Late Summer-Fall Solitary Wasp Fauna Of Central New York (Hymenoptera: Tiphiidae, Pompilidae, Sphecidae), Frank E. Kurczewski, Robert E. Acciavatti 2017 State University of New York College of Environmental Science and Forestry

Late Summer-Fall Solitary Wasp Fauna Of Central New York (Hymenoptera: Tiphiidae, Pompilidae, Sphecidae), Frank E. Kurczewski, Robert E. Acciavatti

The Great Lakes Entomologist

Eighty-one species of primarily ground-nesting solitary wasps belonging to the families Tiphiidae, Pompilidae and Sphecidae were observed, collected and identified from six sandy and gravelly study areas in Cayuga and Onondaga Counties, New York. The observations and collections were made 1 September-3 November 1966,1 September-l November 1967 and 13 September-29 October 1984, with some species (Ammophila urnaria, Diodontus franclemonti) nesting through the entire months of September and October. An attempt to associate extended flight season with overnight resting site, geographic distribution, taxonomic affinity and prey type is made, but only the association with prey type appears to have any ...

The Lepidoptera Of Fowler Woods State Nature Preserve, Richland County, Ohio., Roy W. Rings, Eric H. Metzler

The Great Lakes Entomologist

A survey of the Lepidoptera occurring at Fowler Woods State Nature Preserve in Richland County, Ohio was conducted from 1986 to 1988. Sampling was done by ultraviolet light traps, mercury vapor light and ultraviolet light and collecting sheet, bait traps, sugaring and netting. A total of 419 species and forms was identified and tabulated. It was estimated that the actual number of species at this site is 655. Representative specimens have been deposited in the Insect Reference Collection at the Ohio Agricultural Research and Development Center, The Ohio State Univer- sity, Wooster, Ohio.


The Occurrence Of Ditylus Caeruleus In Michigan (Coleoptera: Oedemeridae), With Observations On Its Range, Daniel K. Young 2017 University of Wisconsin

The Occurrence Of Ditylus Caeruleus In Michigan (Coleoptera: Oedemeridae), With Observations On Its Range, Daniel K. Young

The Great Lakes Entomologist

The oedemerid beetle, Ditylus caeruleus, is recorded for the first time from Mar- quette County, Michigan. Bionomical data associated with the specimens represent the first such information for this species. Eight additional new Michigan county records for the species are also reported, including the first specimens from the Lower Peninsula. The distributional range of caeruleus is highly correlated with the Great Lakes, the 81. Lawrence River, and coastal Maine. Implications of this distribution pattern relating to possible development of larvae in driftwood and the potential significance of rafting as a dispersal mechanism are also discussed.

The Great Lakes Entomologist

(excerpt)

Every once in a while a reference book comes along that is a special pleasure to review. Such a tome is The Plant-Feeding Gall Midges of North America by Raymond J. Gagne. You can appreciate the scope of this book only by realizing that gall midges attack numerous families of gymnosperms and angiosperms; both monocots and dicots. Greatly needed by entomologists and botanists, Gagne's book not only updates Felt's and Barne's classic works of the forties and fifties, but it also supersedes them!


Spatial Distribution Of The Goldenrod Ball Gall Insects, John L. Confer 2017 Ithaca College

Spatial Distribution Of The Goldenrod Ball Gall Insects, John L. Confer

The Great Lakes Entomologist

The goldenrod ball gall fly, Eurosta solidaginis (Diptera: Tephritidae), is parasitized by two eurytomid wasps and preyed on by a mordellid beetle, and two bird species. The birds are known to prey most intensively near a forest edge. The proportion of fly larva parasitized and preyed on by insects was examined, and a decline in the proportional abundance of beetle larvae near the forest was noted. The possible role of birds as the selective force for this distribution is considered.


Residual Action Of Slow Release Systemic Insecticides On Rhopalosiphum Padi (Homoptera: Aphididae) On Wheat, J. E. Araya, J. E. Foster, M. M. Schreiber, R. E. Wing 2017 University de Chile

Residual Action Of Slow Release Systemic Insecticides On Rhopalosiphum Padi (Homoptera: Aphididae) On Wheat, J. E. Araya, J. E. Foster, M. M. Schreiber, R. E. Wing

The Great Lakes Entomologist

Slow release formulations of acephate and carbofuran encapsulated in pearl corn­ starch or corn flour granules were applied to the soil at seeding time of potted 'Caldwell' wheat in the laboratory. Dosages of these insecticides were adjusted to a standard of IO kg/ha of a 10"10 granular formulation of carbofuran. The residual action of these insecticide treatments against Rhopalosiphum padi were compared with those obtained with that of carbofuran 150 at corresponding dosages and foliar sprays of solutions of acephate (25"10 EC) at 0.2"10 and carbofuran (4F) at 1.25"10, applied 12 d after ...


Marking Adult Colorado Potato Beetles, Leptinotarsa Decemlineata (Coleoptera: Chrysomelidae) Using Paper Labels, Michael A. Caprio, Deborah Miller, Edward Grafius 2017 Michigan State University

Marking Adult Colorado Potato Beetles, Leptinotarsa Decemlineata (Coleoptera: Chrysomelidae) Using Paper Labels, Michael A. Caprio, Deborah Miller, Edward Grafius

The Great Lakes Entomologist

The smooth elytra of adult Colorado potato beetle, Leptinotarsa decemlineata, make this insect difficult to make efficiently for long-term field studies. Enamel paint marks fell off rapidly, and after 28 days, 25010 of marked beetles had lost all four original marks. Use of small paper labels glued to the elytra after an acetone wash and sanding pretreatment was the most effective method for long term marking of individual beetles. Mortality in labeled laboratory-reared and field-collected beetles did not increase when compared to unmarked beetles.


Late Winter Foraging By Honeybees (Hymenoptera: Apidae) At Sapsucker Drill Holes, Charles E. Williams 2017 Washington and Lee University

Late Winter Foraging By Honeybees (Hymenoptera: Apidae) At Sapsucker Drill Holes, Charles E. Williams

The Great Lakes Entomologist

Observations of Apis mellifera foraging at sapsucker drill holes were made during February 1988 in southwestern Virginia. Foraging bouts were dependent upon temperature; more bees visited drill holes when ambient temperatures exceeded 10oC. Honeybees did not feed directly at drill holes but collected congealed sap from bark surfaces.


Survival And Longevity Of Otiorhynchus Ligustici (Coleoptera: Curculionidae) In Alfalfa Hay Bales In Eastern Ontario, D. G. Harcourt, K Bereza 2017 Agriculture Canada

Survival And Longevity Of Otiorhynchus Ligustici (Coleoptera: Curculionidae) In Alfalfa Hay Bales In Eastern Ontario, D. G. Harcourt, K Bereza

The Great Lakes Entomologist

The alfalfa snout beetle, Otiorhynchus ligustici, a pest of European origin, has recently spread into mainland Ontario. A two-year study showed that dispersing adults incorporated into bales of alfalfa during harvest can survive therein for up to 46 days of storage in a mow. Furthermore, they can remain fertile for most of this period. This has important implications with respect to the shipment of hay from infested areas.


Mass Rearing The Gypsy Moth Pupal Parasitoids Brachymeria Lasus And Brachymeria Intermedia (Hymenoptera: Chalcididae) For Small-Scale Laboratory Studies, S. D. Stowell, H. C. Coppel 2017 University of Wisconsin

Mass Rearing The Gypsy Moth Pupal Parasitoids Brachymeria Lasus And Brachymeria Intermedia (Hymenoptera: Chalcididae) For Small-Scale Laboratory Studies, S. D. Stowell, H. C. Coppel

The Great Lakes Entomologist

An economical technique was developed for mass rearing the gypsy moth para- sitoids Brachymeria lasus and B. intermedia using a factitious host, the greater wax moth, Galleria mellonella (Lepidoptera: pyralidae). Percentages of host pupae producing adult B. lusus and B. intermedia were 72.2 and 67.5, respectively. Percentages of adult wax moths emerging from groups of pupae exposed to populations of B. lasus and B. intermedia were 3.4 and 9.8, respectively. Mean emergence times of males and females from parasitized pupae incubated at 29° C. were 12.1 days and 13.8 days for B. lasus and ...


Distribution Of Pelecinus Polyturator In Wisconsin (Hymenoptera: Pelecinidae), With Speculations Regarding Geographical Parthenogenesis, Daniel K. Young 2017 University of Wisconsin

Distribution Of Pelecinus Polyturator In Wisconsin (Hymenoptera: Pelecinidae), With Speculations Regarding Geographical Parthenogenesis, Daniel K. Young

The Great Lakes Entomologist

The geographical distribution of Pelecinus polyturator in Wisconsin is summarized. Only five males have been recorded; a recently collected male from the University of Wisconsin Field Station in Ozaukee County represents the first male collected in the state in over 40 years. Speculations on the possible significance and implications of geographical parthenogenesis relative to Pelecinus are offered.

A History Of The Eastern Larch Beetle, Dendroctonus Simplex (Coleoptera: Scolytidae), In North America, D. W. Langor, A. G. Raske 2017 University of Alberta

A History Of The Eastern Larch Beetle, Dendroctonus Simplex (Coleoptera: Scolytidae), In North America, D. W. Langor, A. G. Raske

The Great Lakes Entomologist

The eastern larch beetle, Dendroctonus simplex, is reputedly a secondary pest but may attack and kill tamarack and ornamental larches throughout Canada, the northeastern United Stales, and Alaska. Isolated infestations of this pest have been reported for over 100 years. The first recorded widespread outbreaks of D. simplex started in eastern Canada and the northeastern United States as well as in Alaska in the mid-1970s. During the outbreak in the Atlantic provinces, in excess of 1.4 million m3 of tamarack was killed. No damage estimates are available for Quebec and the United States. Insect defoliators were the most common ...


Effect Of Selecting Cereal Leaf Beetle (Coleoptera: Chrysomelidae) Males By Age And Feeding Behavior On Nondiapause Progeny, S. G. Wellso, R. P. Hoxie 2017 Purdue University

Effect Of Selecting Cereal Leaf Beetle (Coleoptera: Chrysomelidae) Males By Age And Feeding Behavior On Nondiapause Progeny, S. G. Wellso, R. P. Hoxie

The Great Lakes Entomologist

In a nondiapause culture of cereal leaf beetles, Oulema melanopus (Coleoptera: Chrysomelidae), females ovipositing within 20 days after emergence were considered nondiapause. However, sexually active males in the same generation could be nondiapause or prediapause. Changes in the nondiapause incidence were compared between progenies from> 15 day old males that were feeding actively and photopositive (considered 'nondiapause' males) and progenies from younger males (nonselected males). Nondiapause females increased by 19% (n = 35 generations) and decreased 22% (n 31 generations) in the progenies of 'nondiapause' and nonselected males, respectively, suggesting that nondiapause males were selected in the former group, but prediapause ...


The Insects Of Treeholes Of Northern Indiana With Special Reference To Megaselia Scalaris (Diptera: Phoridae) And Spilomyia Longicornis (Diptera: Syrphidae), Robert S. Copeland 2017 University of Notre Dame

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.


Sampling Technique For Larvae Of The Alfalfa Snout Beetle, Otiorhynchus Ligustici (Coleoptera: Curculionidae), D. G. Harcourt, M. R. Binns 2017 Agriculture Canada

Sampling Technique For Larvae Of The Alfalfa Snout Beetle, Otiorhynchus Ligustici (Coleoptera: Curculionidae), D. G. Harcourt, M. R. Binns

The Great Lakes Entomologist

This paper presents a sampling procedure for estimating larval populations of the alfalfa snout beetle, Otiorhynchus ligustici. The method is based on counts of the larvae taken in 16 x 16 cm quadrats of soil during early fall when the grubs are in their final two instars and feeding just below the crowns of the plant. Analysis of sampling variability showed that 200 quadrats per field are necessary to obtain adequate precision for intensive population studies but that 50 quadrats are sufficient for survey work. The pattern of counts was overdispersed but conformed to the negative binomial distribution.

Ground Beetles From A Remnant Oak-Maple-Beech Forest And Its Surroundings In Northeastern Ohio (Coleoptera: Carabidae), Foster F. Purrington, John E. Bater, Maurizio G. Paoletti, Benjamin R. Stinner 2017 Ohio Agricultural Research and Development Center

Ground Beetles From A Remnant Oak-Maple-Beech Forest And Its Surroundings In Northeastern Ohio (Coleoptera: Carabidae), Foster F. Purrington, John E. Bater, Maurizio G. Paoletti, Benjamin R. Stinner

The Great Lakes Entomologist

We report 66 ground beetle species in 14 tribes from a natural preserve in northeastern Ohio (Stark County). Six species are new state records. Data from pitfall trap transects across adjoining habitats suggest narrow habitat preferences in some species and broad tolerances in others.

Trends toward flightlessness in forest species and macroptery in the fauna of disturbed agricultural sites are apparent.
