tephritidae) is a serious pest affecting olive plantation (Olea europaea, Linneus) in the Mediterranean basin. Although the first emergence of the olive fly (Bactrocera oleae) is in the Mediterranean basin, it can be seen along the east coast of North Africa, the Middle East and South Africa. The olive fly (Bactrocera oleae) has the potential to reduce at least 15% of the worldwide olive production with its direct damage (Bueno and Jones, 2002) [1] . Although the economic loss caused by the olive fly (Bactrocera oleae) varies from year to year, it is approximately $800 million/year (Luchetti, 2002; Genc, 2013) [2] . If the olive fly (Bactrocera oleae) is not taken under control, it causes product losses up to 80% in varieties produced for oil production and up to 100% in varieties grown for table use. The olive fly (Bactrocera oleae) is a monophagous pest in both orchard and marginal areas (Genc and Nation, 2008; Tzanakakis, 2006) [7, 5] . Most of the olive fly (Bactrocera oleae) population spends the winter as pupae a few cm deep in the soil (Moreno, 2005; Álvarez and Moraga, 2007) [6, 10] . Olive fly (Bactrocera oleae) females lay their eggs inside olive fruits (Genc and Nation, 2008) [7] .
