260006 One of the major difficulties in the biological control of insect pests is the:

1 practical difficulty of introducing the predator to specific areas
2 method is less effective as compared with the use of insecticides
3 predator does not always survive when transferred to a new environment
4 predator develops a preference to other diets and may itself become a pest
