Abstract :This study was conducted between 2017 and 2018 to determine the cultural measures that are applied in the control against Ricania japonica (Hemiptera: Ricaniidae), which has caused damage in the Eastern Black Sea Region of Turkey for approximately 10 years as an important pest. Pests are widespread in this region but there is no other important pest that requires significant chemical control in crop plants, in particular tea plants. Furthermore, this pest population, whose population has grown since 2009, may cause significant losses in vegetables especially for traditional family needs during its nymph period. The fact that vegetable fields have been almost interwened with tea plants and synthetic pesticides are not used in tea plant production, has caused us to focus on cultural methods, which are among alternative pest-fighting methods. With this study, the purpose was to determine the effects of kaolin, refined salt and ash applications against the nymphs of the pests, and to investigate how to destroy the infected plant materials in which the pest lay eggs until the middle of May. As a result of the study, it was determined that the destruction of the infected plants and plant wastes in the areas decreased the pest population by 90% because it was the winter months which is the egg-laying period of the pest. Other applications (kaolin, refined salt and ash) were not found effective against the nymphs of this pest.
