ABSTRACT

ABSTRACT A survey of the brown lacewings (Neuroptera, Hemerobiidae) was carried out with five Malaise traps/area in five areas in Atlantic rainforest of São Paulo State, Brazil, between October 2009 and December 2011. 237 specimens of Hemerobiidae were obtained belonging to 14 species and five genera: Nusalala tessellata (Gerstaecker, 1888) (31.6% of the total collected), Hemerobius hernandezi Monserrat, 1996 (26.0%), Nusalala dispar (Banks, 1910) (17.7%), H. cubanus Banks, 1930, H. edui Monserrat, 1991, H. nigridorsus Monserrat, 1996 and H. withycombei (Kimmins, 1928) (1.7% each), H gaitoi Monserrat, 1996, Megalomus ricoi Monserrat, 1997 and Notiobiella cixiiformis (Gerstaecker, 1888) (1.3% each), Sympherobius ariasi Penny & Monserrat, 1985 (0.9%) and, M. impudicus (Gerstaecker, 1888), M. rafaeli Penny & Monserrat, 1985 and S. mirandus (Navás, 1920) (0.4% each). Eighteen specimens of Hemerobius Linnaeus, 1758 and nine of Megalomus Rambur, 1842, totaling 11.4% of the collected Hemerobiidae, could not be identified at the species level. The hemerobiids were more frequent in the Parque Estadual Intervales (55.3% of the total collected) and in the Parque Estadual Morro do Diabo (23.2%), inland collection sites in the state of São Paulo, with higher abundances recorded in spring (43.9% of the total collected) and in winter (37.1%). This study extends the geographic distribution range of five species of Hemerobiidae to Brazil and three to the state of São Paulo.

ABSTRACT

Este estudo teve por objetivo avaliar métodos de amostragem, abundância sazonal e diversidade da população de Hemerobiidae associada a cultivo de café Coffea arabica L. cv. Obatã em Cravinhos, São Paulo, Brasil. Para tanto foram realizadas amostragens semanais no período de maio de 2005 a abril de 2006. Os métodos de amostragem utilizados foram: rede de varredura e armadilhas de Mõericke e luminosa. Foram coletados 491 exemplares de Hemerobiidae pertencentes a quatro gêneros: Nusalala (231 espécimes / 47,2 por cento do total de hemerobiídeos coletados), Megalomus (110 / 22,5 por cento), Hemerobius (104 / 21,3 por cento) e Sympherobius (44 / 9 por cento). A rede de varredura foi a mais eficiente para a captura de Hemerobiidae e a armadilha de Mõericke foi o método de amostragem que apresentou os maiores valores de diversidade (H'= 0,56) e de equitabilidade (J= 0,93). Os hemerobiídeos estiveram presentes na área estudada durante o ano todo; as maiores freqüências foram registradas entre agosto e março (final do inverno, primavera e verão) e o maior pico populacional ocorreu em janeiro (na metade do verão). Megalomus apresentou correlação positiva e significativa (p< 0,05) com a precipitação pluviométrica e as temperaturas máxima e mínima; Nusalala com as temperaturas máxima e mínima e, Sympherobius apenas com a temperatura máxima.


This study evaluated sampling methods, seasonality and diversity of the hemerobiids associated to Coffea arabica L. cv. Obatã over a one-year period in Cravinhos, São Paulo, Brazil. The collecting methods were: sweeping net, light trap and Mõericke trap. 489 hemerobiids belonging to four genera, were collected: Nusalala (231 individuals / 47.2 percent of the hemerobiids collected), Megalomus (110 / 22.5 percent), Hemerobius (104 / 21.3 percent) and Sympherobius (44 / 9 percent). The sweeping net seems to be the most efficient method of sampling to capture Hemerobiidae and the Mõericke trap presented the higher value of diversity (H'= 0,56) and equitability (J= 0,93). The hemerobiids were recorded in the area along the entire year. The highest abundance occurred from August to March (end of winter, spring and summer) and the population peak was in January (mid-summer). Megalomus presented positive and significant correlations (p< 0.05) with the rainfall and maximum and minimum temperatures; Nusalala with the maximum and minimum temperatures and Sympherobius only with the maximum temperature.
