Parks are the most important natural sources of fresh air and relaxation in a city like Timisoara. Therefore, in this paper we turned our attention to the factors that can disrupt the development of ornamental plants in the main parks. One of them is harmful insects that can affect in the medium or long term the species of plants. Thus, during 2020, between April and September, 125 observation points in 5 parks were analyzed to establish the level of abundance of insect populations. In this analysis, we considered 4 levels of evaluation: level I, extremely high (> 400 individuals), level II, high (250-400 individuals), level III, medium (100-250 individuals) and level IV, low (<100 individuals). Levels I and II included the species of Metcalfa pruinosa, Eriosoma lanigerum, Aphis rosae, Aphis gossypii, Trialeurodes vaporariorum, Corythucha ciliata and Halyomorpha halys, which had high and extremely high values in 2 parks (Botanical and Roses). Increased attention should be paid to these pests which in the absence of a control strategy can multiply excessively causing qualitative and quantitative losses of plant species.
