In the paper there are presented the results of the researches of existing methods of quality control for cultures of insects for rearing is presented. It is shown that there is a need to search for new approaches to solving this problem. Testing of new methods of control and prediction of biological material viability was carried out on a laboratory culture of the fall webworm moth (Hyphantria cunea Drury). It was found that intensity of taxis manifestation can be considered as a criterion of population condition. This selection method can be used also for assessment of culture viability. A new express-method of biological material selection for H. cunea establishment has been approbated. It is based on the positive correlation between insect viability parameters and their trophotaxis intensity. This method may be suitable for monitoring of natural populations condition in systems of integrated plant protections of different agricultural, ornamental and forest crops with intensive anthropogenic loading.
