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. …

Adult Trichoptera Of The Devil Track River Watershed, Cook County, Minnesota And Their Role In Biomonitoring., David B. Maclean

The Great Lakes Entomologist

Thirty two light trap collections of 7,797 adult Trichoptera made from 1990-1992, show that the Devil Track River Watershed in northeast Minnesota includes at least 16 families, 41 genera, and 101 species of caddisflies including three new state records: Agyrpnia colorata, Agrypnia obsoleta, and Polycentropus glacialis. The greatest number of species were represented by the families Limnephilidae (21), Leptoceridae (19), Hydroptilidae (13), Polycentropodidae (12), nidae (10), and Hydropsychidae (9). Twenty two species were collected sites and 46 at one or two sites. The greatest number of species (81) was collected from the Devil Track River and Devil Track …

Rapd Pcr Confirms Absence Of Genetic Variation Between Insecticide Resistant Variants Of The Green Peach Aphid, Myzus Persicae (Homoptera: Aphididae), A. Al-Aboodi, R. H. Ffrench-Constant

The Great Lakes Entomologist

Previous allozyme analysis has revealed an apparent absence of enzyme variability in the green peach aphid, Myzus persicae (Sulzer). We are interested in determining the genetic relatedness of individual M persicae clones carrying different numbers of esterase 4 (E4) gene copies conferring resistance to insecticides, in order to determine how many times and in what geographic locations resistance via gene duplication may have evolved. We have therefore extended the analysis of genetic variability in M. persicae to the DNA level using random amplification of polymorphic DNA (RAPD) with single 10 mer oligonucleotide primers. Here we report a lack of variability …

Aquatic Hydrophilidae And Hydraenidae Of Wisconsin (Coleoptera). Ii. Distribution, Habitat, Life Cycle And Identification Of Species Of Hydrobiini And Hydrophilini (Hydrophiudae: Hydrophilinae), William L. Hilsenhoff

The Great Lakes Entomologist

Nine genera and 30 species of Hydrobiini and 3 genera and 12 species of Hydrophilini were found in Wisconsin, including a new species of Laccobius. Life cycles of all species of lentic Hydrobiini were similar; adults overwinter in terrestrial habitats, return to aquatic sites in spring to mate, oviposit adjacent to these sites, and eventually die. The riparian larvae complete development, pupate, and emerge sometime during the summer depending on the species and habitat, and teneral adults disperse to suitable aquatic habitats. Adults enter overwintering sites in late summer or early autumn. Lotic species of Cymbiodyta have a similar …

(excerpt)

It is rare that a publication this complete and well-illustrated is issued on the fauna of a state, and even rarer still, that such a publication is made possible by a collaborative effort of many individuals and several agencies. The Butterflies and Skippers of Ohio is a volume made possible by the efforts of the Ohio Lepidopterists and the Ohio Biological Survey. The Ohio Lepidopterists are for the most part, a number of serious amateurs and professional entomologists that have long desired to provide a check-list of the Ohio Butterfly fauna.

New Larval Host Plant And Behavior Of Chlosyne Gorgone (Lepidoptera: Nymphalidae), Andrew H. Williams

The Great Lakes Entomologist

(excerpt)

On 31 July 1994, at 1600 hr, an aggregation of eight larvae of Chlosyne gorgone (Hubner) was found at Bush Clover Prairie, in Grant Co., Wisconsin. The larvae were feeding on the upper surface of a leaf of Echinacea pallida (Asteraceae), eating away the top tissue and leaving the translucent lower epidermis in place in an area about 1 cm wide and 4 cm long, oriented length- wise along the lanceolate leaf.

Dendroctonus Valens And Hylastes Porculus (Coleoptera: Scolytidae): Vectors Of Pathogenic Fungi (Ophiostomatales) Associated With Red Pine Decline Disease., Kier D. Klepzig, Eugene B. Smalley, Kenneth F. Raffa

The Great Lakes Entomologist

A study was conducted to determine whether Dendroctonus valens and Hylastes porculus could vector their commonly associated fungi to red pine. Field collected adult D. valens transmitted Leptographium terebrantis, Leptographium procerum and Ophiostoma ips into 45%, 30%, and 5%, respectively of the wounded red pine roots onto which they were caged. Field collected H. porculus transmitted L. terebrantis, L. procerum and O. ips into 55%, 40%, and 5%, respectively, of the wounded red pine roots onto which beetles were caged. None of the control roots, which were mechanically wounded only, were found to contain O. ips, whereas only …

Abundance And Flight Activity Of Some Histeridae, Hydrophilidae And Scarabaeidae (Coleoptera) In Southern Quebec, Canada, Claire Levesque, Gilles-Yvon Levesque

The Great Lakes Entomologist

We collected adult beetles with four unbaited flight intercept traps in southern Quebec, from early May through late October, in 1987, 1988 and 1989. We captured a total of 146 Histeridae (9 species), 668 Hydrophilidae (29 species) and 428 Scarabaeidae (25 species), including 25 Holarctic or introduced species in North America, mainly non-forest hydrophilids and scarabs.The Sphaeridiinae and Aphodiinae represented, respectively, 78% of hydrophilid catches and 86% of scarab captures. We suggest that adults of Aphodius prodromus, the most common scarab species, are generalist detritivores. Overwintered adults of this species, mainly females, flew in spring, and new generation adults …

Ground Beetles Of Islands In The Western Basin Of Lake Erie And The Adjacent Mainland (Coleoptera: Carabidae, Including Cicindelini), K. W. Will, F F. Purrington, D. J. Horn

The Great Lakes Entomologist

We report 241 species representing 63 genera of ground beetles from the islands of the western basin of Lake Erie and selected mainland sites from a 1991-93 survey, plus specimens examined in public and private collections, and previously published sources. Most species are generally distributed; however, a restricted population of Sphaeroderus schaumii schaumii we rediscovered is no doubt imperiled. Comparison of wing morphotype frequencies of the Lake Erie island species with mainland populations from studies in Ohio and Michigan support a hypothesis that vagility is of increased import in the islands. Regression and correlation analysis show a positive relationship between …

Aquatic Hydrophilidae And Hydraenidae Of Wisconsin (Coleoptera). I. Introduction, Key To Genera Of Adults, And Distribution, Habitat, Life Cycle, And Identification Of Species Of Helophorus Fabricius, Hydrochus Leach, And Berosus Leach (Hydrophilidae), And Hydraenidae, William L. Hilsenhoff

The Great Lakes Entomologist

The 3,920 Helophorus (Helophorinae) adults collected in Wisconsin included 16 species, two of which were new species. Helophorus orientalis and H. lacustris predominated. Three types of univoltine life cycles occurred: (1) adults overwinter in terrestrial habitats and larvae complete development in riparian habitats from early summer to early autumn, depending on the spe­cies; (2) the same as type 1, except eggs and a few adults overwinter; (3) larvae, pupae, and/or recently emerged adults overwinter and teneral adults occur in aquatic habitats in early spring. Nine species of Hydrochus (Hydrochinae) were found among 6,278 adults, with H. squamifer predominating. All had …

Tillering Response Of 'Monon' And 'Newton' Winter Wheats Infested With Biotype L Hessian Fly (Diptera: Cecidomyiidae) Larvae, Stanley G. Wellso, Robert P. Hoxie

The Great Lakes Entomologist

Two wheat, Triticum aestivum, cultivars that differed in their ability to tiller were infested by ovipositing Hessian flies, Mayetiola destructor, under similar controlled conditions. Since a larva typically stunts and kills the stem where it feeds and develops, tiller development of fly infested-wheat seedlings is an important plant trait relative to grain yield. 'Monon' tillered more than 'Newton at the 0 infestation level (control). 'Monon' had about the same number of tillers at 0, 1, 2, and 3 puparia (indicative of the number of feeding larvae) per plant; and 'Newton' had fewer tillers at 0 than 1, 2, or …

A Bait Attractant Study Of The Nitidulidae (Coleoptera) At Shawnee State Forest In Southern Ohio, R. N. Williams, M. S. Ellis, G. Keeney

The Great Lakes Entomologist

Four baits were tested for efficacy in attracting sap beetles (Nitidulidae) at two sites in the Shawnee State Forest over two collection periods in 1992. Species taken were categorized into three groups: abundant, moderate, and uncommon. At Site 1, nitidulids displayed a strong preference for whole wheat bread dough, followed by fermenting brown sugar, and fermenting malt/molasses solution, and vinegar, respectively. Site 2 collections showed a similar trend to Site 1, but the order of preference was switched for brown sugar and malt/molasses solution. Of the 20 species collected, six species were abundant, seven species were moderate, and seven species …
