Аннотация: The authors consider three interaction models ''resource - consumer''. ''Null model'' is basic for the rest ones because in its frame the antibiosis of feeding objects does not take into consideration. According to reparation model feeding objects be either accessible for consumption or exist in reparation state if the high concentration of protection substances does not allow the population of consumers to continue feeding. Complicated model includes three states of feeding object: it is accessible and not attacked by insects, it is accessible and attacked and feeding object exists in reparation state. This model takes into consideration a set of different effects, for instance the effect of slow development of reparation processes. The changes taking place under pollution influence with different parameters of ''resource - consumer''interaction are characterised. The authors suggest the classification of different ''resource - consumer'' models based on resource characters. All models show the exponential decrease in the portion of non-damaged feeding objects while they contact with consumers. Change of this portion allows to measure the rate of consumer attack, whereas the dynamic of total number of damages characterizes the reparation characteristics. The authors investigate the damage of Populus leaves by insects in plots situated in Krasnoyarsk in regions with different antropogenic influence. The dynamic of damages shows the high degree of consent with the models. They can be useful for entomological indication to evaluate the state of separate trees or the whole stand.
