Red spiders cause significant damage in all areas where the apple is produced. In our country, chemical struggle is preferred in the fight against red spiders and other harmful ones. Many negative aspects of chemical struggle have been revealed today. Red spiders have many natural enemies, and it is important to determine their effectiveness first and foremost. Neoseiulus californicus (McGregor) is an important hunting species used in the fight against red spiders. In this study, the fight against red spiders in apple gardens has also determined the freezing rate and effectiveness of the hunter's N. californicus in different proportions. For this purpose, two different experiments were established in two different apple gardens in the same area. The work was established by random test parsels. In the parcels, 25, 50 and 100 hunters (NC) were released per tree. No control has been done. N. californicus released in the apple garden in the village of Çavundur, control, 25, 50 and 100 NC/tree released in the gardens in the 63rd day, respectively, an average of 10.31, 2.58, 1.96 and 1.69 pieces of red spider moving period (hd)/fabricated and 8.09, 1.11, 0.66 and 1.16 eggs/fabricated. In the Alcıklar neighborhood, the control, 25, 50 and 100 NC/tree releases in the gardens in the 63rd day, respectively, average 4.53, 1.02, 0.49 and 0.49 hd/tree and the average 3.11, 0.67, 0.36 and 0.31 eggs/tree according to the same order. As a result, in all applications, red spider populations were under pressure at different times according to control.
