The citrus longhorned beetle, Anoplophora chinensis (Forster), native to East Asia, poses a significant threat to various crops and tree species in our country, including hazelnuts, due to its invasive nature and wide host range. In this study, the morphological characteristics of A. chinensis collected from infested hazelnut fields in Arifiye district, Sakarya province in Türkiye, during June, July, and August of 2024, were examined. Various parameters, such as body size, antenna length, elytra structure, and pronotum length, were analyzed on 200 adult beetles (100 ♀, 100 ♂), and distinct differences in morphological parameters between the sexes were observed. Measurements revealed that the body length, width, and elytra length of female individuals averaged 30.94 mm, 11.50 mm, and 22.89 mm, respectively, while male individuals measured 27.68 mm, 10.02 mm, and 20.27 mm. The number of antenna segments was determined to be 11 in both sexes, with the antenna length averaging 38.18 mm in females and 47.85 mm in males. It was observed that females had larger body sizes than males, but males possessed longer antennae. These findings are provided descriptions of some morphological parameters related to the sexes of A. chinensis.
Ethics committee approval was not required for this study due to the use of research materials that did not fall under the definition of experimental animals (The Scientific and Technological Research Council of Türkiye, Animal Experiments Local Ethics Committee Directive, 2018, Article 3-c).
