Biology And Ecology Of Melanoplus Borealis (Orthoptera: Acrididae) In Fairbanks, Alaska With Special Reference To Feeding Habits, Tohko Kaufmann

The Great Lakes Entomologist

Overwintered Melanoplus borealis (subspecies, borealis Fieber) eggs hatched within 10-15 days in mid-June. The nymphs molted 5 times and became adults in about 45 days in nature. In both sexes, sexual maturity was attained about 3 weeks after emergence and oviposition started 8-10 days after sexual maturity.

M. borealis is primarily a forb feeder as its mandibular morphology indicates but it also developed and reproduced exclusively on Gramineae in the laboratory.

In the Fairbanks area, Alaska, these grasshoppers were found in sunny open fields where vegetation was short and sparse enough to allow sunrays to penetrate to the ground surface. …

An Assymmetrical Gynandromorph Of Cerotoma Facialis (Coleoptera: Celerucidae), Robert F. Ruppel

The Great Lakes Entomologist

Excerpt: There is a marked sexual dimorphism in beetles of the genus Cerotoma. The female has cylindrical antennal segments; a smoothly convex frons that lacks lobes and subantennal pores, and that is usually dark in color; relatively slender protibia with spurs; nearly cylindrical protarsi 1 without pads; and is somewhat larger than the maIe. The male has depressed and enlarged antennal segments 11 1 and 1V; a white, concave frons with various lobes, enlongate setae, and subantennal pores (a pair of pit-like openings underneath the dorsal lobe); rather swollen protibia without spurs; and enlarged protarsi 1 with ventral pads. …

Studies On The Feculae Of Selected Michigan Acrididae (Orthoptera), Michael Tyrkus, S.K. Gangwere

The Great Lakes Entomologist

Feculae have been used for some years in the study of insect food-habits and biology. Among the past authors who have used them are Frost (1928), Hodson and Brooks (1956), and Morris (1942), who discussed the use of feculae and frass in the identification of insect species in general; Boldyrev (1928), who figured the feculae of the bradyporine katydid Bradyporus multituberculatus; Brown (1937), who described in detail fecular microstructure in the spine-breasted grasshopper Melanoplus bivittatus; Weiss and Boyd (1 950. 1 952), who figured the feculae of representatives of selected insect orders; Gangwere (1 962). who described the …

A Short History Of The Brown-Tail Moth (1782). William Curtis. London: The Curwen Press, 1969. [V], 18, [Ii], 13 Pp. $9.30. Entomological Reprint Specialists, Los Angeles, California., Ronald S. Wilkinson

The Great Lakes Entomologist

Excerpt: This slim volume is easily one of the most attractive entomological reprints that has appeared to date. Most American entomologists are familiar with the story of the "brown-tail moth," Nygmia phaeorrhoea Donovan, the European species which was introducted into Massachusetts in the 1890s and became a serious pest in the northeastern United States and adjoining Canada until appropriate control measures were taken. The Brown-tail is a defoliator of forests, orchards and hedgerows, and as D. S. Fletcher explains in his entomological notes to this reprint, populations of the species periodically build up to epidemic levels and create havoc. Such …

North American Species Of The Genus Hydrochoreutes (Acarina: Pionidae), David R. Cook

The Great Lakes Entomologist

Excerpt: Members of the water mite genus Hydrochoreutes have a Holarctic distribution. They are found in lakes, ponds, and sluggish streams, but usually only in small numbers and therefore long series of specimens are difficult to obtain. Two species, ungulatus (Koch) and krameri Piersig, have a widespread range in Europe and Siberia and the latter species is also known from Algeria. Marshall (1937) reported ungulatus from Maine, Michigan, Wisconsin and California. However, the present author has seen no specimens from North America which can be assigned to the latter species and the illustrations in Marshall's paper are definitely not those …

Storage And Behavior Of Plant And Diet-Fed Adult Cereal Leaf Beetle, Oulema Melanopus (Coleoptera: Chrysomelidae), Stanley G. Wellso, Richard V. Connin, Robert P. Hoxie, David L. Cobb

The Great Lakes Entomologist

The univoltine life cycle of the cereal leaf beetle Oulema melanopus (L.) in Michigan (Castro et al. 1965) is similar to that reported by Venturi (1942) in Europe. Adults emerge from pupal cells in the soil in mid-June to early July, feed voraciously for about three weeks, and enter aestivation sites. For the remainder of the summer and early autumn only a few adults can be found feeding on late-maturing native grasses. The beetles overwinter and usually emerge in late March to early April and resume feeding. Mating and oviposition occur, and larval development is usually completed by late June …

A List Of The Mayflies (Ephemeroptera) In The Michigan State University Entomology Museum, Richard W. Koss

The Great Lakes Entomologist

Excerpt: A fairly extensive collection of Epl~emeroptera representing 35 genera, 1 12 determined species and subspecies is preserved in alcohol in the Entomology Museum at Michigan State University, East Lansing, Michigan 48823. Although most of the specimens were collected in Michigan, the collection also contains representatives of many of the common species found in New England and neighboring Canada. A small portion of the collection is not Northeast in origin.

This list is designed to aid those interested in the fauna of the Northeast and Great Lakes regions, especially if they need specimens for study. I have included the states …

An Account Of Early Regulatory Efforts To Control Cherry Fruit Flies (Diptera: Tephritidae) In Michigan, A.H. Beyer, Murray Hanna

The Great Lakes Entomologist

Excerpt: Fourty years ago, the amount of fruit produced by the cherry industry in Michigan exceeded that of all other states combined. State and federal regulatory agencies permitted no tolerance for maggots in cherries to be used as human food, and when such fruit was found to be infested, it was seized and ordered destroyed. Two species of fruit flies were known to infest cherries in Michigan, Rhagoletis congulata Loew (cherry fruit fly) and R. fausta Osten Sacken (black cherry fruit fly).

Appalachian Orthopteron Relicts In Michigan, Irving J. Cantrall

The Great Lakes Entomologist

Excerpt: I have recently plotted the known Michigan distribution of the various species of Orthoptera which occur in the state (Cantrall, 1968). When this distribution of any single form is compared with its range, it is usually quite clear by what path the insect reached Michigan.

New Or Incompletely Known Species Of Feltria From North America (Acarina: Feltriidae), David R. Cook

The Great Lakes Entomologist

The genus Feltria has a widespread Holarctic distribution. A few species (Lundblad, 1941, 1969) have also been reported from northern Burma but this latter area. as far as its water mite fauna is concerned, might better be considered part of the southern border of the Palearctic, rather than a part of the Oriental Region. Previously. thirty apparently valid species and subspecies of Feltria were known from North America. The present paper describes nine additional forms and brings the total from the Nearctic area to 39, which is nearly identical with the number known from Europe. Most North American species are …

A Key And Annotated List Of The Scutelleroidea Of Michigan (Hemiptera), J.E. Mcpherson

The Great Lakes Entomologist

Excerpt: Although Hussey (1922) compiled a list of the Hemiptera of Berrien County, and Stoner (1922) contributed a list of the Scutelleroidea of the Douglas Lake region, no publications have dealt with Michigan Scutelleroidea on a state-wide basis. However, collections in the Entomology Museum of Michigan State University (MSU), East Lansing, and in the Museum of Zoology of the University of Michigan (UMMZ), Ann Arbor, indicate that collecting has been extensive throughout the state (Fig. 1). The key and annotated list are based on material I identified in these two collections

Eternal Quest: The Story Of The Great Naturalists. Alexander B. Adams. New York: G.P. Putnam's Sons, 1969. 509 Pp. $10.95., Ronald S. Wilkinson

The Great Lakes Entomologist

Excerpt: Alexander Adams seems, if unconsciously, to be following in the footsteps of Donald Culross Peattie. Like Peattie, he wrote a volume on Audubon and then essayed a biographical survey of a number of important naturalists. Eternal Quest is the latter, and interestingly enough, it is the first book of its precise kind since Peattie's Green Laurels (1936) to evoke the same emotion.

Theories On The Nature Of Life. Giovanni Blandino, New York: Philosophical Library, 1969. Xiv, 374 Pp. $6.00., Ronald S. Wilkinson

The Great Lakes Entomologist

In a short span, this encyclopedic work summarizes the historical problems of the nature of life. Blandino conducts his narrative in a condensed and highly-packed form that assumes the nature of an outline. His own ideas are explained in the second part of the book. In the author's words, his conception is that vegetative biological phenomena (1) are material deterministic phenomena and therefore, in order to produce them, fixed laws inherent in matter are both necessary and sufficient...

The Flies Of Western North America. F.R. Cole, With The Collaboration Of Evert I. Schlinger. Berkeley And Los Angeles: University Of California Press, 1969. Xi, 693 Pp. $25.00., George C. Steyskal

The Great Lakes Entomologist

Excerpt: Knowing of the excellence of the author's work especially as an artist of Diptera, entomologists have been waiting for this much-needed volume since the completion of the first manuscript in 1932. The work deals with two-winged flies (Diptera) of North America west of the 104th meridian, south of the 70th parallel and north of Mexico, but including Baja California.

Some Tetranychoid Mites Of Michigan, V. Prasad

The Great Lakes Entomologist

Excerpt: Tetranychoid mites are plant feeders, and many of them are of considerable economic importance. Prior to the present study, only seven species of these mites were known from Michigan; Oligonychus ilicis (McGregor) (McGregor, 1931); Tertranychus mcdanieli McGregor (McGregor, 1931; Pritchard and Baker, 1955); Euryteranychus buxi (Garman) (Ries, 1935; McGregor 1950); Tettranychus atlanticus McGregor (Tuttle and Baker, 1964); Bryobia praetiosa Koch, Panoychus ulmi (Koch), and Tetranychus telarius (L.) (Ghate and Howitt, 1965).

Food Plants Of Some Adult Sphinx Moths (Lepidoptera: Sphingidae), Richard C. Fleming

The Great Lakes Entomologist

Excerpt: While food plants of many species of sphinx moth larvae are well known, food plants of the adults are not. Many observations of the feeding habits of adult sphinx moths undoubtedly have been made, but much of the information is probably resting in the field notebooks and memories of the observers.

To my knowledge no summary of known feeding information has been presented previously for American Sphingidae. A rather thorough list of food plants for adult European sphinx moths has been published by Wahlgren (1941). This list also includes other moth families as well and it can be a …

An Annotated List Of The Spittlebugs Of Michigan (Homoptera: Cercopidae), Murray Hanna

The Great Lakes Entomologist

Excerpt: Representatives of the family Cercopidae are commonly known as "spittlebugs" because the nymphs cover themselves with saliva-like frothy masses composed of bubbles of air trapped by motions of the abdomen in fluids discharged from the alimentary canal. Spittle protects nymphs from desiccation, but they are able to abandon it for brief periods while migrating to new feeding sites or to other host plants where new masses are produced. Gas exchange by nymphs immersed in spittle is accomplished through spiraculae situated in a protective chamber formed on the ventral side of the abdomen by extended tergites.

Biology, Molecular Systematics, Population Dynamics And Control Of A Stem Gall Wasp, Zapatella Davisae (Hymenoptera: Cynipidae), Monica Davis

Doctoral Dissertations

Gall wasps are phytophagous insects that often go unnoticed, however, when they are released from their natural enemies, they have the capacity to outbreak and cause extensive foliar damage. One such outbreaking pest, Zapatella davisae, causes significant damage and mortality to black oak, Quercus velutina. In recent years, black oak decline has been documented in Long Island, New York and coastal New England. Little is known about the lifecycle, distribution or population dynamics of Zapatella davisae and the taxonomy of the species is still unclear. My first study described the biology and distribution of Z. davisae. Zapatella …

You Are What You Eat: Food-Drug Interaction In Honey Bees (Apis Mellifera), Allison G. Kelley, Liao Ling-Hsiu, May Berenbaum

PRECS student projects

The research featured in this poster examined how phytochemicals in nectar and pollen (quercetin and p-coumaric acid), which are known to upregulate cytochrome P450 detoxification enzymes, affect honey bee survival in combination with the pesticides propiconazole, a fungicide, and chlorantraniliprole, an insecticide. While consuming either phytochemical in the absence of pesticides can prolong longevity, consumption of pesticides reduced bee lifespan significantly with or without phytochemicals present.

Elm Seed Bug, Ryan S. Davis

All Current Publications

In July 2014, the Utah Plant Pest Diagnostic Lab and USDA APHIS confirmed the first reported occurrence of elm seed bug (Lygaeidae: Arocatus melanocephalus) in the state of Utah (Fig. 1). A native of Europe, the elm seed bug was first identified in the U.S. in Idaho in 2012. It has since been found in Oregon, Washington, British Columbia, Canada and in various locations throughout Asia and Europe. While Utah’s first submission originated from Salt Lake County, elm seed bug is now widely distributed along the Wasatch Front and Cache Co., and has been reported west to Duchesne Co., east …
