An Alternative To Using Fresh Alfalfa For Culturing Colias Philodice Eurytheme Boisduval (Lepidoptera: Pieridae), L. J. Crain, S. J. Roberts, E. J. Armbrust

The Great Lakes Entomologist

Various artificial materials were implemented at each life stage of the alfalfa caterpillar, Colias philodice eurytheme Boisduval, to provide effective and economical replacements for alfalfa. Alfalfa substitutes were used for oviposition and feeding. We also developed a favorable laboratory mating environment. Also, the development of a method for removing disease organisms from eggs without increasing egg mortality was an essential facet of this work. The performance of individuals on artificial surfaces was compared with similar individuals reared on greenhouse alfalfa.

Lice, Mites, And Ticks Of Southeastern Wisconsin Mammals, Omar M. Amin

The Great Lakes Entomologist

Seventeen species of southeastern Wisconsin mammals were found to 6e infected with arthropod ectoparasites other than fleas. One host species was infested with one species of biting lice (Mallophaga), five with five species of sucking lice (Anoplura), ten with at least 16 species of mites (Acari) and nine with six species of hard ticks (Ixodidae). Many new state and/or host records are reported. Host specificity was very pronounced in lice but less marked in ticks and mites particularly in the more common species, ex. Androlaelaps fahrenholzi (Berlese) and Ixodes cookei Packard, respectively.

Lethal Temperatures Of Diapausing Bathyplectes Curculionis (Hymenoptera: Ichneumonidae) A Parasite Of The Alfalfa Weevil (Coleoptera: Curculionidae), Ronald H. Cherry, Edward J. Armbrust, William G. Ruesink

The Great Lakes Entomologist

Seasonally acclimatized diapausing larvae of Bathyplectes curculionis (Thomson) were exposed to extreme hxgh and low temperatu~es to determine lethal temperatures for this stage of the parasite. The possible effects of relative humidity on high temperature mortality, mortality induced by repetitive exposures to sublethal temperatures, and differential survival between sexes, were also measured. The upper lethal temperature for summer larvae was 60°C (LDSo from 2 to 4 h), and the lower lethal temperature for winter larvae was -25°C (LDSo from 0 to % h). Summer larvae showed significantly increased mortality with repetitive exposures to sublethal temperatures (55OC) whereas winter larval mortality …

Feeding Habits Of Wisconsin's Predominant Lotic Plecoptera, Ephemeroptera, And Trichoptera, Theodore J. Shapas, William L. Hilsenhoff

The Great Lakes Entomologist

Feeding habits of nymphs or larvae of 101 species of Plecoptera, Ephemeroptera, and Trichoptera collected from Wisconsin's streams were determined by examining foregut contents. The percent by volume of animal, live vascular plant, filamentous algae, diatom, and detrital material recovered is reported. Plecoptera in the suborder Filipalpia were herbivoredetritivores, and most in the suborder Setipalpia were carnivores. Exceptions were Isoperla bilineata (Say), an omnivore, and Isoperla signata (Banks) and I. slossonae (Banks), both detritivore-herbivores. Except for omnivore Ephemerella cornuta Morgan, Ephemeroptera were detritivore-herbivores. Feeding habits of Trichoptera larvae were diverse. Species of Rhyacophilidae, Polycentropodidae, and Phyrganeidae were all carnivores, while …

Pupa Of Phaleria Rotundata Leconte (Coleoptera: Tenebrionidae), Ian Moore

The Great Lakes Entomologist

(excerpt)

It is not necessary to apologize for making known fragments of the insect fauna of the seabeach of Pacific North America. This fauna commands attention. Among its several aspects are (1) it is linear, extending several thousand kilometers from north to south, but being only a few hundred meters wide, (2) its species are all confined within the seabeach limits, and (3) it is a threatened fauna particularly in southern California where the habitat is being rapidly altered by man for purposes of industry, housing and recreation. P~eservation of specimens from this fauna and recording of observations on its …

A New Species Of Laspeyresia From Michigan (Lepidoptera: Olethreutidae), William E. Miller

The Great Lakes Entomologist

Laspeyresia lacustrina is described from four specimens, all female, captured in flight at two locations in Lower Michigan. On the exterior, the moth most resembles L. populana Busck and several other eastern species; its genitalia most resemble the western L. lautiuscula Heinrich. With wing length 8.4 to 9.4 mm, L. lacustrina is among the largest North American members of the genus.

A List Of The Scutelleroidea Of The La Rue-Pine Hills Ecological Area With Notes On Biology, J. E. Mcpherson, R. H. Mohlenbrock

The Great Lakes Entomologist

A survey of the scutelleroid fauna of the LaRue-Pine Hills Ecological Area, Union County, Illinois was conducted from May, 1972 to September, 1974. Forty-nine species were collected, five of which were state records. The remaining 44 represented over 57% of the species presently listed for Illinois. Life history information was collected for the majority of species, including host plants, predators and parasites. The pertinent literature is summarized for each species.

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).

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, …
