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.

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.

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 …

Behavior At A Nesting Site And Prey Of Crabro Cribrellifer (Hymenoptera: Sphecidae), Edward M. Barrows, Patricia L. Lebau, Cathlyn E. Eckstein

The Great Lakes Entomologist

In Michigan, Crabro cribrellifer tends to show nest clumping within a nest aggregation. Its nesting behavior is similar to that of other Crabro, and it preys on Neoitamus flavofemoratus (Diptera: Asilidae) on warm days in July. Miltogrammine flies Metopia campestris are active at the nesting site.

New World Limnichinae Iv. Eulimnichus Casey. A. Synonymies, Lectotype Designations, And Redescriptions (Coleoptera: Limnichidae), David P. Wooldridge

The Great Lakes Entomologist

A recharacterization of Eulimnichus and redescriptions for all previously described species are presented. In most cases, illustrations of the aedeagus are also presented. Seven names are placed in synonymy, and a new name E. impostus, is proposed for E. elongatus (Pic) which is preoccupied. Lectotype designations are made for 10 of the 14 species and one synonymous species.

Effects Of Various Photoperiods On Color And Pubescence In Thyanta Calceata (Hemiptera: Pentatomidae), J. E. Mcpherson

The Great Lakes Entomologist

Rearing immatures of Thyanta calceata in a Iange of photoperiods showed that a threshold photoperiod is involved in the adult dimorphic response (color and pubescence) with the mean threshold near 12.5L: 11.5D. This threshold is consistent with the seasonal distribution of the adult morphs.

A Natural Subgeneric Classification Of Ephemerella Bartoni And Related Species (Ephemeroptera: Ephemerellidae), W. P. Mccafferty

The Great Lakes Entomologist

Phyletic relationships indicate that Ephemerella bartoni Allen should be excluded from the subgenus Dannella in order to prevent a polyphyletic and impractical classifica- tion. A classification in the subgenus Eurylophella is more consistent with the species' phyletic relationships.

Annotated List Of Caddisflies (Trichoptera) Occurring Along The Upper Portion Of The West Branch Of The Mahoning River In Northeastern Ohio, Eric P. Mcelravy, B. A. Foote

The Great Lakes Entomologist

Information is given on the seasonal distribution of 85 species of Trichoptera collected along a small, relatively unpolluted stream in northeastern Ohio.

Annotated List Of Stoneflies (Plecoptera) From Stebbins Gulch In Northeastern Ohio, Martin A. Tkac, B. A. Foote

The Great Lakes Entomologist

(excerpt)

Stebbins Gulch is situated within property owned by The Holden Arboretum in northwestern Geauga County, Ohio, approximately 8.0 km east of the village of Kirtland (Fig. 1). Physiographically, the Arboretum is included within the Southern New York Section of the Appalachian Plateau Province (Feldman et al., 1977). This Section was overridden by several advances of Pleistocene glaciation, the latest of which receded some 13,000 years ago. It is characterized by poorly drained surfaces containing many bogs, ponds, and lakes, except near the Portage Escarpment where small rivers have excavated relatively deep valleys.

Baetis (Ephemeroptera: Baetidae) Of Wisconsin, Edward A. Bergman, William L. Hilsenhoff

The Great Lakes Entomologist

Data on life histories and environmental requirements for species in many mayfly genera remains sketchy at best This is certainly true of Baetis, which is one of the most common components of Wisconsin's lotic fauna. Most Wisconsin streams that are not grossly pobted contain one or more species of the minnow-like nymphs, which are usually found clinging to surfaces of rocks or aquatic plants. Biological studies of Baetis in North America have been neglected primarily because of their enigmatic taxonomy. Even keys of Needham et al. (1935) and Burks (1953), which are considered standard referenas, are either incomplete or difficult …

Incidence And Location Of Eastern Pineshoot Borer Damage In Some Scotch Pine Christmas Tree Plantations In Michigan (Lepidoptera: Olethreutidae), M. Mckeague, G. Simmons

The Great Lakes Entomologist

A survey of Christmas tree farms in Michigan revealed that 26% of the Scotch pine Christmas trees have one or more shoots injured by the eastern pineshoot borer, Eucosma gloriola Heinrich. Most attacks occurred on lateral branches in the top half of the tree. Only 2% of the observed trees had pineshoot borer injury on the terminal leader. Control except for normal shearing, was not recommended for most plantations.

Cereal Leaf Beetle (Coleoptera: Chrysomelidae) Influence Of Seeding Rate Of Oats On Populations, J. A. Webster, D. H. Smith, S. H. Gage

The Great Lakes Entomologist

In field and greenhouse studies, more cereal leaf beetle [Oulema melanopus (Lin- naeus)] eggs and larvae were found per unit area on spring oats, Avena sativa L., planted either at intermediate (54 kg/ha) or high (136 kg/ha) seeding rates, than when planted at a lower seeding rate (14 kg/ha). However, there were fewer eggs and larvae per stem in plantings of the high or intermediate rates than in those of the lower rate. Oats should not be planted at less than the recommended rates in beetle-infested areas.

Phenotypic Expression In The Paper Wasp Polistes Fuscatus (Hymenoptera: Vespidae), Bonnie K. Maclean, Leland Chandler, David B. Maclean

The Great Lakes Entomologist

Quantification of color/color pattern in Polistes fuscatus (Fabricius) revealed that these attributes were the interaction of two antagonistic color sequences; their expression being highly correlated with nest microclimate (relative humidity-temperature). Color/ color pattern expressions were modified under experimental conditions to produce forms having natural counterparts in the field.

Principal coordinates analyses and trend surface analyses using specimens collected throughout the United States indicated three color pattern trends, representing three distinct geographic areas, and, when objectively defined, without intergradation between and/or among areas. It was concluded that fuscatus should not be considered a widespread, polytypic species; rather, as three discrete species: …

A Local Replacement Of Bombus Ternarius By Bombus Terricola In Northern Wisconsin (Hymenoptera: Apidae), James D. Thomson

The Great Lakes Entomologist

During the last few years, the bumblebee Bombus ternarius Say has markedly decreased in numbers in Vilas County in northern Wisconsin while Bombus terricola Kirby has increased. The great ecological similarity of these species suggests that interspecific competition may cause or facilitate this replacement.

A New Species Of Podapolipid Mite, And A Redescription Of Tetrapolipus Blattae (Oudemans) (Acarina: Podapolipidae), Robert W. Husband

The Great Lakes Entomologist

A description of a new species of podapolipid mite, Tetrapolipus oudemansi, associated with the Philippine cockroach, Panesthia angustipennis (Illiger) is presented. Tetrapolipus blattae (Oudemans 19 11) collected from P. angustipennis from Java is redescribed.

A Modified Method For Reading Midges (Diptera: Chironomidae), Peter G. Meier, Henry C. Torres

The Great Lakes Entomologist

A small scale rearing chamber that provides a continuous source of different life stages of Glyptotendipes barbipes Staeger for bioassay studies was developed. A modified glass aquarium containing a substrate of shredded paper hand towels and artificial medium was employed. The amount of protein fed to the larvae can be used to trigger peak emergence, oviposition, and the rate of maturation. Fifty-three egg masses were sampled and 68% were fertile. Ninety-five percent of these hatched and 85% emerged as adults.
