Modern forest pathological state of the walnut-fruit forests of Kyrgyzstan

The forest pathological state of the walnut-fruit forests of Kyrgyzstan was studied. The main factors influencing the degradation of walnut-fruit forests have been identified. It is shown that the main pests of the forest in recent years are gypsy moth (Lymantria dispar L.), cherry slimy sawfly (Caliroa cerasi L.), apple ermine moth (Yponomeuta malinella Zell.), apple codling moth (Cydia pomonella L.), blood apple aphids – (Eriosoma lanigerum Hausm), Turkestan peacock-eye (Neoris stroliczkana schenki Stgr.), Turkestan goldtail (Euproctis karghalica Moore.), California scale insect (Quadraspidiotus perniciosus Comstok), skinned moth (Erannis defoliaria Cl.), mountain ringed silkworm (Malacosoma parallela Stgr.), plum false scale insect (Sphaerolecanium prunastri Fonsc.), pistachio codling moth (Recurvaria pistaciicola Danil), pistachio pachyderm (Eurytoma plotnikovi Nik.), pistachio seed beetle (Megastigmus pistaciae Walk.), poplar leaf beetle (Chrysomela populi L.), leafworms, etc. Of the diseases of the forest on fruit crops, an outbreak is given by soot fungus, bacterial burn, powdery mildew (Podosphera leucotricha Salm.), apple scab (Venturia inaequalis Wint.), etc. The bioecological features of the cherry slimy sawfly were studied and recommendations were given for the biological control of the main pests and diseases of the forest.
