Genus:Platycleis Fieber, 1853 Determination of Harm Forms in Grain Fields of Some Species Güroymak, Bitlis, Türkiye

Abstract

In this study, species belonging to the genus: Platycleis which have shown large population increases in agricultural lands and especially in cereal products in recent years, have been identified and species identifications have been made. Species identified are Platycleis affinis, Fieber, 1853, Platycleis intermedia Serville, 1838 and, Platycleis escalerai escalerai Bolivar, 1899. These species reach a density of 30-50 per m2 in the lands where they are found, and it has been determined that they damage plant products. Although the numbers reached by the species could not reach a herd-like reproduction, it was determined that they caused damage after a certain density. However, it has been observed that they cause economic loss in products. It has been determined that these species increase the damage size by intensifying in certain periods on the crops they damage, wild wheat, wheat, barley, and corn plants. In-plant protection against these pests, preventive measures within the framework of integrated pest management principles, cultural control practices, and the use of biological control agents at the focal point show significant results that appears to have been taken.
