Item Uso de armadilha atrativa na captura de Rhynchophorus palmarum (L) em plantio de dendê na Zona da Mata Norte de Pernambuco(2024-03-08) Santana, Alisson Gomes de; Gonçalves, Maria da Penha Moreira; http://lattes.cnpq.br/0539509819672370; http://lattes.cnpq.br/8309879042134974Item 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.Item Ocorrência de coleobrocas em área em processo de restauração florestal em fragmento de Mata Atlântica nordestina(2021-12-07) Silva, Karina Maria da; Gonçalves, Maria da Penha Moreira; http://lattes.cnpq.br/0539509819672370; http://lattes.cnpq.br/4109193403596589Insects have a great capacity to adapt to environmental changes, being the group of animals with the greatest abundance and richness of species on the globe. The Atlantic Forest is an important biome with a rich diversity of phytophysiognomies, but today it is in an accelerated process of degradation, requiring forest restoration actions, as well as knowledge and monitoring of insects occurring in the biome, which can be used as bioindicators of advance succession. The present work had as objective to know the diversity of beetroot insects in a fragment of Dense Ombrophilous Forest under restoration, in the Northeastern Atlantic Forest. The study was carried out in a fragment under the domain of the Recife Botanical Garden, in an area under restoration and in an area of preserved native forest adjacent to the first. The survey of insects was carried out in September and December 2019, using the Carvalho 47-type ethanol aerial intercept trap, installed at a height of 1.5 meters from the ground. Insects were collected using traps in transects that crossed the two areas, comprising the sense of restored area - border - preserved native forest, with 8 sampling points in each transect. In the two collections, 649 arthropods were captured, belonging to 6 orders, with greater abundance of insects of the order Coleoptera, mainly coleoborcas from the families Cerambycidae, Bostrichidae and Curculionidae (Scolytinae and Platypodinae). The family Curculionidae had the highest number of individuals collected, followed by the family Cerambycidae. The conserved native forest area had a greater amount of beetle borers when compared to the restoration area, due to the fragmentation of the environment. It is necessary to continue collecting in the other months of the year to understand the population dynamics of these groups of insects and understand the influence of the environment on their distribution, as well as the continuity of the forest restoration process in the disturbed environment for the local balance of these populations.Item Efeitos de aditivos em dieta artificial para Neoleucinodes elegantalis (Guenée, 1854) (Lepidoptera: Crambidae)(2020-01-31) Paz, Cássio David Alves da; Siqueira, Herbert Álvaro Abreu de; Silva, Liliane Marques da; http://lattes.cnpq.br/0343944389588686; http://lattes.cnpq.br/6587276520956028; http://lattes.cnpq.br/7788028227038866Tomato production is greatly affected by insect species with pest status. One of the key species of insect pests that most affects this crop is Neoleucinodes elegantalis, (Guenée, 1854), popularly known as the small tomato borer. Chemical control has been the most used method for the control of this pest and the intensive use of insecticides promotes the evolution to resistance. Insecticide resistance in N. elegantalis has not been evidenced by the lack of an adequate toxicological test method, since the larvae of this species penetrate the fruit shortly after hatching. The performance of toxicological tests can be made possible with an artificial diet. Given this scenario, this study aimed to improve an artificial diet designed for a Leucinodes orbonalis (Guenée, 1854) type in order to make it suitable for N. elegantalis. For this purpose, a population of N. elegentalis was maintained on a natural diet. Neonate larvae from this population were inoculated in artificial diets using different procedures of agar, cellulose, vitamins C and E, Vanderzant and Vitagold Vitamin Blend. The results induced a low larval viability, which interfered in the evaluation of the other adopted biological parameters, updating in no satisfactory improvement of the diet. However, the addition of 0.5% cellulose was the concentration that constitutes the increase in larvae viability. Therefore, more studies are included, since obtaining an artificial diet for this species, which helps in mass breeding and in toxicological tests in the laboratory for monitoring resistance, it is extremely important to assist in the integrated management of N. elegantalis.
