Item Levantamento populacional de coleobrocas associadas a espécies florestais sob monocultivo em Goiana - PE(2023-09-15) Lima, Paloma Richelle dos Santos; Gonçalves, Maria da Penha Moreira; http://lattes.cnpq.br/0539509819672370; http://lattes.cnpq.br/3119218064534593In forest environments, whether natural or cultivated, there is always the chance of harmful insect species occurring. However, coleoborers stand out, which act as pests, whose knowledge of the damage caused to forests and wood is extremely important in some cultivated forest species. In this sense, the study aimed to understand the diversity and measure the population fluctuation of coleoborer insects in three forest plantations in Zona da Mata Norte Pernambucana. The forest plantations with the species Eucaliptus spp, Mimosa caesalpinifolia and Hevea brasiliensis are located at the Experimental Station of the Empresa Pernambucana de Pesquisa Agropecuária (IPA) of Itapirema, in the municipality of Goiana, in the Zona da Mata Norte of the state of Pernambuco. The insects were collected using aerial interception traps, model Carvalho 47, installed at three sampling points in each forest plantation. They were then transported to the Forest Protection Laboratory of the Forest Science Department of the Federal University of Pernambuco for identification. 276 individuals were collected, grouped into three families/subfamilies (Bostrichidae, Cerambycidae and Scolytinae). A predominance of individuals from the Scotylinae family was observed (86.23%), occurring in the three plantations. Although in smaller numbers, the Cerambycidae family also occurred in different areas. Regarding population fluctuation, in the first week of collection the largest number of species was collected, 34 in the Hevea brasiliensis planting, 31 in the Eucaliptus spp planting and 14 in the Mimosa caesalpinifolia planting. The fluctuation of insects in the planting of Eucaliptus spp was decreasing. However, in the cultivation of Hevea brasiliensis, there was a significant reduction in the third week, with the collection of only eight individuals. While there was a reduction in Sabiá planting, in the second and third week, respectively. The results suggest that factors such as the age of trees, their specific characteristics and environmental conditions play important roles in population fluctuation and interactions between coleoptera entomofauna and trees.
