Pennsylvania planthoppers (Hemiptera: Auchenorrhyncha: Fulgoroidea): relative abundance and incidental catch using novel trapping methods

We present an abundance-based checklist of Pennsylvania planthoppers (Hemiptera: Auchenorrhyncha: Fulgoroidea) compiled from available literature and 13,718 specimens. A substantial portion of the latter were bycatch from Lindgren funnel and panel traps intended to intercept wood-boring beetle species, and a directed survey for the spotted lanternfly (Lycorma delicatula (White)). The known planthopper fauna of Pennsylvania consists of 10 families, 54 genera and 139 species including 34 new state species records (and 12 new genera). In an attempt to assess the level of completeness of this survey, we compiled an abundance-based checklist of planthopper species found in states adjacent to Pennsylvania and found similar numbers of planthopper species for each state (viz. Delaware 138 species, Maryland 147, New Jersey 145, New York 162 and Ohio 126), but the cumulative species list is comprised of 240 planthopper species, suggesting that the inventory for Pennsylvania and all adjacent states may be substantially incomplete

Hemlock Woolly Adelgid (Hemiptera: Adelgidae) Management in Forest, Landscape, and Nursery Production

Hemlock woolly adelgid, Adelges tsugae (Annand) (Hemiptera: Adelgidae), has caused significant damage to both eastern [Tsuga canadensis (L.) Carrière] and Carolina hemlock (Tsuga caroliniana Englemann) (Pinales: Pinaceae) since it was first reported in the eastern United States. This adelgid is particularly damaging to these hemlock species due to a lack of co-evolved plant defenses and natural enemies able to suppress hemlock woolly adelgid populations. Management of hemlock woolly adelgid relies heavily on insecticides to prevent death of vulnerable trees. Biological control programs have released natural enemies of hemlock woolly adelgid to aid in control at the landscape level. Quarantine restrictions on hemlock are in place in some regions of the United States and Canada. These quarantines impact sales and shipment of hemlock trees from nurseries as well as other hemlock products. A review of insect biology, description of life stages, damage, management options, and quarantine restrictions for hemlock woolly adelgid is presented

The shrews of the Sorex dispar group : Sorex dispar Batchelder and Sorex gaspensis Anthony and Goodwin. American Museum novitates ; no. 2675

21 p. : ill., map ; 26 cm.Includes bibliographical references (p. 19-21)."The systematics and biology of the two shrews of the Sorex dispar group are described on the basis of a review of the literature and an examination of 247 museum specimens (224 Sorex dispar and 23 S. gaspensis). Sorex gaspensis is retained as a full species, and the species boundary between S.d. dispar and S.d. blitchi is shifted northward to the region of the Pennsylvania/Maryland/West Virginia borders. Information is also presented on the distribution, clinal variation, habitat preference, ecological niche, food habits, and reproduction of the two species"--P. [1]

ICHNOTAXONOMY AND PALEOENVIRONMENTAL ANALYSIS OF TRACE FOSSILS IN THE LATE DEVONIAN CATSKILL FORMATION, NORTH-CENTRAL PENNSYLVANIA, USA

The purpose of this thesis is to interpret the ichnotaxonomy, paleoenvironmental distribution, and paleoecological ramifications of trace fossils from the Frasnian to Famennian Catskill Formation (CF), north-central Pennsylvania, USA. The CF contains a suite of approximately 14 traces, 11 of which represent animal behavior, and 3 of which represent preservational styles and morphologies of plant roots. CF traces occur in paleosols and strata exhibiting no evidence of pedogenesis. Paleosol traces represent terraphilic to hydrophilic soil biota. Traces in strata with no evidence of pedogenesis represent aquatic organism behavior. Backfilled burrows--Beaconites antarcticus and B. barretti--represent dwelling and feeding by soil-dwelling arthropods. Rhizoliths represent shallow to deep rooting by plants with terraphilic to hydrophilic affinities. Backfilled burrows and rhizoliths form a characteristic ichnofabric that is superimposed on all pedogenically modified deposits. Lungfish estivation burrows--Hyperoeuthys teichonomos--are commonly superimposed on and subsequently overprinted by the dominant ichnofabric. Diplichnites gouldi is present in weakly developed paleosols and represents locomotion of an arthropod of unknown taxonomic affinity. In situ stump casts occur in paleosols of differing maturity and likely represent the life position of an arborescent plant. Camborygma eumekonomos and C. litonomos represent dwelling burrows of terraphilic to hydrophilic arthropods and are also overprinted by the dominant ichnopedofabric. Bivalve resting (Lockeia siliquaria), locomotion (Lockeia ornata), and escape traces, as well as fish swimming traces (Undichna multiloba), and Sagittichnus lincki--the resting trace of an unknown organism--represent aquatic organism behavior. The presence of terraphilic to hygrophilic and hydrophilic traces in CF paleosols indicates that Late Devonian soil organisms exhibited nearly as much behavioral complexity as Mesozoic to recent soil organisms. The abundance and degree of trace crosscutting increases in increasingly mature paleosols, indicating that CF paleosol ichnoassemblages, despite being controlled by paleohydrology, also represent ecological succession. Continental organisms are known exhibited behaviors that beneficially modify their environment (ecosystem engineering) by modulating resource flow paths (allogenic engineering) or modifying their bodies in ways that create new habitats for themselves (autogenic engineering). The idea that middle Paleozoic continental organisms were ecosystem engineers has not been examined. Our data suggest that the inception of allogenic ecosystem engineering in continental environments had occurred by the Late Devonian

The type genus is cited for each family-group name, the type species for each genus-group name, and the type locality for each species-group name. Where appropriate, all subgenera, subspecies, or synonyms are listed for each valid name. Annotated subsequent references are presented for all names. Distributional summaries are given for each valid taxon. Full bibliographic citations are in Part VII.
