The results of approbation the methods on the example of Lepidoptera larvae of quantitative estimation of miners-phyllobionts harmfulness level taking into account their harm-making ability and harmfulness complex parameters such as feeding, development duration, plant colonization scales, type and effect of damage, occurrence in stands, spectrum and valuation of damaged shrub species, mass reproduction outbreaks were presented. The research was realized in the conditions of the Republic of Belarus. On the base of applied point parameters of the indices used the values of physiologically-conditioned harm-making ability, harmfulness in the aspect of ornamentality decrease according to ecologically determined aspects and total harmfulness were calculated. The most productive was using of harmfulness level parameter in the aspect of decorative effect, which let more effectively differentiate miner phytophages-phyllobionts by harmfulness groups for ornamental shrubs.
