General Concepts of Biological Control
Virtually all pest populations are affected by natural enemies to some extent. In
many cases, natural enemies are the primary regulating force of the pest populations.
Important Components of a Successful Pest Management Program
“The lowest population density of a pest that will cause economic damage; or the
amount of pest injury which will justify the cost of control.”
Pest Management Decision-making: The Economic-injury Level Concept
Pest managers cannot afford to take a pest management action without knowing if it
is economically sound. Treating a pest needlessly is not conducive to making a profit.
The Integrated Pest Management (IPM) Concept
The term Pest Management came about in the early 1960’s, which then evolved into Integrated
Pest Management (IPM). However, many aspects of IPM have been practiced since plants
were first cultivated by humans.
Using Degree Days to Time Treatments for Insect Pests
Insecticides that are applied for a perennial insect pest based on a calendar date
often result in poor insect control and a waste of resources. Insect activity varies
from year to year depending on weather.
