Ground Beetles (Coleoptera: Carabidae) in Different Agroecosystems of Southeast Kazakhstan

Abstract

The recent study on ground beetles (Carabidae) was carried out in 2020 over five different agroecosystems, i.e., alfalfa, barley, corn, soybean, and triticale, at the Kaskelen Experimental Farm, Southeast Kazakhstan. Overall, 38 species of ground beetles related to 24 genera were identified. From these, the Harpаlus rufipes, Poecilus cupreus, and P. versicolor were the dominant ones in the different agroecosystems. Most of the ground beetles are general predators and useful as entomophages. These beetles and their larvae exterminate various agricultural pests. However, the presence of P. versicolorand P. cupreus suggests a threat to the crops. Those species have a mixed diet and are also known as economically significant pests, of which the most famous is the ground beetle Zabrus morio. Different agroecosystems have shown different distributions of ground beetle species, indicating the influence of cultivated crops on the formation of the ground beetle community. Findings from the study could provide the basis for designing crop management programs after promoting the presence of ground beetles that can contribute to the prevention and control of agricultural pests.

Reforestation Potential of Tugai Forests in the Floodplains of Syr Darya and Ili Rivers in the Territory of Kazakhstan

“…Damage caused by leaf-eating insects to the foliage also showed on the silver loch. Root-gnawing insect pests (crustaceans) were visible in small quantities (less than one piece per square meter) (Babayan, 2022;Saimova et al, 2022). Also, according to a detailed examination, the average degree of damage by leaf-gnawing and gall-forming insect pests of -Litvinov's and Raznolistnaya Turanga‖ and the narrow-leaved loch was more than 50%.…”

“…A reconnaissance survey, which is a visual method of detecting mass leaf-eating insects and their accounting, went on in the territory of tugai forests in the Otrar State Institution for the Protection of Forests and Wildlife of the Turkestan region and the Bakanasky forestry of the Almaty region of Kazakhstan (Figure 2). The reconnaissance survey continued on selected sites in plantings characteristic of the occurrence of foci of harmful forest insects, and by inspecting the route passages crossing such plantings (Babayan, 2022;Saimova et al, 2022). The investigations ran according to…”
