Utilização de armadilhas adesivas para o levantamento das principais ordens de insetos na cultura do Pinus taeda

Abstract

Knowing the entomological population of a forest stand makes it possible to understand the population dynamics and fluctuation of the main orders present in a reforestation. This work aims to survey the main orders of insects in the pine culture through the use of yellow colored adhesive traps. The experiment was carried out in the municipality of Enéas Marques, in the southwestern region of Paraná. Adhesive yellow traps were installed in a 10-year-old Pinus taedaforest plantation. The 10 collection points were evenly distributed, with 2 yellow adhesive traps per point, one on the line and the other between the planting line. Nine collections were carried out between January 2019 and September 2019, the adhesive traps were collected, replaced monthly and evaluated at the Biological Control Laboratory I and II of the Federal Technological University of Paraná, Câmpus Dois Vizinhos. Performing the classification of insects in their respective orders and counting of individuals collected. 3218 insects belonging to the orders Hemiptera, Hynemoptera, Diptera, Lepidoptera, Coleoptera, Blattodea, Mantodea, Orthoptera and Phasmatodea were identified, evaluating the population fluctuation of each order according to the data collected in relation to the average temperature variables of the period and precipitation average for the period. It was found that the main orders found in the population of P. taedawere the orders Hemiptera with 1573 individuals, Diptera with 903 individuals, Hymenoptera with 533 individuals and Coleoptera with 153 individuals. The use of yellow adhesive traps for the entomological survey in the culture of pine showed a total of 9 different orders of insects and 3218 individuals collected. The variation in average temperature and average precipitation, associated with forestry treatments, had an influence on the number of individuals collected during the study period.
