Azerbaycan'da farklı yabancı ot mücadele yöntemlerinin badem bahçesinde scarabaeidea (coleoptera) türleri üzerine olan etkisinin araştırılması

This study investigated the population density of Manas larvae in a 1300-decare almond orchard located in the Siyazan Rayon of Azerbaijan. The study was conducted on Ferragnes and Ferraduel almond varieties grafted onto GxN (Garnem) rootstocks, with one Ferraduel pollinator tree planted for every ten Ferragnes trees. During the field studies, the larval population dynamics were monitored by placing random 50 cm x 50 cm frames in both weedy and farmer-managed plots. All larvae in the top 25-30 cm of soil were counted monthly, totaling approximately 3 m³ (around 7 tons) of soil analyzed. The results showed that in farmer-managed plots, the Manas larval population peaked in June and then declined rapidly, while the weedy plots exhibited a more stable population density. This suggests that while farmer practices may initially increase the population, they could eventually exert a suppressive effect. Additionally, it was observed that weeds provided habitat for natural predators that might suppress pest populations. This indicates that weeds may have a potential role as biological control agents. In conclusion, it is recommended to develop more balanced and ecological pest control strategies, encourage the use of biological control methods, and monitor environmental factors to enhance pest management efficiency.
