Pentatomoidea (Hemiptera: Pentatomidae, Scutelleridae) Associated With The Dioecious Shrub Florida Rosemary, Ceratiola Ericoides (Ericaceae), A. G. Wheeler Jr.

The Great Lakes Entomologist

Florida rosemary (Ceratiola ericoides), an ericaceous shrub with needlelike leaves, is characteristic of Florida scrubs and certain other xeric plant communities of well-drained sands. The plant is dioecious, its inconspicuous male and female flowers borne on separate individuals. From 2003 to 2012 (mainly 2007–2012), rosemary was sampled periodically (with all months included at least once during the period) in sand ridges of peninsular Florida and two riverine dunes in southeastern Georgia. Branches of male and female plants were tapped separately into a beating net. Sampling during the final three years was female-plant-biased to facilitate work on fruit- and seed-feeding …

The Great Lakes Entomologist

Litter-inhabiting Collembola and mites were sampled using pitfall traps over a twelve-month period from four sub-communities within a 100-acre (40-ha) oak-woodland complex in northern Cook County, Illinois. Sampled locations included four areas where future ecological restoration was planned (mesic woodland, dry-mesic woodland, mesic upland forest, and buckthorn-dominated savanna) and a mesic woodland control that would not be restored. Fifty-eight mite and 30 Collembola taxa were identified out of 5,308 and 190,402 individuals trapped, respectively. There was a significant positive relationship between litter mass and both mite diversity and the ratio of Oribatida to Prostigmata and a significant negative relationship between …

A New Species Of Aphis In Minnesota (Hemiptera: Aphididae) On Narrow-Leaved Purple Coneflower, Echinacea Angustifolia, D. M. Lagos, D. J. Voegtlin

The Great Lakes Entomologist

Aphis echinaceae, n. sp. is described from specimens collected in Douglas County, Minnesota, on Echinacea angustifolia (DC.). The aphid is illustrated with biometric data for alate and apterous vivipara. Its short cauda and siphunculi, and presence of secondary sensoria on antennal segments III, IV, and V in both morphs makes this Aphis morphologically similar to A. debilicornis (Gillette and Palmer), A. lugentis Williams and A. caliginosa Hottes and Frison, and root feeding aphids of the subgenus Pseudoprotaphis Kadyrbekov and genus Protaphis Börner. A diagnosis is provided.

Effects Of Pitfall Trap Preservative On Collections Of Carabid Beetles (Coleoptera: Carabidae), Kenneth W. Mccravy, Jason E. Willand

The Great Lakes Entomologist

Effects of six pitfall trap preservatives (5% acetic acid solution, distilled water, 70% ethanol, 50% ethylene glycol solution, 50% propylene glycol solution, and 10% saline solution) on collections of carabid beetles (Coleoptera: Carabidae) were studied in a west-central Illinois deciduous forest from May to October 2005. A total of 819 carabids, representing 33 species and 19 genera, were collected. Saline produced significantly fewer captures than did acetic acid, ethanol, ethylene glycol, and propylene glycol, while distilled water produced significantly fewer captures than did acetic acid. Significant associations between numbers of captures and treatment were seen in four species: Amphasia interstitialis …

Why Are There So Few Insect Predators Of Nuts Of American Beech (Fagus Grandifolia)?, Charles E. Williams

The Great Lakes Entomologist

American beech, Fagus grandifolia Ehrh., is a common nut-bearing tree of eastern North America. Compared to other North American nut-bearing tree species of comparable geographic range, the nut-infesting insect fauna of American beech is species-poor: only the filbertworn, Cydia latiferreana (Wlsm.) (Lepidoptera: Tortricidae), infests nuts of American beech. Why are there so few insect predators of nuts of American beech? Using data from published studies, I explore two hypotheses that may help to explain the species-poor nut-infesting insect fauna of American beech. First, might chemical defense of beechnuts, and/ or low nutritional value, restrict the number of insect predators that …

A Friend Unmasked: Notes On Chauliognathus Pensylvanicus (Coleoptera: Cantharidae) And The Nature Of Natural History, Andrew H. Williams

The Great Lakes Entomologist

Data from field observations from 1992 through 2006 and from museum specimens of adult Chauliognathus pensylvanicus (DeGeer) from Wisconsin are presented here, with information from the literature. Beetles were found using flowers of 183 species in 29 families growing outside cultivation in Wisconsin and in every Wisconsin county.

Richness And Abundance Of Carabidae And Staphylinidae (Coleoptera), In Northeastern Dairy Pastures Under Intensive Grazing, R. A. Byers, G. M. Barker, R. L. Davidson, E. R. Hoebeke, M A. Sanderson

The Great Lakes Entomologist

Dairy cattle has become popular to dairy farmers in the Northeast looking for management schemes to cut production costs. Carabidae (ground beetles) and Staphylinidae (rove beetles) are indicators of habitat disturbances, such as drainage of wetlands, or grassland for grazing animals, and their monitoring could provide one measure of ecosystem sustainability if intensive management systems expand or intensify in the future. Our objective was assess the abundance and species richness of these two beetle families under intensive grazing throughout Pennsylvania, southern New York and Vermont. We collected 4365 ground beetles (83 species) and 4,027 rove beetles (79 species) by pitfall …

Dispersal And Re-Capture Of Marked, Overwintering Tomicus Piniperda (Coleoptera: Scolytidae) From Scotch Pine Bolts, A. V. Barak, D. Mcgrevy, G. Tokaya

The Great Lakes Entomologist

The pine shoot beetle (PSB), Tomicus piniperda is a recently established exotic pest of live pine in the southern Great Lakes of the U.S. and Canada. Scotch pine, Pinus sylvestris L. is the most susceptible pine species, but the adult also attacks several other North American species of Pinus. This research investigated the dispersal behavior of beetles emerging from overwintering sites to aid in the development of effective monitoring and management practices. Scotch pine logs with overwintering PSB were sprayed with fluorescent pigments to mark dispersing beetles. These logs were placed in piles in the centers of three circular …

Seasonal Shoot-Feeding By Tomicus Piniperda (Coleoptera: Scolytidae) In Michigan, Robert A. Haack, Robert K. Lawrence, George C. Heaton

The Great Lakes Entomologist

Seasonal shoot-feeding by Tomicus piniperda (L.) was monitored at 2­ week intervals on 15 Scotch pine, Pinus sylvestris L., trees from 8 April through 16 November 1994 in southern Michigan. All shoots that showed evidence of T. piniperda attack were removed every two weeks. In 1994, initial spring flight of T. piniperda began on 22 March. At least two live T. piniperda adults were found on the 15 trees on each sampling date from 8 April through 1 November 1994. In addition, at least one freshly attacked, beetle- free shoot was found on each sampling date except for 1 November. …

Tomicus Piniperda (Coleoptera: Scolytidae): Is Shoot Feeding Required For Reproductive Maturation?, Therese M. Poland, Robert A. Haack

The Great Lakes Entomologist

The pine shoot beetle, Tomicus piniperda (Coleoptera: Scolytidae), is a univoltine pest of pine in its native range of Europe and Asia. Tomicus piniperda is now widely established in the Great Lakes region and poses a potentially significant threat to other pine-producing areas in North America. An unusual aspect of the life history of T. piniperda is the extended period of maturation-feeding that takes place in the shoots of living pine trees and subsequent overwintering before adults reproduce the following year. We investigated the extent to which shoot-feeding is required by newly-emerged T. piniperda before introduction into Scotch pine (Pinus …

Habitat Characterization Of Five Rare Insects In Michigan (Lepidoptera: Hesperiidae, Riodinidae, Satyridae; Homoptera: Cercopidae), Keith S. Summerville, Christopher A. Clampitt

The Great Lakes Entomologist

Over 80 species of insects are listed as endangered, threatened, or special concern under Michigan's endangered species act. For the majority of these species, detailed habitat information is scant or difficult to interpret. We describe the habitat of five insect species that are considered rare in Michigan: Lepyronia angulifera (Cercopidae), Prosapia ignipectus (Cercopidae), Oarisma poweshiek (Hesperiidae), Calephelis mutica (Riodinidae), and Neonympha mitchellii mitchellii (Satyridae). Populations of each species were only found within a fraction of the plant communities deemed suitable based upon previous literature. Furthermore, individuals of each species were observed to be closely affiliated with just a few vegetation …

Sex Ratio And Sexual Dimorphism In Formica Exsectoides, The Allegheny Mound Ant (Hymenoptera: Formicidae), H. C. Rowe, C. M. Bristow

The Great Lakes Entomologist

We excavated 66 mounds from 6 populations of Formica exsectoides in Michigan jack pine, collecting sexual caste pupae for sex ratio estimates and measurement of dimorphism. Reproductive caste brood was present in only 37 ofthe 66 mounds, and presence of reproductive caste brood was associated with larger mound surface area. Females were heavier than males, but did not differ from males in energy density. Sexes did not differ in timing or rate of development. Sex ratio estimates based on individual mounds ranged from 1.0 (all male) to 0.08 (female·biased). Four of the six study populations were strongly male·biased, while sex …

University of Nebraska State Museum: Mammalogy Papers

Conclusions

It is our contention that Thomas Say, Titian Peale, Edwin James, and their colleagues of the Stephen Long Expedition of 1819–1820 were heavily engaged in scientific research, which took the form of the first biodiversity inventory undertaken in the United States. This accomplishment has been overlooked both by biologists and historians, but it should rank among the most significant accomplishments of the expedition. The results of this inventory continue to inform us today about environmental, faunal, and floral changes along the Missouri River in an area that is known to be an ecotone between the deciduous forests of the …

Review: Application Of Tick Control Technologies For Blacklegged, Lone Star, And American Dog Ticks, Alexis White, Holly Gaff

Biological Sciences Faculty Publications

Tick population control technologies have been studied for several decades but no method is successful in all situations. The success of each technology depends on tick species identity and abundance, host species identity and abundance, phenology of both ticks and hosts, geographic region, and a multitude of other factors. Here we review current technologies, presenting an overview of each and its effect on three common tick species in the eastern United States: blacklegged ticks (Ixodes scapularis (Say; Ixodida: Ixodidae)), lone star ticks (Amblyomma americanum (Linnaeus; Ixodida: Ixodidae)), and American dog ticks (Dermacentor variabilis (Say; Ixodida: Ixodidae)). Moreover, …

Tomicus Piniperda (Coleoptera: Scolytidae) Reproduction And Behavior On Scotch Pine Christmas Trees Taken Indoors, Robert A. Haack, Robert K. Lawrence

The Great Lakes Entomologist

Tomicus piniperda, the pine shoot beetle, is an exotic insect that was first found in North America in 1992. A federal quarantine currently restricts movement of pine products, including Christmas trees, from infested to uninfested counties. We conducted a study to determine if T. piniperda would re- produce in Christmas trees that were cut and taken indoors during the Christmas season. Twelve Scotch pine, Pinus sylvestris, Christmas trees infested with overwintering T. piniperda beetles were cut in Indiana in early December 1993 and taken to Michigan. Four trees were dissected immediately, while the other 8 trees were taken …

A survey was conducted to identify the types and relative abundance of predatory arthropods associated with Panonychus ulmi in 21 Ohio apple orchards. Mite populations were sampled by leaf brushing, and insects and spiders were sampled by limb jarring. A state-wide survey was conducted in early July and in late August 1992, and five blocks were evaluated periodically from May until August 1992 at one farm in central Ohio. Predatory mites were detected in only 27% of the blocks surveyed in early July, but in 74% of the blocks surveyed in late August. The ratio of predatory mites to motile …

Differential Shoot Feeding By Adult Tomicus Piniperda (Coleoptera: Scolytidae) In Mixed Stands Of Native And Introduced Pines In Indiana., Clifford S. Sadof, Robert D. Waltz, Charles D. Kellam

The Great Lakes Entomologist

The larger pine shoot beetle Tomicus piniperda, a native bark beetle of Europe and Asia, was found in North American Christmas tree plantations in 1992 in Ohio. Subsequent surveys found it in six U.S. states and in one Canadian province. The first natural area where Tomicus was found to be established was at the Indiana Dunes State Park, in northwestern Indiana near the Lake Michigan shoreline. Pine stands were surveyed for fallen shoots to determine the extent and range of shoot feeding in the park. Within the study area adult Tomicus fed on the shoots of all native pines …

Field Investigations On The American Dog Tick, Dermacentor Variabilis, In Northwest Ohio (Acari: Ixodidae), Kelly M. Micher, C. Lee Rockett

The Great Lakes Entomologist

Ecological investigations on the American dog tick, Dermacentor variabilis, were conducted in two metroparks located in Lucas County, Ohio. Adult tick surveys were conducted in 1989 and 1990. For both years, adult tick activity began in late April, and adult ticks were most abundant from early May to mid-June. Observed activity had ceased by early August, producing a unimodal pattern of activity. Sunny days with temperatures between 24 ° and 32°C were most conducive to adult tick activity, and adult ticks were most abundant on grass trails and in meadows. Using nest boxes inhabited by white-footed mice, immature tick …

W. Clarke, C. Capdevielle Dulac, J. Obonyo, R. Benoist, J. Gauthier, P. A. Calatayud, J. F. Silvain, B. P. Le Ru

All Peer-Reviewed Publications

This review covers nearly 20 years of studies on the ecology, physiology and genetics of the Hymenoptera Cotesia sesamiae, an African parasitoid of Lepidoptera that reduces populations of common maize borers in East and South Africa. The first part of the review presents studies based on sampling of C. sesamiae from maize crops in Kenya. From this agrosystem including one host plant and three main host borer species, studies revealed two genetically differentiated populations of C. sesamiae species adapted to their local host community, and showed that their differentiation involved the joint evolution of virulence genes and sensory mechanisms of …

The Parasitoid Complex Of Forest Tent Caterpillar, Malacosoma Disstria (Lepidoptera: Lasiocampidae), In Eastern Wyoming Shelterbelts, G. A. Knight, R. J. Lavigne, M. G. Pogue

The Great Lakes Entomologist

A parasitoid complex affecting the forest tent caterpillar, Malacosoma disstria, was investigated during 1978-79 in shelterbelts in eastern Wyoming. Egg parasitoids included five species: Ablerus clisiocampae, Ooencyrtus clisiocampae, Telenomus clisiocampae, Tetrastichus sp. 1 and Telenomus sp. Thirteen hymenopterous species and five dipterous species were reared from larvae and pupae of the forest tent caterpillar. The most common 5th-instar larval parasitoids were the tachinid flies, Lespesia archippivora and Archytas lateralis. Of the pupal parasitoids reared, 640/0 were Diptera and 36% were Hymenoptera. Four previously unrecorded parasitoids of M. disstria were reared: Cotesia alalantae, Macrocentrus irridescens, Pimpla sanguinipes erythropus, …

The Insects Of Treeholes Of Northern Indiana With Special Reference To Megaselia Scalaris (Diptera: Phoridae) And Spilomyia Longicornis (Diptera: Syrphidae), Robert S. Copeland

The Great Lakes Entomologist

The aquatic insect community of treeholes in northern Indiana was surveyed from 1983-1986. Twenty-three species, representing three orders and nine families, were found. Megaselia scalaris (Diptera: Phoridae) was collected on several occasions from rotholes, the first member of this family from treeholes. Examination of puparia of Spilomyia longicornis (Diptera: Syrphidae) indicated that the larva of this species has been previously described, but incorrectly associated with the genus Xylata.
