Occurrence Of Libellulid Dragonflies (Odonata: Libellulidae) In Southeastern Michigan And Adjacent Essex County, Ontario, Michael A. Kielb

The Great Lakes Entomologist

During 1994-1995 extensive field work was conducted in southeastern Michigan in an attempt to assess the species population and composition of libellulid dragonflies. Additional field work was conducted on dragonflies from southwestern Ontario migrating into southeastern Michigan. Comparisons were made with the species listed for this area 37 years earlier in Kormondy (1958) anticipating changes due to wetland reductions and the effects of pesticides. With one exception, all species listed in Kormondy were observed. Ad- ditionally, one species, unknown from this area as of 1958, was encountered.

Maxwell H. Gluck Equine Research Center Faculty Publications

Background: The recent emergence of Zika virus (ZIKV) in Brazil and its precipitous expansion throughout the Americas has highlighted the urgent need for a rapid and reliable on-site diagnostic assay suitable for viral detection. Such point-of-need (PON), low-cost diagnostics are essential for ZIKV control in vulnerable areas with limited resources.

Methods: We developed and evaluated a ZIKV-specific field-deployable RT-iiPCR reagent set targeting the E gene for rapid detection of ZIKV in ZIKV-spiked human and mosquito specimens, and compared its performance to the Center for Disease Control and Prevention (CDC) and Pan American Health Organization (PAHO) RT-qPCR assays targeting the E …

Urophora Quadrifasciata (Diptera: Tephritidae), An Introduced Seedhead Fly New To Midwestern North America, A. G. Wheeler Jr.

The Great Lakes Entomologist

The Old World tephritid Urophora quadrifasciata, a gall-inducing seed- head fly, was released in western and eastern North America for the biological control of knapweeds, Centaurea spp. (Asteraceae). Its establishment in the West (BC, CA, ID, MT, OR, WA) and in the East (CT, MA, MD, NH, NJ, NY, PA, RI, VA, VT, WV) has been previously reported. Collections from eastern Minnesota and western Michigan in 1995 are the first for the Northcentral region of North America.

A Michigan Record For Clytus Marginicollis (Coleoptera: Cerambycidae: Clytini), James E. Zablotny

The Great Lakes Entomologist

Clytus marginicollis Castlenau and Gory is a small, rarely collected clytine cerambycid endemic to coniferous forests of Eastern North America (Knull 1943, Linsley 1964). Gosling (1973) did not mention any records for it in his survey of Michigan cerambycids. Knull (1943) reports that this species probably occurs in Ohio but he had seen no specimens to confirm its presence.

Adult Female Mydas Clavatus (Diptera: Mydidae) Feeding On Flowers In Wisconsin, Andrew H. Williams

The Great Lakes Entomologist

An adult female of Mydas clavatus was observed feeding on flowers. This confirms that females of this species feed as adults and that they feed on flowers. This species is reported for the first time from Wisconsin and Minnesota.

It has previously been recorded \ from Wisconsin. Cahn (1915) reported it from the Wingra Springs region in \ central Dane County, and Keeton (1960) reported it from Clark and Sauk Counties.

Economics Of Cell Partitions And Closures Produced By Passaloecus Cuspidatus (Hymenoptera: Sphecidae), John M. Fricke

The Great Lakes Entomologist

Sphecid wasps, Passaloecus cuspidatus were observed gathering fresh pine resin (Pinus strobus) which they used for creating partitions and closures in their nests. Based upon measurements taken of the cells, and an estimate of the load carried by the wasps, the number of collecting trips made by the wasps was correlated with the quantity of resin contained within the nest partitions and closures.

A Note On The Sympatric Collection Of Chymomyza (Diptera: Drosophilidae) In Virginia's Allegheny Mountains, Henretta Trent Band

The Great Lakes Entomologist

The attraction of two Chymomyza species, C. procnemoides and C. aldrichii, to the same damaged tree over 19 days in summer 1987 near Mt. Lake Hotel, Giles Co., Virginia is documented, confirming a previous report that Chymomyza species may be sympatric on the same fresh damaged tree/cut wood. A total of 17 males and 7 females were captured. An excess of males to females captured has been reported in Japan and Hungary.

Slaterobius Insignis (Heteroptera: Lygaeidae): Association With Granite Ledges And Outcrops In Minnesota, A. G. Wheeler Jr.

The Great Lakes Entomologist

Adults and late-instar nymphs of the wide-ranging myrmecomorphic lygaeid Slaterobius insignis were collected in northern Minnesota from cracks of granite outcrops and ledges, a habitat differing somewhat from that reported elsewhere. At two of the four sites, S. insignis was observed in plant-and litter-filled cracks with nymphs of the lygaeid Trapezonotus arenarius. All adults of the polymorphic S. insignis observed on granite were brachypters that belonged to the dark color morph of the species. Individuals occurred on rock surfaces with a black ant, Formica subsericea, which they resembled in appearance and behavior.

An Allometric Study Of The Boxelder Bug, Boisea Trivittata (Heteroptera: Rhopalidae), Scott M. Bouldrey, Karin A. Grimnes

The Great Lakes Entomologist

An allometric study was conducted on the boxelder bug, Boisea trivittata, to confirm the number ofinstars and to identify characteristics most useful for rapid instar identification of field samples. Analysis of field populations collected throughout the 1990-92 seasons indicated that there were five instars, clearly defined on the basis of size and the presence of wing pads. This finding is in contrast with the only other published study on stages of the boxelder bug, which claims there are six nymphal instars.

Size data gathered from field populations were substantiated by laboratory growth studies. Head width and/or second antennal segment …

Parasitism Of Plathypena Scabra (Lepidoptera: Noctuidae) By Sinophorus Teratis (Hymenoptera: Ichneumonidae), Daniel M. Pavuk, Charles E. Williams, Douglas H. Taylor

The Great Lakes Entomologist

(excerpt)

A study was conducted at the Ecology Research Center, Miami University, Butler County, Ohio, during the summer of 1990 to examine the effects of strip intercropping sorghum and soybean on the occurrence of parasitoids and incidence of disease in larvae ofthe green cloverworm, Plathypena scabra (F.) (Lepidoptera: Noctuidae), a sporadic pest of soybeans. The details of the experimental design and results are reported elsewhere (Williams et al. 1995).

Temperature Effects On Development Of Three Cereal Aphid Parasitoids (Hymenoptera: Aphidiidae), N. C. Elliot, J. D. Burd, S. D. Kindler, J. H. Lee

The Great Lakes Entomologist

Temperature is an important climatological variable that influences the biology and ecology of insects. Poor climatic adaptation can limit the effectiveness of parasitic insects in biological control. Two exotic parasites (Syrian Diaeretiella rapae (M'Intosh) and Argentinean Aphidius colemani Viereck) imported for biological control of the Russian wheat aphid, Diuraphis noxia (Mordvilko), and one native parasite (Diaeretiella rapae) were reared in growth chambers in three fluctuating temperature regimes with average daily temperatures of 12, 18, and 24°C. Estimates of temperature thresholds for immature development were 3.3, 3.5, and 2.8°C, for Oklahoman D. rapae, Syrian D. rapae, and …

The Gonotrophic-Age Structure Of A Population Of The Simulium Venustum Complex (Diptera: Simuliidae) In Algonquin Park, Ontario, Stephen M. Smith, Alan Hayton

The Great Lakes Entomologist

Eight techniques for the determination of parity and gonotrophic age were assessed for the obligatorily anautogenous blackfly-species complex, Simulium venustum Say. All females could be age-graded by the presence or absence of dilatations on the ovarioles. However, multiple dilatations on a single ovariole were not found and the Polovodova method could not be used to determine the number of completed gonotrophic cycles. Most females could be age-graded by the appearance of the Malpighian tubules, which undergo morphological changes, probably as a result of a bloodmeal. In some cases, the size of the fat body, the presence of retained (relict), mature …

Survey Of Predators Associated With European Red Mite (Panonychus Ulmi; Acari: Tetranychidae) In Ohio Apple Orchards, Celeste Welty

The Great Lakes Entomologist

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 …

Observations Of Spring Larvae Of Lycaeides Melissa Samuelis (Lepidoptera: Lycaenidae) In Central Wisconsin, Ann B. Swengel

The Great Lakes Entomologist

At 36 sampling sites in central Wisconsin 1991-94, 358 spring larvae of the Karner blue (Lycaeides melissa samuelis) ranged from 1.9-17.0 mm in length, with only two >15.0 mm. The number of attending ants (mean 2.0, range 0-25) covaried strongly with larval size, with ants attending all larval instars. Height of wild lupine (Lupinus perennis), this butterfly's only larval food plant, correlated significantly with larval length, and larvae did not appear to hatch too soon in cool springs to have adequate forage. Larval presence and size correlated significantly with five of seven types of feeding signs on the lupines. …
