TL;DR: The hemerobiid genitalic structure previously termed the "parameres" is here considered a unique evolutionary novelty of the family, and renamed the parabaculum, facilitating comparative analysis of this complex sclerite.
Abstract: -The extant world genera of the family Hemerobiidae are revised; and the literature on fossil hemerobiids is reviewed. A key is provided to the 25 extant genera recognized. An intergeneric cladistic analysis utilizing 107 characters, 24 ingroup genera, and 3 outgroup species provides a basis for (1) justifying the holophyly of the family, (2) recognizing holophyletic subgroups within the family, (3) proposing a new nine-subfamily classification of the family, and (4) identifying putative synapomorphies for nearly all recognized named taxa. Traits used in the cladistic analysis include characters from the head, forewing, and male and female terminalia. The biogeographic patterns exhibited within the family are discussed in light of the cladistic classification. For each genus, a synonymical listing, a differential diagnosis, a list of proposed synapomorphies, and notes on distribution and included species are given. To the extent possible from the material available for study, representative forewings, hind wings, and several aspects of the male and female terminalia, are illustrated for each genus. Phylogenetically important character complexes are analyzed in the comparative framework of the familial classification. The hemerobiid genitalic structure previously termed the \"parameres\" is here considered a unique evolutionary novelty of the family, and renamed the parabaculum. This structure is not a homologue of the \"parameres\" (=9th gonocoxites sensu Adams) of other neuropterous families. A new terminology is proposed for the putatively homologous regions of the gonarcus, facilitating comparative analysis of this complex sclerite.
TL;DR: It is unlikely that established predators are exhibiting any significant control onAdelgid populations because of the low densities of predators that were encountered at a time when adelgids were abundant, therefore, controlled releases of non-native predators into these sites should be considered.
Abstract: There has been little research conducted on the effects of native or established predators on populations of the hemlock woolly adelgid, Adelges tsugae Annand. This study used field surveys and cage exclusion experiments to examine the relationship between established predators and A. tsugae in the southeastern United States. Predators were collected in very low densities in both years. Harmonia axyridis Pallas (Coleoptera: Coccinellidae), lacewings (Neuroptera: Chrysopidae and Hemerobiidae), and gall gnats (Diptera: Cecidomyiidae) represented 81% of the total predators collected in 1998. Cage exclusion experiments revealed no significant predator effects in all three sites in 1997 and 1998. It is unlikely that established predators are exhibiting any significant control on adelgid populations because of the low densities of predators that were encountered at a time when adelgids were abundant. Therefore, controlled releases of non-native predators into these sites should be considered.
TL;DR: The Asian citrus psyllid, Diaphorina citri, recently invaded the citrus-producing regions of Florida, reaching the northern limits of commercial production in summer of 2001, and preliminary observations indicate a wide range of natural enemies attacking juvenile stages of D. citri.
Abstract: The Asian citrus psyllid, Diaphorina citri, recently invaded the citrus-producing regions of Florida, reaching the northern limits of commercial production in summer of 2001. Preliminary observations indicate a wide rangeof natural enemies attacking juvenile stages of D. citri. The exotic parasitoid Tamarixiu radiata (Hymenoptera: Eulophidae) was released in previous years and has established, but is not a significant source of mortality for D. citri at present. The primary sources of mortality for juvenile psyllids are two coccinellid species, Olla v-nigrum and Harmonia axyridis. Both species complete development successfully on an exclusive diet of D. citri. Other ladybeetles completing development on D. citri include Curinus coeruleus, Cycloneda sanguinea, and Exochomus childreni childreni. Other predators observed attacking D. citri in Florida include hunting spiders (Aranae: Anyphaenidae, Clubionidae, Oxyopidae, and Salticidae), lacewings (Neuroptera: Chrysopidae, Hemerobiidae), hoverflies (Diptera: Syrphidae), and predatory bugs (Hemiptera: Anthocoridae).
TL;DR: The present paper summarizes information on biology and ecology of these three most important Neuroptera families, followed by a description of Neuropteran communities found in different natural and semi-natural ecosystems, with special reference to agroecosystems.
TL;DR: A new genus and two new species of Hemerobiidae (Neuroptera) are described from the late Eocene Baltic amber, and some of their venational abnormalities (anomalies) may have phylogenetic implications.
Abstract: A new genus and two new species of Hemerobiidae (Neuroptera) are described from the late Eocene Baltic amber, ie, Proneuronema gradatum gen et sp nov and P minor gen et sp nov Several Early Eocene species (mostly unnamed) from Europe and North America are also considered to belong to this genus, including Proneuronema wehri (Makarkin et al , 2003), comb nov The new genus is probably most closely related to the extant genus Neuronema McLachlan, 1869, and therefore assigned to Drepanepteryginae A critical review of Cenozoic taxa of the Megalomus -like hemerobiids is provided Prophlebonema Kruger, 1923 is considered as a new subjective synonym of Drepanepteryx Leach, 1815 Plesiorobius Klimaszewski et Kevan, 1986 from the Late Cretaceous is considered as belonging to Hemerobiidae It is noted that wing venation variability in species of Hemerobiidae (including these fossils) is high Some of their venational abnormalities (anomalies) may have phylogenetic implications
