V.V. Rubtsov, I.A. Utkina Long-term Dynamics of Winter Moth Populations in Oak Stands of Forest-Steppe Zone // Forest Science (Lesovedenie). 2011. No 5. С.36-45. The winter moth (Operophtera brumata L., Geometridae, Lepidoptera) is a polyphagous insect with discrete range in Eurasia and North America. It feeds with foliage of nearly a hundred of plants, including forest and garden trees and shrubs. This species is included in the list of forest pests for annual forest pathological monitoring in all subjects of the Russian Federation because of its significant damage to forest management by declining of trees, disturbing their physiological processes and decreasing annual increment of stem wood during mass propagation outbreaks. If severe damage repeats several successive years, the death of trees is possible. In Russia, outbreaks of winter moth are rather frequent in stands of forest-steppe zone, where oak and elm trees are damaged first of all. The frequency and regularity of outbreaks is discussed with taking different environmental factors into account. Winter moth is a traditional object for entomological and ecological studies in many regions of Europe. Recently, the quantity of publications about the impact of climate changes on interactions between winter moth and its host trees increases. Partially, the disruption of the synchrony of oak and winter moth phenology in the view of its negative effect for next stages of trophic chains is discussed. Winter moth, outbreaks, seasonal activity, oak stands of forest-steppe zone. |
