The Food-Habits And Biology Of Acrididae In An Old-Field Community In Southeastern Michigan, S. K. Gangwere, F. C. Evans, M. L. Nelson

The Great Lakes Entomologist

(excerpt)

Inasmuch as the earth supports a wide variety of terrestrial communities differing in size and species composition, and because no two of these communities are identical in terms of foods and feeders, a correspondingly great complexity of feeding relationships is to be expected. Consequently, food-habit studies must take cognizance of dynamic interplay among many factors which vary with place and time, including that between food availability and the food preferences of consumers. Although ecologists have developed some sophisticated models of the various feeding interactions (e.g., Holling, 1963, 1964, 1966), the number of species whose food-habits and preferences have been …

Description Of The Larva Of Dioedus Punctatus Leconte (Coleoptera: Tenebrionidae), Daniel K. Young

The Great Lakes Entomologist

Larvae of Dioedus punctatus LeConte have been collected from logs, probably Ulmus americana, in the red-rotten stage of decay and determined from reared adults. They are described and illustrated.

The Subcolonization And Buildup Of Tetrastichus Julis, (Hymenoptera: Eulophidae) A Larval Parasitoid Of The Cereal Leaf Beetle, (Coleoptera: Chrysomelidae) In The Lower Peninsula Of Michigan, P. A. Logan, F. W. Stehr, R. J. Sauer

The Great Lakes Entomologist

Following initial establishment of the parasitoid, Tetrastichus julis (Walker), at a carefully managed field nursery, releases of parasitized Oulema melanopus larvae were made by Michigan county agents at preselected sites throughout the lower peninsula during 1970-74. A follow-up recovery program during 1971-75 revealed continued dispersion and population increase for T. julis. An independent census verified the increasing rates of parasitism.

Neurocordulia (Platycordulia) Xanthosoma (Williamson) In Texas (Odonata: Libellulidae: Corduliinae), Curtis E. Williams

The Great Lakes Entomologist

(excerpt)

The rarity of a species is usually judged by the number of specimens in collections, both private and institutional, and the number of places where it has been found or seen. On this basis, Neurocordulia xanthosoma (Williamson) is rare. Its crepuscular habits, its brown coloration, and its habitat requirements, coupled with the habits of most collectors, have been its protection. Nevertheless, because of its apparent special requirements and man's modification of, and encroachment on, its environment, it may soon be a species of the past.

Insects Associated With Michigan Bumblebees (Bombus Spp.), Richard W. Husband, Thomas M. Brown

The Great Lakes Entomologist

(excerpt)

Studies of insect associates of bumblebees are not new. For example, Tuck (1896, 1897) reported over 50 species of insects associated with nests of British bumblebees. Sladen (1912) discussed nest associates and parasites of European bumblebees, and Plath (1934) published similar data for American bumblebees. Postner (1952) published more detailed data. He listed over 60 taxa of insects associated with bumblebees near Erlangen, Germany.

Indiana Ensifera (Orthopera), W. P. Mccafferty, J. L. Stein

The Great Lakes Entomologist

(excerpt)

A total of 67 species of long-horned grasshoppers and crickets were reported to occur in Indiana by Blatchley (1903) in his "Orthoptera of Indiana." Distributional information concerning thek species was sparse and has not been significantly supplemented since that time. Subsequent works which have dealt either heavily or exclusively with the Indiana fauna include Fox (1915), Blatchley (1920), Cantrall and Young (1954), and Young and Cantrall(1956).

Keys And Notes On The Buprestidae (Coleoptera) Of Michigan, Stanley G. Wellso, Gary V. Manley, John A. Jackman

The Great Lakes Entomologist

The distribution and dates of adult activity for Michigan buprestids are discussed. Keys to the genera and species, as well as host information are presented for 116 species and one subspecies. Information on collecting techniques, illustrations of genitalia of 14 species, and scanning electron micrographs of certain structures useful in species identification are presented and discussed. In addition, Pachyschelus confusus, a new species, is described from bush clover.

A List Of The Ants (Hymenoptera: Formicidae) Of The Edwin E. George Reserve, Livingston County, Michigan, Mary Talbot

The Great Lakes Entomologist

(excerpt)

The Edwin S. George Reserve is located in southern Michigan. Here live a very large number of species of ants for an area this far north and consisting of only two square miles. This large number of species is apparently owing to the variety of terrain which has resulted from glacial activity.

Habitats And Populations Of The Ant Stenamma Diecki Emery In Southern Michigan, Mary Talbot

The Great Lakes Entomologist

(excerpt)

The four species of the genus Stenamma recognized for the northeastern United States are all found in the two square miles of the Edwin S. George Reserve, Livingston County, Michigan. They are Stenamma diecki Emery, brevicorne (Mayr), impar Forel and schmitti Wheeler. These ants are not abundant on the George Reserve as they are in certain habitats further north. Near Montreal, Quebec all four are present and diecki, together with Lasius alienus Foerster and L. pallitarsis (hovancher), are the most abundant and widespread species of ants in the woods (Francoeur, 1966; Letendre and Pilon, 1972, 1973).

Abundance Of Insects Inhabiting The Male Strobili Of Red Pine, William J. Mattson

The Great Lakes Entomologist

(excerpt)

Southwood (1973) concluded that pollen feeding was probably the first step in the development of the phytophagous habit in insects, because pollen, compared with plant foliage, is rich in nutrients and low in sewndary defense substances. Surprisingly, little is known about insects that feed mainly on pollen. For example, in a bibliography of insects that feed on reproductive structures of North American conifers (Barcia and Merkel, 1972), less than three per cent of 719 references pertained to pollen feeders. This note reports on the kinds and abundance of insects found inhabiting clusters of fresh staminate or male strobili (MS) …

Genetic Variation In Resistance Of Scotch Pine To Zimmerman Pine Moth, Jonathan W. Wright, Louis F. Wilson, John N. Bright

The Great Lakes Entomologist

(excerpt)

Scotch pine (Pinus sylvestris L.), a forest tree introduced from Eurasia, is commonly planted for Christmas tree and timber use in northeastern United States. In this country it has numerous insect enemies. Among the most important are European pine shoot moth, Rhyacionia buoliana (Schiffermiieller); pine root collar weevil, Hylobius radicis Buchanan;,European pine sawfly, Neodiprion sertifer (Geoffroy); and eastern white-pine shoot borer, Eucosma gloriola Heinrich. Previous studies (Wright et al., 1967; Wright and Wilson, 1972; Steiner, 1974) have revealed large genetic differences in resistance to some of these pests.

Another destructive pest is the Zimmerman pine moth, Dioryctria …

Projected Red Pine Yields From Aldrin-Treated And Untreated Stands Damaged By White Grubs And Other Agents, Richard F. Fowler, Louis F. Wilson

The Great Lakes Entomologist

(excerpt)

Young red pines, Pinus resinosa Ait., during the first few years after planting in the Lake States, are vulnerable to several injurious agents, including white grubs, the larvae of May beetles, Phyllophaga spp. (Kittredge, 1929; Craighead, 1950). The pesticide aldrin3 has frequently been applied at planting time to protect seedlings from white grubs. More than 12,000 acres of national forest land were treated with aldrin from 1960 to 1967 in the Lake States; almost 10,000 of these were on the Hiawatha National Forest (Fowler, 1973).

Curculionidae And Chrysomelidae Found In Aquatic Habitats In Wisconsin, Lutz J. Bayer, H. Jane Brockmann

The Great Lakes Entomologist

(excerpt)

We became interested in aquatic weevils (Curculionidae) and leaf beetles (Chryso- melidae) during the Aquatic Entomology Course at the University of Wisconsin, in the

spring of 1971. Many collections, taken from a variety of aquatic habitats in Wisconsin, contained weevils and leaf beetles. Most of the species were not fully treated in the keys found in aquatic entomology texts. We thought it would be useful to compile keys from the literature and present what is known of the distribution of these insects in Wisconsin. Nine species of weevils have been found in aquatic habitats in Wisconsin, representing seven genera, …

Heptageniidae (Ephemeroptera) Of Wisconsin, R. Wills Flowers, William L. Hilsenhoff

The Great Lakes Entomologist

(excerpt)

Heptageniidae are one of the most abundant and widespread components of Wisconsin's aquatic insect fauna. In almost any stream with a firm substrate and free of gross pollution, the flattened nymphs can be found hiding in crevasses and under rocks, or clinging to submerged wood. Adults and nymphs are easily distinguished from mayflies of other families, nymphs by their dorsoventrally flattened head and dorsal eyes, and adults by their 5-segmented tarsi and complete wing veination. This paper presents our knowledge to date of Heptageniidae in Wisconsin.

Pesticide Effects On Orthopteroid Distribution In Southern Michigan Farmlands, Benedict C. Pinkowski

The Great Lakes Entomologist

The occulrence and abundance of 22 species of orthopteroids is compared for isolated farm yards surrounded by corn fields which were either treated or not treated with a pesticide combination consisting of the herbicides Sutan and AAtrex, and the insecticide Dyfonate. All 22 species were present in the untreated plots, whereas only 12 were recorded in the treated plots, a 45.5% reduction.

Species characteristics determining the observed differences, in the order of decreasing importance, are: general abundance in non-treated areas, seasonal periodism, and vagility. More common species and fewer uncommon species were present in the treated areas, apparently because of …

Three new species, Eosentomon antrimense, E. pinusbanksianum, and Berberentulus mcqueeni, and one new record, E. australicum Womersley are added to the known Protura fauna of Michigan. Further records of E. wheeleri Silvestri, Protentomon michiganense Bernard, Proturentomon iowaense Womersley, Acerentulus confinis (Berlese) and Amerentulus amencanus (Ewing) are listed from various parts of the state.

A New Species Of Neelides (Collembola: Neelidae) From The United States, Ernest C. Bernard

The Great Lakes Entomologist

(excerpt)

This paper is comprised of the description of a new species of Neelides Caroli (1912) recovered from moss. It becomes only the third described species of the genus. Specimens were recovered by a sugar flotation-centrifugation method (Jenkins, 1964), mounted, and characterized with the aid of a camera lucida. The holotype, some paratypes, and five specimens in 95% ethyl alcohol will be deposited in the Entomology Museum, Michigan State University, East Lansing, Michigan, 48824.

A New Genus, Six New Species, And Records Of Protura From Michigan, Ernest C. Bernard

The Great Lakes Entomologist

A new genus, Proacerella (Acerentomidae), and six new species, Proacerella reducta, Eosentomon prutzi, E. sociale, E. pomari, E. brassicae, and Protentomon michiganense are described from various sites in Michigan. Records of previously described species are also listed 'for the species Eosentomon vermiforme Ewing, E. wheeleri Silvestri, Proturentomon iowaense Womersley, Acerentulus confinis (Berlese), Amerentulus americanus (Ewing), and Yamatentomon barberi (Ewing).

Notes On The Biology And Parasitoids Of The Sweet Fern Underwing (Lepidoptera: Noctuidae) In Michigan, Louis F. Wilson

The Great Lakes Entomologist

(excerpt)

The sweet fern underwing, Catocala antinympha (Hubner), sometimes called "the wayward nymph" (Holland, 1968), is one of several lepidopterous defoliators of sweet fern, Comptonia peregrina (L.) Coult. Investigators have dealt only briefly with this insect because it is difficult to collect and rear in quantity and consequently, its biology is poorly known. The early works are basically taxonomic treatises. Barnes and McDunnough (1918b) updated the synonomy which remains intact to date. They placed antinympha as belonging to their Group IV (Catabapta Hulst), a group comprising Myrica (=Comptonia) feeders. Their treatise presents excellent color reproductions of the adult …

Aspects Of The Feeding Behavior Of Scolytus Multistriatus (Marsham) (Scoltytidae: Coleoptera) And Implications For Control, H Riedl, J. W. Butcher

The Great Lakes Entomologist

(excerpt)

Successful protection of elm trees can only be accomplished by means of thorough understanding of the feeding behavior of the smaller European elm bark beetle, Scolytus multistriatus (Marsham). Wolfenbarger and Buchanan (1939) and Whitten (1958) noted that most feeding occurred in the outer portion of the upper crown region, but offered no quantitative data. Therefore, this study was initiated to investigate the regional distribution of feeding injuries along a vertical and horizontal gradient in native American elm, Ulmus americana L.

Rearing Of Scolytus Multistraiatus (Marsham) (Scolytidae: Coleoptera) For Toxicological Experiments, H Riedl, J W. Butcher

The Great Lakes Entomologist

(excerpt)

In a study of the oral and contact toxicity of methoxychlor residues to the smaller European elm bark beetle, S, multistriatus, it is essential to have beetle material available which is of uniform physiological condition and age (Riedl, 197 3). Several rearing containers for bark beetles have been described in the literature (Clark and Osgood, 1964; Fox, 1958; Germain and Wygant, 1967; Schmitz, 1972). A common problem in such containers appears to be fungus growth on the logs due to insufficient ventilation and high humidity. Although these environmental conditions might not cause high mortality, they can render emerging beetles …

Spatial Distribution Of Egg Clusters Of The European Pine Sawfly Neodiprion Sertifer (Geoff.) In Young Pine Plantations In Michigan, Louis F. Wilson

The Great Lakes Entomologist

(excerpt)

The European pine sawfly, Neodiprion sertifer (Geoffroy), is a perennial problem in young pine plantations in Eastern North America. Scotch pine, Pinus sylvestris L., and red pine, P. resinom Ait., are its principal hosts. During recent behavioral studies of this sawfly in Michigan, spatial distribution patterns were determined in order to rapidly survey population levels in young pine plantations (Wilson and Gerrard, 1971). Earlier, Lyons (1964b) presented some distributional data on N. sertifer in regard to population sampling. Wright et al. (1967) and Hattemer et al. (1969) discussed N. sertifer distributions in Scotch pine and mixed pine species provenancz …

Spatial And Seasonal Distribution Of Pine Root Collar Weevil Eggs In Young Red Pine Plantations, Louis F. Wilson

The Great Lakes Entomologist

The pine root collar weevil (Hylobius radicis Buchanan) is a continuous threat to young pine plantations in the northeastern United States and the adjacent Canadian Provinces The female weevil oviposits during the daytime (Wilson, 1968a) near the root collars of red pine (Pinus resinosa Aiton), Scotch pine (P. sylvestris L.), and jack pine (P. hanksiana Lambert), and occasionally other pines. During recent studies on the weevil (Wilson 1968a, 1968b) in Michigan, egg data were taken for use in population and sampling research. Presented here are distribution patterns of eggs within and between trees and throughout the …

Current Classification Of The Families Of Coleoptera, M G. De Viedma, M L. Nelson

The Great Lakes Entomologist

(excerpt)

Several works on the order Coleoptera have appeared in recent years, some of them creating new superfamilies, others modifying the constitution of these or creating new families, finally others are genera1 revisions of the order. The authors believe that the current classification of this order, incorporating these changes would prove useful. The following outline is based mainly on Crowson (1960, 1964, 1966, 1967, 1971, 1972, 1973) and Crowson and Viedma (1964). For characters used on classification see Viedma (1972) and for family synonyms Abdullah (1969). Major features of this conspectus are the rejection of the two sections of Adephaga …

New Techniques For Associating The Stages Of Aquatic Insects, A. V. Provonsha, W P. Mccafferty

The Great Lakes Entomologist

(excerpt)

The immature forms of many benthic insect species are presently either undescribed or unidentifiable. The result is that associations with corresponding adult forms are often necessary in order to confirm specific and sometimes generic identifications. Specific determination of aquatic stages of insects is prerequisite to adequately understanding the various aspects and implications of autecological specificity and the synecological dynamics of an aquatic system. Wiggins (1966), among others, has adequately pointed out the basic necessity of being able to discriminate between immature aquatic species.

A Study In The Summer Phenology Of Dionychious Spiders From Northern Minnesota Forests, Bruce Cutler, Lee H. Grim, H M. Kulman

The Great Lakes Entomologist

Dionychious ground layer spiders from Larix and Populus stands were collected by pitfall traps. The typical pattern of dominant, influent and accessory species was well marked. Populus stands had greater diversity of species than Larix stands. Those species characterized by large male:female sex ratios had sharp peaks in the first month of collecting, and others had smaller early season peaks or early season and late season peaks. Traps with an apron leading to the trap caught twice as many specimens compared to traps without an apron.

The History Of The Name Panorpa Linnaeus (Mecoptera), H. D. Cameron

The Great Lakes Entomologist

(excerpt)

Attempts to understand the origin of Linnaeus' name for the scorpionfly Panorpa have come to nought for a very good reason. The word does not mean anything at all. It is an interesting example of the futility of looking up names in a Latin or Greek dictionary to find their meaning when the history of the word is at all complicated. The word Panorpa is born of a series of taxonomic, philological, grammatical, and (perhaps) typographical errors which can be sorted out by a survey of the pre-Linnaean history of the word and of the insect. In order to …

A Taxonomic And Ecological Study Of The Asilidae Of Michigan, Norman T. Baker, Roland L. Fischer

The Great Lakes Entomologist

Seventy-two species of Asilidae have been recorded from Michigan. An additional seven which may occur are included. Keys to subfamilies, genera and species are given. Two subfamilies and twenty-five genera are represented. A discussion of specific identification, habitat, and distribution is given where possible.

The Laphria canis complex, index complex, and aeatus complex are discussed. One new species, Laphria calvescenta is described. Laphria disparella has been raised from synonymy. Machimus virginicus was removed from Asilus sensu-latu and placed in the genus Machimus.

The Great Lakes Entomologist

(excerpt)

The great majority of specimens, over 12,000 out of 13,185, which form the basis of this study, were collected by the writer during the flight season of the summer of 1963. These are on deposit in the Museum of the Department of Entomology, Purdue University, West Lafayette, Indiana. Other specimens in the collections of the Indiana Department of Natural Resources, Indianapolis, Indiana, of Purdue, and of Earlham College, Richmond, Indiana are incorporated herein. Most specimens in the latter museum were collected, some by the writer, during an earlier general insect survey of the Whitewater River watershed.

Within-Generation Morality Of The Jack Pine Tip Beetle, Conophthorus Banksianae Mcpherson, In Michigan, David J. Hall, Louis F. Wilson

The Great Lakes Entomologist

(excerpt)

The jack pine tip beetle (Conophthorus banksianae McPherson) is a shoot-infesting scolytid hat primarily attacks jack pine (Pinus banksiana Lamb.) in Michigan. The insect was previously thought to be a variant of C. resinosae Hopkins, which attacks cones and shoot tips of red pine. McPherson described C. banksianae as a new species, following life cycle and behavioral studies (McPherson, Wilson, and Stehr 1970; McPherson, Stehr, and Wilson 1970). Separating them by morphological features has been unsuccessful (Herdy 1963).
