    This study was conducted to determine the effects of plant growth-promoting bacteria (Brevibacillus choshinensis) on Eurygaster integriceps Puton, 1881 (Hemiptera: Scutelleridae) and the predators Chrysoperla carnea (Stephens) (Neuroptera: Chrysopidae) and Coccinella septempunctata L. (Coleoptera: Coccinellidae) during the 2022–2023 season. The study was laid out according to a completely randomized factorial design with five replications, including areas with and without B. choshinensis application. Sampling was carried out every 7 days until the harvest period. Predator insect species C. carnea, C. septempunctata and Sunn pest (E. integriceps) found in wheat plots were determined using the visual counting method. According to the results, B. choshinensis treatment boosted beneficial insect population and restriced E. integriceps over control plants. E. integriceps population reduced up to 75%, 100%, 66% and 92% compared to control at the 1st., 2nd., 3rd. and 4th. observation times, respectively. In addition, foliar B. choshinensis treatment reduced E. integriceps population by 6.3-fold (from 0.63 to 0.10) over control plots. Number of beneficial insects per plot were determined as 1.35 and 6.75 at control and PGPB treatmen, respectively, therby increasing by 5-fold over control. In conclusion, it is thought that B. choshinensis can be an alternative bio-insecticide that can be used to control the harmful insect population and to encourage the beneficial insect population. In addition, new researches are needed to understand the mechanisms by which B. choshinensis treatment suppresses E. integriceps populations while attracting beneficial insect communities.

    Nano-Priming as Seed Priming Technology for Sustainable Agriculture
    (Apple Academic Press, 2025-02-21) Fatih Çiğ; Rojin Özek; Murat Erman; Sipan Soysal; Özge Uçar; Zeki Erden; Mustafa Ceritoğlu; Çağdaş Can Toprak; Sönmez Özbey; Muhammad A. Raza; Javeed A. Lone; Saifullah Abro; Muhammad Arshad; Mehmet Efe
    Agriculture is threatened by climate change and by the depletion of resources and biodiversity. Exploring new farming methods is needed to increase crop production and ensure food quality and safety in a sustainable way. Nanotechnology is an emerging trend that contributes to sustaining agricultural production. Seed nano-priming helps improve seed germination, seedling emergence, growth, and yield by resisting various plant stresses. Nano-priming is a more effective method than any other seed preparation method. Studies have shown several benefits of using seed nano-priming. By regulating biochemical pathways and the balance between reactive oxygen species and plant growth hormones, nano-priming helps increase resistance against stresses and diseases with the limited use of pesticides and fertilizers.Moreover, nano-priming prevents the continued damage caused by conventional agriculture, resulting in an environmentally safer system for farmers and consumers. The present review provides an overview of developments in the field, showing the challenges and possibilities of using nanotechnology in seed nano-priming to contribute to sustainable farming practices.
