Abstract
ABSTRACT: The Knowledge of the initial diversity of entomofauna in eucalyptus spp forest stands. it can provide an effective characterization of the insect community, evidencing aspects of local diversity, besides contributing to the registration of insect pests with potential for crop damage, biological control agents, pollinators among other organisms and their complex trophic networks. Thus, the study aimed to perform the survey and faunistic analysis of the entomofauna associated with clonal experimental forest settlement of the hybrid Eucalyptus urograndis (clones TP361, VCC865, I144 and VE41), through manual collection in the State of Alagoas. The collections were carried out between January 2018 and January 2019 in six-month-old plots, and the branches of the plants were evaluated, analyzing the presence of individuals. The diversity of entomofauna and faunistic indices were determined using the ANAFAU software. A total of 577 individuals were collected, distributed in 10 orders, and coleoptera orders (30.4%), Hemiptera (23.58%) and Hymenoptera (13.73) the ones that stood out the most for the greater number of captured individuals. The Chrysomelidae family presented expressive indexes for all clones evaluated, due to a population outbreak of C. ferruginea in the study area. Clone I144 presented higher diversity value of Shannon-Weaner (H') (2.7) when compared to the other clones, TP361 (2.6), VE41 (2.5) and clone VCC865 (2.4), which presented lower diversity index. KEYWORDS: Manual collection, Entomofauna, Faunistic indexes.

Diversidade inicial da entomofauna em povoamento florestal de eucalipto, no município de Rio Largo, Alagoas. Initial diversity of entomofauna in eucalyptus forest stands, in the municipality of Rio Largo, Alagoas. O estudo teve como objetivo realizar o levantamento e análise faunística da entomofauna associada a povoamento florestal experimental clonal do híbrido Eucalyptus urograndis (clones TP361, VCC865, I144 e VE41), através de coleta manual no Estado de Alagoas. A diversidade da entomofauna e os índices faunísticos foram determinados através do software ANAFAU. Foram coletados um total de 577 indivíduos, distribuídos em 10 ordens, sendo as ordens Coleoptera (30,4%), Hemiptera (23,58%) e Hymenoptera (13,73) as que mais se destacaram pelo maior número de indivíduos capturados. A família Chrysomelidae apresentou índices expressivos para todos os clones avaliados, em decorrência de surto populacional de C. ferruginea na área de estudo.
