The aim of this work was to determine the population of the coleopterofaune xilophagous in the municipality of Pinheiral, Rio de Janeiro State, Brazil, with the used of traps impact, baiting with ethanolic-extract. Thirteen host plants were utilized, distributed at seventeen botanical families, occupation an area of 10 hectare. The strategy to data collected was based in fixed of traps in different positions, between 1,5 and 3,5 m above the ground, according to botanical species. The work it was conducted in the area of the Colegio Agrcola Nilo PeYanha of the Federal University Fluminense. The distribution of data was in interaction with the meteorological factors. After quantified the copies in this respectively host of coleopterons have reported the following bioecological association: Leguminosae (357 individuals), Mirtaceae (345), Anacardiaceae (223) and Rubiaceae (167), represents 60,9% of total were captured. This values are representative of 50% of the host plant evaluated, it is, 1.092 individuals (60,9%). In total, were found 1.793 individuals. However, 90,6% were constituted of, mainly, representatives of Scolytidae (877 individuals), Cerambycidae (284), Platypodidae (197), Bostrichidae (153) and Curculionidae (104) families. The results of obtained demonstrated, in comparison of the averages that the number of coleopterons, was highly significant for 1% and the best comparisons, were in relation to interaction with minimum and maxim temperatures and relative humidity, respectively (P< 0,001), in the region of the Southern of Rio de Janeiro, State, Brazil.
