Parasitoids Of Chionaspis Pinifoliae (Homoptera: Diaspididae) In Iowa, Daniel J. Burden, Elwood R. Hart

The Great Lakes Entomologist

Three parasitoids (Hymenoptera: Encyrtidae: Aphelininae), Aphytis diaspidis, Coccobius varicornis, and Marietta pulchella, were recovered from field collections of the pine needle scale, Chionaspis pinifoliae, on Pinus sylvestris in central Iowa. Parasitoid mean time (± SEM) to emergence from overwintered scale mummies occurred at 46.6 (4.6) and 23.9 (1.3) days for C. varicornis and M. pulchella, respectively, using a 16L:8D photoperiod and a corresponding temperature regime of 22°C and 18°C. Growing-season parasitism level on field-collected female C. pinifoliae was 15%; parasitoid community composition was 86% A. diaspidis, 12% C. varicornis, and 2% M. pulchella.

Gyrinidae Of Wisconsin, With A Key To Adults Of Both Sexes And Notes On Distribution And Habitat, William L. Hilsenhoff

The Great Lakes Entomologist

More than 25,000 adult gyrinids that include 24 species were studied from all areas of Wisconsin. Dineutus discolor, Gyrinus aeneolus, G. analis, G. bifarius, and G. marginellus are lotic; D. assimilis, G. aquiris, G. confinis, and G. dichrous apparently breed in both lotie and lentic habitats; and the remaining species probably breed primarily in deep ponds or littoral areas of lakes and impoundments. Most collections were from streams in late summer and autumn because adults of almost all lentic species fly to streams to overwinter and these overwintering aggregations were easily collected. A key to adults of Wisconsin species …

Aggregation Behavior Of A Willow Flea Beetle, Altica Subplicata (Coleoptera: Chrysomelidae), Catherine E. Bach, Deborah S. Carr

The Great Lakes Entomologist

This study examined the aggregation behavior of a specialist insect herbivore, Altica subplicata (Coleoptera: Chrysomelidae), on its host plant, Salix cordata. Mark-recapture experiments were conducted in patches of S. cordata growing along the shores of Lake Huron. Beetles aggregated on individual host plants, but did not aggregate in larger areas containing many host plants. Plants colonized by marked beetles had significantly higher abundances of unmarked beetles than did plants that were not colonized by marked beetles.

Experimental manipulations of the number of beetles present on plants showed that colonization rates by marked beetles were higher on plants with conspecifics …

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 validity.

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

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 Plant-Feeding Gall Midges Of North America. Raymond J. Gagne. Cornell University Press, Ithaca, Ny 14850. 1989. 356 Pp. $45.00 (Cloth)., Louis F. Wilson

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

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

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 seedling emergence. The residual action of carbofuran …

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.

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.

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

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 11.9 days and 13.5 days for …

Speculations on the possible significance and implications of geographical parthenogenesis relative to Pelecinus are offered.

Economic Impact Of The Sugarcane Aphid Outbreak In South Texas, Samuel D. Zapata, Rebekka Dudensing, Danielle Sekula, Gabriela Esparza-Díaz, Raul Villanueva

Entomology Faculty Publications

The objective of this study was to estimate the economic impact of the sugarcane aphid (SCA) outbreak in the Rio Grande Valley (RGV), Texas. Local producers were surveyed to gather detailed information about crop production and pest control practices. Collected data were used to estimate the reduction in profit associated with the SCA infestation, as well as the monetary value of the prevented loss attributed to control efforts. Sorghum industry losses were then used to assess the overall economic impact of the SCA outbreak in the RGV economy.

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

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 …

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

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.

Naiadacarus mydophilus, new species, is described from deutonymphs phoretic on Brachypalpus oarus from Michigan. Based upon known biologies of host insects and other mite species which utilize these hosts, it is hypothesized that N. lashingi and N. mydophilus may inhabit wet decaying wood andior …

Ecology, Mating And Nesting Of Tachypompilus Ferrugineus Nigrescens (Hymenoptera: Pompilidae), Frank E. Kurczewski

The Great Lakes Entomologist

An aggregation of Tachypompilus Jerrugineus nigrescens was studied during mid­ summer 1988 in Syracuse, NY. Wasp activity was focused on a 2 m high cemetery monument near a gravelly roadway. Males perched on thc stone, chased one another and pursued incoming females in flight. Details of mating are described. Both sexes spent the night and periods of inclement weather inside a narrow crevice near the base of the monument. Females flew around the monument, landed frequently and made exploratory walks inside of the crevice. They were observed searching for prey and transporting paralyzed spiders backward on the ground. Seven conical …
