Technical Abstract: The strategy of using exotic phytophagus insects in a sustained effort to control plant pest populations has had many unequivocal successes, partial successes and unexplained failures. Where success has been less than complete, an inability of the insects to overwinter in numbers sufficient to maintain control of the plant pest may be the cause of a program failure. This presentation examines the relationships of ice nucleating active agents (INA) with overwintering insects and earmarks areas where INAs can cause problems for non-native insect species. Approaches for assessment of INA barriers and the possible remedies will be presented.
