期刊介绍:
The Turkish Journal of Entomology is a quarterly journal which has been published by Entomological Society. Turkish Journal of Entomology publishes original research articles in the fields of entomology and agricultural zoology in English. Authors whose native language is not English should have their paper edited professionally prior to submission. Before preparing the typescript for submission, examine the format of manuscripts already published in Turkish Journal of Entomology.
According to TJE rules, biological observations made in one location in only one-year, short notes in which the first record of a single species in Turkey is announced, and research which is older than five years will not be accepted for publication unless it forms part of a longitudinal study.
