          Abstract

          O objetivo deste trabalho foi avaliar a diversidade de Hemerobiidae (Neuroptera) em cafeeiros, e suas relações com Leucoptera coffeella, Coccus sp., Planococcus sp., Oligonychus ilicis, Brevipalpus phoenicis, Aphis spiraecola e Toxoptera aurantii. As amostragens foram realizadas em Cravinhos, SP, entre maio de 2005 e abril de 2007. Os hemerobiídeos foram coletados com rede de varredura, armadilha de Möricke e armadilhas luminosas e, para a amostragem das presas, foram coletadas folhas de cafeeiro. Foram obtidos 882 exemplares de hemerobiídeos: Nusalala tessellata (467 espécimes, 52,9% do total coletado), Hemerobius bolivari (153, 17,3%), Megalomus impudicus (114, 12,9%), Sympherobius miranda (109, 12,4%), Megalomus rafaeli (30, 3,4%), Sympherobius ariasi (6, 0,7%) e Nomerobius psychodoides (3, 0,3%). A ocorrência de Nusalala tessellata e M. impudicus foi correlacionada positivamente à de Coccus sp.; o mesmo fato ocorreu para M. rafaeli com lagartas de L. coffeella e A. spiraecola e para H. bolivari com O. ilicis. As correlações foram negativas e significativas entre as ocorrências de S. miranda e O. ilicis e entre as de N. tessellata e L. coffeella e O. ilicis. As correlações mostraram que os Hemerobiidae, predadores generalistas, foram favorecidos pelo constante suprimento de presas que ocorreram na cultura do café, no período estudado.

          The objective of this work was to evaluate the diversity of Hemerobiidae (Neuroptera) in coffee and its relationships with Leucoptera coffeella, Coccus sp., Planococcus sp., Oligonychus ilicis, Brevipalpus phoenicis, Aphis spiraecola and Toxoptera aurantii. The specimens were collected in Cravinhos, São Paulo state, Brazil, between May 2005 and April 2007. The hemerobiids were collected with sweeping nets, and light and Möricke traps. Coffee leaves were collected for prey sampling. A total of 882 hemerobiids were obtained: Nusalala tessellata (467 individuals, 52.9% of the hemerobiids collected), Hemerobius bolivari (153, 17.3%), Megalomus impudicus (114, 12.9%), Sympherobius miranda (109, 12.4%), Megalomus rafaeli (30, 3.4%), Sympherrobus ariasi (6, 0.7%) and Nomerobius psychodoides (3, 0.3%). Occurrence of Nusalala tessellata and M. impudicus showed significant positive correlations with Coccus sp. presence; the same fact occurred to M. rafaeli and L. coffeella larvae with A. spiraecola, and H. bolivari with O. ilicis. The correlations were negative and significant between occurrence of S. miranda and O. ilicis, and between N. tessellata and L. coffeella larvae and O. ilicis. The correlations showed that Hemerobiidae generalist predators were favored by the constant supply of preys that occurred during the study period in the coffee crop.
