Hemerobiidae (Neuroptera) in the midwestern region of Minas Gerais State, Brazil

Abstract

This study aimed to identify the Hemerobiidae (Neuroptera) associated to Brazilian savannah and gallery forest, in Minas Gerais State, Brazil. The sampling was carried every two weeks at Brazilian savannah (Cerrado) in Divinópolis and at gallery forest in Pedra do Indaiá, both in Minas Gerais State, Brazil. Collecting was carried out between November 2003 and October 2004, with Malaise traps. A total of 181 specimens of five species of Hemerobiidae were collected. The species Nusalala tessellata, Megalomus impudicus, Hemerobius bolivari and Notiobiella sp. were collected in the two sites; the fifth species Sympherobius sp. was found only in Pedra do Indaiá. The species of diversity (index of Shannon-Wiener) and the equitability (J) of Hemerobiidae were similar in the areas of Brazilian savannah and gallery forest (H’ = 0.47 - 0.49, respectively, and J = 0.78 - 0.69, respectively), and the differences observed between the two locations were not significant.

“…In Brazil, Nusalala and Hemerobius were reported in several studies carried out in agricultural Freitas, 2002, 2003;Lara et al, 2008Lara et al, , 2010Lara et al, , 2020Melo et al, 2020) and wild environments (Oliveira et al, 2013;Lara and Perioto, 2021;Schuster and Machado, 2021), and in most of them, Nusalala was the most abundant genus. However, in all these studies, Megalomus, Notiobiella and Sympherobius are genera, so far, poorly represented in population surveys conducted by the authors in agroecosystems and wild environments.…”

“…These results may be related to the need for intense and long-term efforts for Hemerobiidae sampling. The sampling of Neuroptera was addressed by different authors, who stated that, for some groups, is required the combined use of greater and longer sampling efforts and the use of various types of traps (Szentkirályi, 1992(Szentkirályi, , 1997Ábrahám et al, 2003;Lara et al, 2008;Oliveira et al, 2013;Martins et al, 2019;Sarmiento-Cordero et al, 2021).…”

“…In Brazil, Oliveira et al (2013) reported that the highest frequencies of Nusalala in areas of Brazilian savanna and gallery forest areas in the state of Minas Gerais occurred in winter. Lara and Perioto (2021) studied the hemerobiids in areas of Brazilian savanna in the state of Goiás and found that the higher capture frequencies occurred in the fall and winter.…”

“…Lara and Perioto (2021) studied the hemerobiids in areas of Brazilian savanna in the state of Goiás and found that the higher capture frequencies occurred in the fall and winter. In the state of Minas Gerais, Silva et al (2015) reported that the highest frequencies of Hemerobius in semi-deciduous and riparian forests occurred in the spring and summer, while Oliveira et al (2013) recorded these predators in late winter. Lara and Perioto (2021) collected Hemerobius sporadically in the mid-autumn, winter and spring.…”

“…There is a lack of long-term research on the frequency and seasonality of several groups of Neuropterida, among these hemerobiids, usually collected in low population density, which also makes it necessary to use different sampling methods to describe its seasonal activity (Szentkirályi, 1992(Szentkirályi, , 1997Ábrahám et al, 2003;Lara et al, 2008;Oliveira et al, 2013;Sarmiento-Cordero et al, 2021). Information about distribution patterns and diversity of hemerobiids along environmental gradients are also unusual (Cancino-López et al, 2022).…”
