Introduction of Rumina decollata (Linnaeus, 1758) for pest snail management in citrus orchards in Türkiye: ecological, economic, and agricultural perspectives

Abstract

ABSTRACT This study assesses the ecological, agricultural, and economic effects of introducing Rumina decollata (Linnaeus, 1758) for pest snail management in citrus orchards within the Yunusoğlu and Düzce districts of Adana, Türkiye. In 2023, a comprehensive survey conducting 20 in-depth questions with three participants was conducted to systematically document farmers’ perspectives and experiences. Qualitative and quantitative data were collected through on-site observations conducted in citrus orchards and their surroundings, with at least 60 visits made throughout the year. The results revealed that R. decollata effectively controls pest snails, Eobania vermiculata and Xeropicta derbentina, reducing their populations by preying on them and their eggs. Other positive implications include reduced chemical pesticide use and lower maintenance requirements for citrus orchards. However, there are negative implications, notably ecological impacts and the risk of species extinction, particularly endemic species, and the potential damages on commercial vegetables. Consequently, this underscores the importance of a balanced approach in introducing non-native and invasive R. decollata for pest control, emphasizing the need for thorough risk assessments and ecological considerations to maintain the delicate equilibrium of ecosystems and agricultural practices.
