Effects Of Salmon Spawning Activity On Macroinvertebrates In A Small Michigan Stream, Douglas L. Denison, Peter G. Meier

The Great Lakes Entomologist

Density and composition of macroinvertebrate populations were examined prior to and during the migration and spawning of coho and chinook salmon in a small stream in Michigan. Data gathered from bottom samples indicated that disruption of substrate in the experimental area resulted in a significant decrease in the numbers and species of the macroinvertebrate community. This reduction of invertebrates can create a severe stress on native trout populations.

Additions To The Checklist Of The Illinois Spiders, J. A. Beatty, J. M. Nelson

The Great Lakes Entomologist

Five families and 140 species of spiders not included in former Illinois checklists are recorded. Two of these families, Antrodiaetidae and Scytodidae, and 40 of the species have been cited in earlier revisionary or other literature. The families Oonopidae, Symphytognathidae (slat.) and Ctenidae, and the remaining 100 species of spiders are recorded from Illinois for the first time. Locality data are given as counties only, and months of capture of mature specimens are presented. The total known spider fauna of Illinois now stands at 500 species in 27 families.

An Outbreak Of The Saddled Prominent Caterpillar, Heteocampa Guttivitta (Lepidoptera: Notodontidae) On Beaver Island, Michigan, Alice Loesch, Jeffry Foran

The Great Lakes Entomologist

(excerpt)

In 1975 and 1976 an outbreak of the saddled prominent caterpillar, Heterocarnpa guttivitta (Walker) was observed in Beech-Maple climax forests on Beaver Island, Michigan. The adult guttivitta moths emerge in late May and early June, mate, and lay small (1 mm) eggs on the underside of leaves. One female lays about 500 of the green spheres. In 9-10 days the eggs hatch, and the larvae go through characteristic changes in form and markings through the following five instars (Allen, 1972).

Diagnoses, Distribution, And Comparative Life History Notes On Aaroniella Maculosa (Aaron) And A. Eertmoedi N.Sp. (Psocoptera: Philotarsidae), Edward L. Mockford

The Great Lakes Entomologist

Two species formerly confused under the name Aaroniella maculosa (Aaron) are separated in all life history stages. Application of the name maculosa was determined by examination of the type. The other species is new and is named (A. eertmoedi) and described. It is parthenogenetic, apparently with no males. The ranges of the two species are largely distinct but show some overlap.

Observations Of The Habits Of Lygaeus Kalmii Angustomarginatus (Hemiptera: Lygaeidae) In Southern Michigan, Linda-Margaret Hunt

The Great Lakes Entomologist

Lygaeus kalmii Stal (Hemiptera: Lygaeidae) is an insect found throughout the eastern United States and Canada. There is extensive taxonomic literature on this insect (Stil, 1874; Townsend, 1887; Parshey, 1919, 1923; Slater and Knopf, 1969), but very little attention has been given to the rest of its biology. This study describes the habits of kalmii populations in southern Michigan.

Additions And Corrections To The List Of Michigan Pentatomoidea (Hemiptera), J. E. Mcpherson

The Great Lakes Entomologist

Six new species are added to the 1970 list of Michigan Pentatomoidea, and two are deleted.

Effects Of Various Photoperiods On Morphology In Euschistus Tristigmus Tristigmus (Hemiptera: Pentatomidae), J. E. Mcpherson

The Great Lakes Entomologist

Rearing immatures of Euschistus tristigmus tristigmus in a range of photoperiods showed that a threshold photoperiod is involved in the adult dimorphic response (shoulder shape and number of midventral abdominal spots) with the mean threshold probably near 14.5L:9.5D (light: dark). This threshold is consistent with the seasonal distribution of the adult morphs.

Susceptibility And Injury Of Some Hybrid Walnuts By The Butternut Curculio (Coleoptera: Curculionidae), Louis F. Wilson, Jeffrey A. Corneil, Walter A. Lemmien

The Great Lakes Entomologist

The butternut curculio, Conotrachelus juglandis LeConte (Coleoptera: Curculionidae), injures the shoots and nuts of various species and hybrids of Juglans in eastern North America. This insect was described in 1876 (LeConte, 1876); its life history has been studied in Connecticut (Britton and Kirk, 1912) and in West Virginia (Brooks, 1922). Its range, however, extends from the New England states through southern Canada to the Great Plains and south to Kansas, Alabama, and Georgia, contiguous with the natural range of butternut (J. cinerea), its native host.

Thirteen new species of Eulimnichus are described: Eulimnichus visendus, corrinae, langleyae, coheni, improcerus, pellucidus, sharpi, incultus, rugulosus, nrsticus, acutus, subitus, and spangleri. A key to the 27 known species is included.

Two Observations Of Predation On Lepidoptera, Irwin Leeuw

The Great Lakes Entomologist

(excerpt)

During the early afternoon of 25 August, 1977, a large European mantid, Mantis religiosa Linnaeus, was observed feeding on an adult male monarch butterfly, Donaus p. plexippus Linnaeus (Danaidae) while clinging to the flower head of a blazing star plant (Liatris sp.) on a cactus prairie at the Allegan State Game Area, Allegan County, Michigan.

Collecting Neocurtilla Hexadactyla, The Northern Mole Cricket (Orthoptera: Gryllidae), In Iowa, J. R. Dewitt

The Great Lakes Entomologist

(excerpt)

The northern mole cricket, Neocurtilla hexadactyla (Perty), is a common insect that is infrequently collected perhaps owing to its burrowing and nocturnal habits. It tunnels into moist soil and feeds on tender roots, earthworms, or various insect larvae (Blatchley, 1920).

Notes On Mayfly Nymphs From Northeastern Minnesota Which Key To Stenonema Vicarium (Ephemeroptera: Heptageniidae), Thomas M. Lager, Philip A. Lewis

The Great Lakes Entomologist

(excerpt)

A review of the literature indicates that Stenonema vicarium (Walker) adults have not been collected from northeastern Minnesota. However, mayfly nymphs which key to that species, based on the descriptions in Lewis (1974), have been collected from many streams in the area which are also inhabited by nymphs of the closely related species, Stenonema fuscum (Clemens).

Fall Termination Of Aestivation And Field Dispersal Of The Alfalfa Weevil (Coleoptera: Curculionidae) In Illinois, R. J. Barney, S. J. Roberts, R. D. Pausch, E. J. Armbrust

The Great Lakes Entomologist

Emergence traps, flight traps, sweeping, and egg sampling were employed to determine fall termination of aestivation of the alfalfa weevil, Hypera postica, and patterns and timing of field reentry, and subsequent fall oviposition. Adult alfalfa weevils were found to terminate aestivation in wood edge field borders in mid-late October. Field reentry began in late October as a gradual process, starting at wooded field borders, with the field population equally dispersed by mid-November.

Two Trapping Systems To Determine Incidence And Duration Of Migration Of Adult Alfalfa Weevils, Hypera Postica (Coleoptera: Curculionidae), S. J. Roberts, R. D. Pausch, E. J. Armbrust, R. J. Barney

The Great Lakes Entomologist

Emergence and flight traps were used to study the pre- and post-diapause movements of the alfalfa weevil, Hypera postica. The emergence traps proved to be an excellent tool in determining the time of diapause termination and in providing an accurate accounting of the number of weevils per unit area in aestivation sites. The flight traps showed when diapause flights to and from alfalfa fields took place. Both trapping systems can be utilized in a pest control program to locate more closely where the alfalfa weevil aestivates and when diapause related movements occur.

Alternatives To The Gypsy Moth Eradication Program In Michigan, Joseph G. Morse, Gary A. Simmons

The Great Lakes Entomologist

Responding to questions of what the gypsy moth, Porthetria dispar, would do in Michigan forests, a computer simulation model was constructed. The model consisted of three subunits: a submodel of gypsy moth population dynamics, a submodel of forest growth and a submodel of tree defoliation and mortality. Several different policies were simulated for an 80 year period. The eradication policy now employed in Michigan failed due to survival of small portions of the population. Allowing the gypsy moth to become established in Michigan forests and then responding by spraying when defoliation is visible provided a policy with the least …

New Species Of Sminthuridae From North America (Collembola: Symphypleona), Richard J. Snider

The Great Lakes Entomologist

(excerpt)

This account is the result of efforts by Drs. Kenneth Christiansen and Peter Bellinger to amass and examine the major collections of North American Collembola. Their work will culminate in a descriptive monograph on the Collembola-fauna of North America. The author agreed to describe part of the new species of Sminthuridae extracted from those collections. The analysis of specimens justifies erection of 17 species new to science.

The Life Cycle Of The Mayfly Stenacron Interpunctatum (Ephemeroptera: Heptageniidae), W. P. Mccafferty, B. L. Huff Jr

The Great Lakes Entomologist

Larval growth and development of Stenacron interpunctatum was studied for a one year period at Wildcat Creek, Indiana. Analysis of developmental stages and sue classes revealed three broods at different degrees of maturation at any one time of year. Broods emerged in early spring, mid-summer, and late summer-early fall, respectively; the former two overwintering in different stages of larval development, and the latter completing development in one growing season in warm temperatures and maturing at relatively smaller sizes. The population possessed a complex life cycle ranging from one generation per year to three generations every two years. General sampling over …
