Рассмотрены примеры развития очагов массового размножения вредителей леса, которые на большей части своего ареала являются редкими. Некоторые из них внесены в красные книги России или ее регионов. Причины, приводящие к возникновению очагов таких насекомых, как и закономерности развития вспышек их численности, не известны.

MODELING OF THE PREVENTION AND CONTROL OF FOREST PEST
Journal of Biological Systems, 2007In most models of pest control, the time of prevention and control is always assumed to be unrestricted. In practice, however, it is usually required in agriculture and forestry that we control the pest density to be lower than the economic injury level in a given time.

Considerable interest now exists in understanding how the host tree, pest population, associated microorganisms, and the environment interact to determine if a pest outbreak will occur. However, most research in the past has focused on individual components which determine pest outbreaks. To address management of “pest” stress it will be essential that

Forest pest management sociopolitics
Forest Ecology and Management, 1991Abstract Successful forest pest managers must integrate complex technical considerations with important social and political concerns. Forest managers well trained in silviculture or entomology may be prepared for the biological challenges, but they may not be prepared for the sociopolitics.

Pest Management in Tropical Forests
2020For pest management to be an integral part of forest resource management, a “look-ahead” policy must be in place. Monitoring is an important step while formulating the management strategies in forestry. Mechanical and physical methods serve as barriers and prevent insect pests from establishing on host plants.

SUMMARY The attack toy termites on indigenous eucalypt forests in Australia results in a serious loss of timber. Porotermes adamsoni is the most serious pest of alpine forests in New South Wales, Tasmania, and Victoria; and two species of Coptotermes (C. acinaciformis and C.

The term pest describes those organisms that have a negative impact on human survival or well-being, either acting as parasites; transmitting pathogens; competing with humans for food, fiber, or other useful resources; or just plain annoying them. The term pest, therefore, is highly subjective and reflects the human viewpoint.

Forests must be managed in ways different from farmlands. In agriculture, a grower is responsible for preparing the soil and selecting, planting, and harvesting the crop. Management options such as fertilization, irrigation, and pest control are available at most every phase of production. Each year a crop is harvested and sold.

The Urban Forest Can Be A Pest
Arboriculture & Urban Forestry, 1986Abstract“Pest” is frequently defined as anything that causes trouble, annoyance, or discomfort. Almost everyone hears about the benefits of trees for the urban environment. If management recognizes the pest potential of the urban forest, it can be the asset it was intended to be in our urban areas. Urban forests and trees usually become a pest (1) when

Pest management on street trees in the U.S. aims to protect an asset worth nearly $30 billion plus an investment of over $425 million dollars per year, or $10.62 per managed tree. Tree care accounts for only .49% of city budgets, and spraying, a major pest control method, is only 4% of that. Only 36% of responding cities monitor for pests.
