AbstractTwo Early Eocene hemerobiid species from the Okanagan Highland deposits of western North America are described: Wesmaelius mathewesisp. nov. (Quilchena, British Columbia, Canada) and Cretomerobius wehrisp. nov. (Republic, Washington, United States of America.). A poorly preserved specimen, possibly Hemerobiidae (Driftwood Canyon, British Columbia, Canada) is discussed. The systematic position of the genus Cretomerobius within the Hemerobiidae is unclear, but it appears to belong within (or possibly as the sister group to) the poorly differentiated Drepanacrinae–Megalominae–Drepanepteryginae grade of subfamilies. Wesmaelius mathewesi is the first fossil species to be assigned, although with some uncertainty, to this otherwise speciose and widely distributed extant genus. It also represents the oldest known material of the subfamily Hemerobiinae. Meso hemerobius jeholensis Ping is removed from the Hemerobiidae and treated as Neuroptera incertae sedis.

A fossil larva of Hemerobiidae (Neuroptera) is recorded for the first time from Baltic amber. The subfamilial and generic affinities of this larva are discussed. It is assumed that it may belong to Prolachlanius resinatus, the most common hemerobiid species from the Eocene Baltic amber forest. An updated list of extant species of Hemerobiidae with described larvae is provided.

AbstractA new genus and species, Adelphohemerobius enigmaramus, is described from Chile and assigned to a new subfamily, Adelphohemerobiinae, of the neuropterous family Hemerobiidae (brown lacewings). A cladistic analysis of morphological data derived from the unique female holotype of A. enigmaramus supports the conclusion that it represents the sister-group of the family Hemerobiidae sensu Oswald (1993a). The holotype of A. enigmaramus is interpreted to be the first non-teratological hemerobiid specimen known to possess a single 'radial sector', i.e., only the true ancestral Rs.

Full textAbstract:
Proneuronema sidorchukae sp. nov. (Neuroptera: Hemerobiidae: Drepanepteryginae) is described from the late Eocene Rovno amber, Ukraine. It is most similar to P. minor from Baltic amber, but easily distinguished from it by some crossveins in the third gradate series of the forewing broadly margined with dark brown, the proximal part of the costal space narrower, and proximal subcostal veinlets more oblique. The new species is the smallest known of the genus, with a forewing length of 5.9 mm. Rovno amber hemerobiids show a tendency to decrease in size compared to congeneric or conspecific specimens from Baltic amber. The morphology and terminology of the mesonotum in Hemerobiidae is discussed.

ABSTRACT Hemerobiidae (Insecta, Neuroptera) is a cosmopolitan clade that comprises about 600 described species distributed into 26 genera. Since the publication of revisions to Hemerobius, Megalomus, Nusalala and Nomerobius, new records have been added in literature and taxonomic modifications have occurred at the genus level. The aim of this study was to update a checklist of Hemerobiidae species from Brazil and of specimens deposited at Coleção de Invertebrados do Instituto Nacional de Pesquisa da Amazônia (INPA), Manaus, Brazil; in order to summarize the geographical data of species in Brazilian states and in the Neotropical Region and to present new distributional data. The INPA collection holds 19 nominal species (55.2% of the all specimens identified at species level) of hemerobiids into eight genera and six subfamilies, mainly from the Neotropical Region; the remaining studied specimens were identified to the genus level. Megalomus marginatus is reported for the first time in Brazil and Nusalala dispar in Ecuador. Moreover, ten new records for the Brazilian states are presented: two to Nusalala tessellata and Hemerobius, and one each to Megalomus impudicus, Notiobiella maculata, Sympherobius ariasi, Megalomus, Nusalala and Sympherobius.

Eighteen species of Hemerobiidae are recorded from New Guinea, and keys provided for their separation. They represent six genera: Notiobiella (five spp.), Psectra (four), Zachobiella (one), Megalomina (one), Hemerobius (three) and Micromus (four). Nine species are described as new (three Notiobiella, three Psectra, two Hemerobius and one Micromus) and a further two singletons noted as possibly new but not named. Few species appear to be common, and five (possibly six) occur also in Australia.

Hemerobiídeos possuem importância em programas de controle biológico de pragas agrícolas, pois se alimentam de artrópodes pragas associados às diversas culturas, porém dados de sua biologia e distribuição ainda são escassos. Devido à sua importância e a escassez de dados, o presente estudo teve como objetivo realizar um levantamento de espécies de Hemerobiidae em frutíferas submetidas a sistemas de cultivo orgânico e convencional da região de Avaré, São Paulo, com o intuito de auxiliar futuros programas de controle biológico que possam utilizar hemerobiídeos como agente predador controlador. Durante um ano realizaram-se coletas com armadilhas tipo McPhail e atrativo de suco de manga em espécies de frutíferas. No total coletaram-se 22 espécimes de quatro espécies de três gêneros de Hemerobiidae, 16 espécimes de Hemerobius domingensis Banks, 1941, Megalomus impudicus (Gerstaecker, 1888), Megalomus rafaeli Penny & Monserrat, 1985 e Nusalala tessellata (Gerstaecker, 1888) foram coletadas em frutíferas submetidas ao sistema de cultivo orgânico, e seis espécimes de M. rafaeli e N. tessellata foram coletados em frutíferas submetidas ao sistema de cultivo convencional. A maior diversidade de Hemerobiidae foi observada em frutíferas submetidas ao sistema de cultivo orgânico, provavelmente devido a sua maior diversidade vegetacional e ao não uso de produtos fitossanitários.

A população de Hemerobiidae (Neuroptera) associada a Coffea arabica L. foi amostrada em Cravinhos e Monte Mor, SP, Brasil. Em Cravinhos, entre maio/2005 e abril/2007, foram realizadas coletas semanais através de rede de varredura e armadilhas de Moericke e luminosa; em Monte Mor, entre agosto/2005 e março/2006, avaliou-se o efeito da coloração de armadilhas de Moericke e sua altura em relação ao solo para a amostragem de hemerobiídeos. As amostragens realizadas em Monte Mor com as armadilhas de Moericke de diferentes cores e alturas em relação ao solo não apresentaram diferença significativa (p< 0,05) para o total de hemerobiídeos coletados (129 espécimes/4 espécies). Em Cravinhos foram obtidos 882 exemplares de sete espécies: 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 rede de varredura e a armadilha de Moericke foram as mais eficientes. As maiores freqüências foram registradas no inverno/2005, nas primaveras e nos verões e o pico populacional ocorreu em novembro/2006. A armadilha luminosa foi o método de amostragem que apresentou os maiores valores de diversidade (H’= 0,66) e de equitabilidade (J= 0,78). Três espécies foram constantes: H. bolivari (C= 79,2%), Me. impudicus (C= 87,5%) e Nu. tessellata (C= 95,8%). Nu. tessellata e Me. impudicus apresentaram correlações positivas e significativas (p< 0,05) com Coccus sp. (Hemiptera, Coccidae) e com a precipitação pluviométrica e as temperaturas máxima e mínima; o mesmo ocorreu para H. bolivari com Oligonychus ilicis (Acari, Tetranychidae) e a temperatura mínima, para S. miranda com as temperaturas máxima e mínima e para Me. rafaeli com larvas de Leucoptera coffeella (Lepidoptera, Lyonetiidae).
The hemerobiids associated to Coffea arabica L. were sampled in Cravinhos and Monte Mor, São Paulo, Brazil. In Cravinhos, weekly and from May/2005 to April/2007, were realized collects by using sweeping net, light trap and Moericke trap; in Monte Mor, between August/2005 and March/2006, were evaluated the coloration and height in relation to the ground level of Moericke traps to sample Hemerobiidae. In Monte Mor, the results showed that the color and height of the traps did not present differences in regard to the evaluation of the diversity of the population of hemerobiids (129 individuals / 4 species). A total of 882 hemerobiids belonging to seven species were collected in Cravinhos: 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%), Sympherobius ariasi (6 / 0.7%) and Nomerobius psychodoides (3 / 0.3%). The Moericke trap and sweeping net were the most efficient methods to capture Hemerobiidae. The highest abundance occurred in the winter/2005 and in the two spring and summer seasons studied. The peak of occurrence was in November/2006. The light trap was the sampling method that presented the highest indexes of diversity (H’= 0.66) and equitability (J= 0.78). Three species were constants: H. bolivari (C= 79.2%), Me. impudicus (C= 87.5%) and Nu. tessellata (C= 95.8%). Nu. tessellata and Me. impudicus presented positive and significant correlations (p< 0.05) with Coccus sp. (Hemiptera, Coccidae) and maxim and minim temperatures and rainfall; the same occurred to H. bolivari with Oligonychus ilicis (Acari, Tetranychidae) and minim temperature, to S. miranda with the maxim and minim temperatures and to Me. rafaeli with Leucoptera coffeella (Lepidoptera, Lyonetiidae) larvae.

Full textAbstract:
The Tasmanian lacewing (Micromus tasmaniae Walker) is one of the most common aphid predators occurring in lucerne crops in New Zealand. A comparison of sampling techniques, and the output from a simulation model, suggest that the abundance of this lacewing may have been significantly underestimated in the past. Although the occurrence of aphid predators was erratic M. tasmaniae occurred more often and in far greater numbers (up to 100 m⁻²) than any other predator species. A simulation model for lacewing development in the field indicated that the large adult populations which occurred could be accounted for on the basis of reproductive recruitment. Independent evidence that immigration was not involved in the occurrence of these large populations was gathered using directional flight traps around the field perimeter. The major factors influencing lacewing population dynamics were the availability of aphid prey and, in the autumn, parasitism. Otherwise, survival of all life-histoty stages was high with no evidence of egg or larval cannibalism. Several instances of high lacewing mortality were identified by the model and the lack of any obvious cause for these highlights inadequacies in the understanding of lacewing bionomics. The model, which used a linear relationship (day-degrees) between development and temperature, was incapable of accurately predicting lacewing emergence under field temperatures which fluctuated outside the linear region of the development rate curve. Temperature thresholds and thermal requirements estimated under fluctuating temperatures similar to those in the field produced almost identical model output to those estimated under constant temperatures in the laboratory. Prey species was capable of influencing the rate of lacewing development. M. tasmaniae has the attributes necessary to produce large populations in the short time available between lucerne harvests. The asymptote of the functional response curve is low but the efficiency at converting aphids to eggs is high. Therefore, the lacewing is able to attain maximun reproductive output at low prey densities. A low temperature threshold for development (4-5° C), rapid development and short preoviposition period results in a short generation time (49 days at 15° C). Long adult life, high fecundity and the absence of any form of estivation or diapause, results in complete overlap of generations and multiple generations per year. M. tasmaniae's role as an aphid predator is restricted by its low appetite for prey and by the lucerne management regime currently practiced in New Zealand. Because it consumes relatively few aphids per day the lacewing's ability to destroy large aphid populations is limited. However, this may be offset by its ability to attack aphids early in the aphid population growth phase, and by the large numbers of lacewings which may occur. Under the present lucerne management schemes the large lacewing populations which do occur are forced out of the fields, or die, following harvest. A number of management options for increasing the lacewings impact as an aphid predator are briefly discussed.

Arthropod species that have the potential to damage crops are food resources for communities of predators and parasitoids. From an agronomic perspective these species are pests and biocontrol agents respectively, and the relationships between them can be important determinants of crop yield and quality. The impact of biocontrol agents on pest populations may depend on the availability of other food resources in the agroecosystem. A scarcity of such resources may limit biological control and altering agroecosystem management to alleviate this limitation could contribute to pest management. This is a tactic of ‘conservation biological control’ and includes the provision of flowers for species that consume prey as larvae but require floral resources in their adult stage. The use of flowers for pest management requires an understanding of the interactions between the flowers, pests, biocontrol agents and non-target species. Without this, attempts to enhance biological control might be ineffective or detrimental. This thesis develops our understanding in two areas which have received relatively little attention: the role of flowers in biological control by true omnivores, and the implications of flower use by fourth-trophic-level life-history omnivores. The species studied were the lacewing Micromus tasmaniae and its parasitoid Anacharis zealandica. Buckwheat flowers Fagopyrum esculentum provided floral resources and aphids Acyrthosiphon pisum served as prey. Laboratory experiments with M. tasmaniae demonstrated that although prey were required for reproduction, providing flowers increased survival and oviposition when prey abundance was low. Flowers also decreased prey consumption by the adult lacewings. These experiments therefore revealed the potential for flowers to either enhance or disrupt biological control by M. tasmaniae. Adult M. tasmaniae were collected from a crop containing a strip of flowers. Analyses to determine the presence of prey and pollen in their digestive tracts suggested that predation was more frequent than foraging in flowers. It was concluded that the flower strip probably did not affect biological control by lacewings in that field, but flowers could be significant in other situations. The lifetime fecundity of A. zealandica was greatly increased by the presence of flowers in the laboratory. Providing flowers therefore has the potential to increase parasitism of M. tasmaniae and so disrupt biological control. A. zealandica was also studied in a crop containing a flower strip. Rubidium-marking was used to investigate nectar-feeding and dispersal from the flowers. In addition, the parasitoids’ sugar compositions were determined by HPLC and used to infer feeding histories. Although further work is required to develop the use of these techniques in this system, the results suggested that A. zealandica did not exploit the flower strip. The sugar profiles suggested that honeydew had been consumed by many of the parasitoids. A simulation model was developed to explore the dynamics of aphid, lacewing and parasitoid populations with and without flowers. This suggested that if M. tasmaniae and A. zealandica responded to flowers as in the laboratory, flowers would only have a small effect on biological control within a single period of a lucerne cutting cycle. When parasitoids were present, the direct beneficial effect of flowers on the lacewing population was outweighed by increased parasitism, reducing the potential for biological control in future crops. The results presented in this thesis exemplify the complex interactions that may occur as a consequence of providing floral resources in agroecosystems and re-affirm the need for agroecology to inform the development of sustainable pest management techniques.

Dissertação de Mestrado - Biotecnologia em Controlo Biológico.Para o arquipélago dos Açores estão referenciadas duas famílias da ordem Neuroptera: Chrysopidae (green lacewings) e Hemerobiidae (brown lacewings). Estes insectos têm potencial para serem eficazes agentes de controlo biológico, predando uma grande variedade de insectos, incluindo algumas das mais importantes pragas do mundo em campos agrícolas e hortícolas. O uso efectivo destes neuropteros como agentes de controlo biológico exige o conhecimento dos seus padrões de sazonalidade, em particular para avaliar se a sincronia entre um dado predador e a respectiva presa é adequada. É também importante conhecer a dinâmica espacial e a escolha de habitats de forma a diferenciar a sua qualidade e realizar uma gestão eficaz. Amostragens da fauna de Neuropteros na Ilha de S. Miguel (Açores) foram realizadas ao longo de um ano, em seis habitats diferentes: Laurissilva, floresta exótica, pastagens, culturas agrícolas, jardins e pomares. Calcularam-se os seguintes parâmetros ecológicos: abundância relativa; riqueza específica; dominância, diversidade e heterogeneidade de cada habitat; foi ainda analisada a composição da comunidade de cada habitat, bem como a sazonalidade de cada família e espécies mais representativas. Concluímos que, quatro das espécies existentes nos Açores têm potencial para serem usadas em campos agrícolas, pomares e jardins do arquipélago; duas espécies são extremamente raras, e uma espécie não foi encontrada. A sazonalidade das populações de Neuroptera não foi a esperada, provavelmente devido a condições climáticas alteradas. Uma pesquisa de longo prazo desta característica nos habitats alvo, em conjunto com o estudo da sazonalidade da presa, é pois aconselhada.
ABSTRACT: Among the Neuroptera order, two families, Chrysopidae (green lacewings) and Hemerobiidae (brown lacewings) are reported to the Azores archipelago. Lacewings are known to be effective biological control agents, preying upon a large range of insects, including some of the world´s most important agricultural and horticultural pests. The effective use of lacewings as biological control agents requires the knowledge of their seasonality patterns, particularly to assess whether the synchrony between a given predator and its prey, is adequate; also the spatial dynamics and habitat choice, is important to differentiate between habitats of different quality for effective management. Surveys of the Neuroptera fauna of S. Miguel Island (Azores) were performed along one year, in six different habitats: Laurissilva forest, exotic forest, pastures, agricultural crops, gardens and orchards. The relative abundance, species richness, species dominance, diversity and heterogeneity of each habitat, were calculated; community composition for each habitat was also assessed, as well as the seasonality for each Neuroptera family and most representative species. We concluded that, four of the existing species in the Azores have the potential to be used in crops, orchards and gardens of the archipelago; two species are extremely rare and one species was not found. The seasonality of the Neuroptera populations was not the expected one, probably due to altered climate conditions. A long-term survey targeting this feature in the studied habitats, along with the assessment of the prey´s seasonality, is advised.
