Resumo: | In order to analyze the contribution of the natural biological control of the coccinellid predator Scymnus spp. (Coleoptera: Coccinellidae) on Triozoida limbata Enderlein (Hemiptera: Sternorrhyncha: Triozidae), the aim of this research was to study the populational fluctuation of these arthropods in semi-organic orchard of guava and correlate the populational density of this pest with meteorological elements. We used yellow stick traps for monitoring adult of T. limbata and Scymnus spp., spaced approximately 30 m from each other at a height of 1.5 m above the ground, inside random plants. These traps were maintained in the field for 15 days and replaced by new traps, without interruption, totaling 23 samples. We calculated the Pearson correlation coefficients (r) to correlate the populational density of T. limbata with populational fluctuation of Scymnus spp., and meteorological elements. We also made histograms with information about the populational fluctuation of the specimens sampled and temperature (°C) and precipitation (mm) values. The highest densities of adults of T. limbata occurred almost between spring and summer seasons. The populational density of Scymnus spp. was positively correlated with populational density of T. limbata. There was no correlation between the populational fluctuation of T. limbata with meteorological elements.
