Fluctuations in the population level of an insect species relative to the general equilibrium position (GEP), economic threshold (ET), and economic injury (EIL). Irradiation Microbial insecticides Pesticides Pest-resistant crop varieties Planting time Quarantines Repellents Sanding* Sound Tissue Culture Propagation Traps Trap crops Both the second and third points necessitate that professional people in many disciplines cooperate in developing a management strategy for all types of pests on each crop. Disciplines that should be involved in coopera- tive planning, research, and implementation include entomology, weed science, plant pathology, agronomy, horti- culture, plant physiology, vertebrate zoology, agricultural economics, plant breeding, toxicology, chemistry, and biochemistry. In the past, workers in each discipline independently studied pest problems on specific crops. Generally, they issued reco- mmendations for control without taking into account negative impacts on beneficial organisms and plant develop- ment. Neither did they consider how their recommendations might complement or conflict with recommendations made by workers in other disciplines. •Peculiar to the cranberry industry.
