Effects Of Enamel Paint On The Behavior And Survival Of The Periodical Cicada, Magicicada Septendecim (Homoptera) And The Lesser Migratory Grasshopper, Melanoplus Sanguinipes (Orthoptera)., J. R. Cooley, G. S. Hammond, D. C. Marshall

The Great Lakes Entomologist

We present information compiled from several studies on the effects of methods for marking individual arthropods on their longevity and behavior. Results from our own research on effects of enamel paint marking on two in- sect species, the periodical cicada, Magicicada septendecim, and the lesser migratory grasshopper, Melanoplus sanguinipes, are also presented. Neither species showed any adverse survivorship or behavioral effects from marking.

Evidence Of Long Range Transport Of A Dark Morph Swal­Lowtail Butterfly (Papilio Glaucus) On A Storm Front Into Northern Michigan (Lepidoptera: Papilionidae), J. Mark Scriber, Mark D. Deering, Aram D. Stump

The Great Lakes Entomologist

A dark morph female Papilio glaucus was captured in the middle of a P. canadensis population in the center of Dickinson County, in Michigan's Upper Peninsula. We are unaware of any dark female ever being captured at this latitude, and none within 400 km has ever before been reported. Morphological wing traits all score this dark female as P. glaucus, with all 31 of the other (yellow) females captured from the same group of nectar sources scoring as P. canadensis. Two diagnostic electrophoretic allozymes (PGD and LDH) show all 24 males to have 100% P. canadensis alleles, and …

Eutarsopolipus fischeri n.sp. (Acari: Podapolipidae) is described from the carabid beetle, Harpalus pennsylvanicus (DeGeer) and compared with the other species in the pterostichi group of Eutarsopolipus. Keys to groups of Eutarsopolipus and to species in the pterostichi group are provided.

New Record For The Endangered Crawling Water Beetle, Brychius Hungerfordi (Coleoptera: Haliplidae) In Michigan Including Water Chemistry Data, Troy A. Keller, Michael Grant, Bert Ebbers, Robert Vande Kopple

The Great Lakes Entomologist

We report the discovery of the Federally endangered crawling water beetle, Brychius hungerfordi Spangler, in a new watershed in the northern lower peninsula of MIchigan. The site was found on the Carp River, a lake draining first-order stream. Nine water chemistry parameters were measured from three known locations of B. hungerfordi and from three sites where no B. hungerfordi have been found. Water from sites with known populations of adult beetles showed low soluble reactive phosphorus, but were similar to other similar rivers in northern Michigan.

Development, Survival And Phenology Of The Sweetclover Weevil Parasitoid, Pygostolus Falcatus (Hymenoptera: Braconidae), Lindsey R. Milbrath, Michael J. Weiss

The Great Lakes Entomologist

Biennial sweetclovers were widely used for soil improvement and as for- ages in the first half of the 1900s. The introduction of the sweetclover weevil, Sitona cylindricollis, caused a drastic decline in sweetclover acreage. In North Dakota, yellow sweetclover, Melilotus officinalis, is still the legume of choice on organic farms. In an effort to control the weevil, the thelyotokous parasitoid Pygostolus falcatus was imported. Parasitoids were studied for temperature-dependent development, and adult longevity as influenced by temperature and availability of provisions. Development from egg to adult at 15, 20, 25 and 30°C was 58, 28, 22 and 21 …

Rhizedra lutosa is a Eurasian species that is rapidly establishing populations across the United States. Argyrotaenia cockerellana is primarily known from the western United States, with eastern records from Nebraska and Ontario, Canada.

The Inheritance Of Diagnostic Larval Traits For Interspecific Hybrids Of Papilio Canadensis And P. Glaucus (Lepidoptera: Papilionidae), J. Mark Scriber

The Great Lakes Entomologist

Traits distinguishing the closely related tiger swallowtail butterfly species, Papilio canadensis and P. glaucus, include fixed differences in diagnostic sex-linked and autosomal allozymes as well as sex-linked diapause regulation, and sex-linked differences in oviposition behavior. Larval detoxification abilities for plants of the Salicaceae and Magnoliaceae families are dramatically different and basically diagnostic as well. The distinguishing morphological traits of the adults and larvae have not been genetically characterized. Here we describe the segregation of diagnostic larval banding traits in offspring from the 2 species in their hybrid and reciprocal backcross combinations. Elucidation of genetic basis, and linkage relationships of …

New Wisconsin Records For A Hemileuca (Lepidoptera: Saturniidae) Using Menyanthes Trifoliata (Solanales: Menyanthaceae) And Betula Pumila (Betulaceae), James J. Kruse

The Great Lakes Entomologist

A population of Hemileuca maia species complex was observed feeding on Menyanthes trifoliata and Betula pumila. This confirms the presence of a second population of these moths using M. trifoliata in Wisconsin, and is only the fourth known locality for such populations. This is the first report of Hemileuca feeding on B. pumila in Wisconsin. The Hemileuca populations of the Great Lakes region are discussed, and the first map of the distribution of Hemileuca in Wisconsin is provided.

Insects Associated With Butternut And Butternut Canker In Minnesota And Wisconsin, Steven A. Katovich, Michael E. Ostry

The Great Lakes Entomologist

Butternut, Juglans cinerea, is being killed throughout its native range in North America by the fungus Sirococcus clavigignenti-juglandacearum. In addition to rain splashed spores, it is thought that the fungus may have spread over long distances to infect widely scattered butternut by insect vectors During surveys in 1995 and 1996 we found several insect species in close association with diseased butternut trees, and spores of S. clavigignenti-juglandacearum were isolated in pure culture from the bodies of some of these insects. Potential insect vectors were species in the coleopteran genera Eubulus (Curculionidae), Laemophlaeus (Laemophloeidae), and Glischrochilus (Nitidulidae). Because several …

Burying Beetles (Coleoptera: Silphidae) Of The Apostle Islands, Wisconsin: Species Diversity, Population Density And Body Size, Stephen T. Trumbo, Shelly Thomas

The Great Lakes Entomologist

Over 2400 burying beetles, representing six species (Nicrophorus defodiens, N. sayi, N orbicollis, N. tomentosus, N vespilloides, and N. pustulatus), were trapped from 27 June to 4 August, 1996 at nine study sites (3 small islands, 3 large islands, and 3 mainland locations) centered around the Apostle Islands National Lakeshore in northern Wisconsin. Species diversity was greatest on the mainland and least on the smallest islands « 600 ha). Nicrophorus defodiens, the smallest of the six species, was marginally overrepresented on the smallest islands. We hypothesize that this occurred because N. defodiens can maintain a larger …

Observations Of First Occurrence And Severity Of Potato Leafhopper, Empoasca Fabae (Harris), (Homoptera: Cicadellidae) In The North Central And Eastern United States., K. M. Maredia, M. E. Whalon, S. H. Gage, M. J. Kaeb

The Great Lakes Entomologist

This paper presents available data on the first occurrence dates and the damage severity of the potato leafhopper in the north central and north eastern United States collected during the past 47 years (1951-1997). The data were collected from a variety of sources including: potato leafhopper literature review; published reports; pest alerts; pest surveys; and delphi surveys. First occurrence and severity data show that the arrival time of potato leafhopper and subsequent damage severity varies substantially from year to year. A correlation analysis between date of first occurrence and severity of damage for Michigan, Minnesota, Wisconsin, the north central region …

Density-Dependent And -Independent Behaviors Of The Adult Karner Blue (Lycaeides Melissa Samuelis) (Lepidoptera: Lycaenidae), Ann B. Swengel, Scott R. Swengel

The Great Lakes Entomologist

At 146 pine-oak barrens in central and northwestern Wisconsin USA during 1988-96, 3973 Karner blues (Lycaeides melissa samuelis Nabokov) were found in 95.4 hr of transect surveys during spring and 6896 individuals in 134.8 hr during summer. Of these, 9346 (86%) individuals were first observed copulating, feeding, flushing, flying, or involved in a non-copulatory intraspecific interaction. All these behaviors except copulation showed density-independent influences; all these behaviors also had density-dependent influences. The most frequently significant density-independent variables affecting occurrence of these behaviors were temperature, brood (spring vs. summer), and crepuscularity (time since noon). Male (rather than female or overall) …

Phylloplane Sterilization With Bleach Does Not Reduce Btk Toxicity For Papilio Glaucus Larvae (Lepidoptera: Papilionidae), Laura Haas, J. Mark Scriber

The Great Lakes Entomologist

Neonate tiger swallowtail larvae (Papilio glaucus) were used to bioassay the effects of Btk (Bacillus thuringiensis var. kurstaki) at 4 doses (0.268, 0.034, 0.008, and 0.004 BIU per cm leaf surface) with an untreated control. Larvae, obtained from females captured in Georgia and North Carolina, were fed leaves of either tulip tree (Liriodendron tulipfera) or black cherry (Prunus serotina) in experiments that either included a pre-treatment dip and rinse in 5% chlorox bleach or not, before the application of Btk (dipping leaves in serially diluted solutions of Foray 48B).

The results show no difference between North Carolina and …

Faunal Composition, Wing Polymorphism And Seasonal Abundance Of Some Flea Beetles (Coleoptera: Chrysomelidae) In Southern Quebec (Canada), Claire Levesque, Gilles-Yvon Levesque

The Great Lakes Entomologist

Chrysomelidae (51 taxa) were collected with flight intercept traps from May through October during 1987-1989, in four sites near a raspberry plantation in southern Quebec. More species and individuals of phytophagous flea beetles occurred in two open sites than at a pine woods-raspberry field boundary and in a pine woods. Longitarsus luridus complex, an immigrant taxon in North America, represented 58% of all captures in the two open sites where both Ranunculus acris and Plantago spp. are its main host plants; this species and Longitarsus rubiginosus were almost exclusively represented by jumping apterous adults in pans of flight intercept traps. …

Butterfly (Lepidoptera: Lycaenidae, Nymphalidae, And Satyridae) Faunas Of Three Peatland Habitat Types In The Lake Superior Drainage Basin Of Wisconsin, Jeffrey C. Nekola

The Great Lakes Entomologist

The butterflies which complete their entire life cycle within peatland habitats were documented in the Lake Superior drainage basin of northwestern Wisconsin. Seventy peatlands were inventoried over the course of the 1996 growing season, and were classified as either muskeg, kettlehole, or coastal sites. Muskeg peatlands were of similar elevation to the surrounding uplands, possessed drier and more nutrient-poor substrates, and were typically larger than other peatland types. Kettlehole peatlands were wetter and had floating Sphagnum mats which fringed lake margins or were in depressions much lower than the surrounding uplands. Coastal peatlands were located in estuaries along the Lake …
