Impact Of The Redheaded Pine Sawfly (Hymenoptera: Diprionidae) On Young Red Pine Plantations, Robert D. Averill, Louis F. Wilson, Richard F. Fowler

The Great Lakes Entomologist

The ecology of the redheaded pine sawfly was studied relative to its impact on red pine plantations. An ecological model, which formed the basis for socioeconomic analysis, was constructed. Because the sawfly prefers trees under moisture stress, damage is most severe in stands growing on sand blows, where there is competition for moisture from bracken fern and hardwoods, and where soils are too moist, too shallow, or too compacted. Outbreaks also appear to be related to dry years. The sawfly has a variable impact on multiple-use values. Because it injures the least productive trees in a stand, timber is only …

A New Method For Exposing Deposit Feeders To Contaminated Sediments For Food Chain Studies, Dale Roberts, Peter G. Meier

The Great Lakes Entomologist

(excerpt)

The ubiquity and refractory nature of certain organic compounds, such as chlorinated pesticides and polychlorinated biphenyls (PCB's), results in their accumulation in aquatic sediments (Holdrinet et al. 1978, Peck et al. 1980, Wang et al. 1979). Their continuous release from this reservoir through physico-chemical and biogenic processes to the overlying water column results in the accumulation of xenobiotic compounds in the food chain.

Genetic Differentiation Among Three Species Of Paradosa (Arachnida: Lycosidae), N. C. Elliott, R. J. Wolff, W. E. Johnson, J. G. Engemann

The Great Lakes Entomologist

Allozymic variation in nine protein producing loci was examined in three species of Pardosa using starch gel electrophoresis. Allozyme frequencies showed a high degree of geographic uniformity among conspecific populations. Estimated heterozygosities for the three species ranged from 0.05 to 0.15. Rogers' coefficients of genetic similarity based on allozyme frequencies averaged over conspecific populations ranged from 0.16 to 0.37 fo rthe three species.

Population Assessment During The Adult Stage Of The Alfalfa Blotch Leafminer, Agromyza Frontella (Diptera: Agromyzidae), D. G. Harcourt

The Great Lakes Entomologist

This paper presents a sampling procedure for estimating adult populations of the alfalfa blotch leafminer, Agromyza frontella (Rondani). The method is based on counts of the flies as they emerge from the soil following adult metamorphosis, taken in a series offurmel traps. Analysis of sampling variability showed that 80 traps per field will give adequate precision for life table studies in alfalfa. The pattern of counts was overdispersed but conformed to the negative binomial distribution.

A Low Cost And Labor Efficient Method For Rearing Black Cutworms (Lepidoptera: Noctuidae), Eli Levine, S. L. Clement, R. S. Schmidt

The Great Lakes Entomologist

The black cutworm, Agrotis ipsilon (Hufnagel), has been and continues to be the subject of many biological and control studies in the north-central states. Interest in this insect can often be traced to its status as a major, but sporadic pest of field com in the region.

Foodplant Suitabilities And A New Oviposition Record For Papilio Glaucus Canadensis (Lepidoptera: Papilionidae) In Northern Wisconsin And Michigan, J. M. Scriber, G. L. Lintereur, M. H. Evans

The Great Lakes Entomologist

(excerpt)

The eastern tiger swallowtail butterfly, Papilio glaucus L., is polyphagous, and has been reported to feed upon plant species of at least 13 families (Scudder 1889, Teitz 1972). The Canadian subspecies, P. glaucus canadensis Rothschild and Jordan, is generally believed to be univoltine, to be devoid of the genetic capacity for dark morph females, and to have morphologically distinct characteristics from the southern subspecies, P. glaucus glaucus L.

Ground Beetles (Coleoptera: Carabidae) Collected By Pitfall Trapping In Michigan Small-Grain Fields, Gary A. Dunn

The Great Lakes Entomologist

(excerpt)

During the 1980 growing season a series of standard, single-cup pitfall traps were maintained in wheat, oat, barley, and rye fields in Michigan. The traps were maintained by Pest Management Field Assistants (PMFAs) and entomology students from Michigan State University. The traps were primarily used to monitor insect pest activity as part of pest management scouting.

(excerpt)

Apache degeerii (Kirby) ranges from Maine south to Florida and west to Iowa and Texas; it has also been recorded from British Columbia and Washington (Metcalf 1945. Wilson and McPherson 1980). This derbid has been recorded from oak, beech, maple, and hickory (Swezey 19(4); otherwise no information on its biology is available.

Large-Scale Production Of Fungal Bait Blocks For The Attraction Of Termites (Isoptera: Rhinotermitidae), R. E. Smith

The Great Lakes Entomologist

It has been shown that wood infected with the brown rot fungus Gloeophyllum trabeum (Pers. ex Fr.) Murr. is'more attractive to termites than sound wood. For several years, small blocks of infected wood have been used as bait to sample soil sites for the presence of termites. The method described here for bait block production is more suitable than the ASTM method for large-scale work.

Impact Of The Spruce Budworm (Lepidoptera: Tortricidae) On The Ottawa And Hiawatha National Forests, 1978-1980, Thomas P. Mog, Ann M. Lynch, J. A. Witter

The Great Lakes Entomologist

The Michigan Impact Plot System was established during 1978 and 1979 to obtain a data base for quantifying the impact of the spruce budworm in the Ottawa and Hiawatha National Forests. The formulae used to estimate the mean, total, and associated standard errors of the various parameters at the national forest and forest district levels are presented. We present the 1978, 1979, and 1980 impact data for the following parameters; percent mortality, total dead volume. dead volume per ha, live volume per ha, defoliation ranking, frequency and extent of top-kill, and incidence of spruce budworm feeding on saplings and regenera- …

Protecting Cows In Small Holder Farms In East Africa From Tsetse Flies By Mimicking The Odor Profile Of A Non-Host Bovid, Rajinder K. Saini, Benedict O. Orindi, Norber Mbahin, John A. Andoke, Peter N. Muasa, David M. Mbuvi, Caroline M. Muya, John A. Pickett, Christian W. Borgemeister

All Peer-Reviewed Publications

Background: For the first time, differential attraction of pathogen vectors to vertebrate animals is investigated for novel repellents which when applied to preferred host animals turn them into non-hosts thereby providing a new paradigm for innovative vector control. For effectively controlling tsetse flies (Glossina spp.), vectors of African trypanosomosis, causing nagana, repellents more powerful than plant derived, from a non-host animal the waterbuck, Kobus ellipsiprymnus defassa, have recently been identified. Here we investigate these repellents in the field to protect cattle from nagana by making cattle as unattractive as the buck. Methodology/Principal findings: To dispense the waterbuck repellents comprising guaiacol, …

The Great Lakes Entomologist

(excerpt)

Our key to Illinois butterflies, exclusive of the skippers (Hesperiidae), was published in 1980. It includes those butterflies listed by Irwin and Downey in their 1973 Illinois checklist plus two species,Anaea aidea (Guerin-Meneville) (Nymphalidae) and Celastrina ebenina Clench (Lycaenidae), added to the state list after 1973.

Survival And Food Detection By First-Instar Melanoplus Femurrubrum (Orthoptera: Acrididae), R. G. Bland

The Great Lakes Entomologist

Newly hatched Melanoplus femurrubrum (DeGeer) were evaluated for survival without food under various moisture, temperature, and light conditions. Although nymphs survived up to 113 h without food, they required food 48-W h after hatching to ensure continued survival and growth. Olfactory food detection was very limited and feeding tended to occur on the first suitable food encountered. Food covered with a ftlm of water and held within several millimetres of the palpi evoked palpal vibrations followed by antennal movements. The evidence suggests that hygroreceptors occur on the pa\pi and pa\pa\ stimulation is necessary before antennal olfaction occurs.

Comparative Behavior Of Pyrellia Cyanicolor (Diptera: Muscidae) On The Moss Splachnum Ampullaceum And On Substrates Of Nutritional Value, David B. Troilo, Randall G. Cameron

The Great Lakes Entomologist

(excerpt)

Entomophily is commonly associated with flowering plants and their pollen vectors, but also occurs in other groups of plants. Among fungi, several genera of Phallaceae offer food rewards to calliphorid and muscid flies, which inadvertently disperse the fungal spores (Ingold 1964). Bryhn (1897) first noted a relationship between various species ofDiptera and members of the moss family Splachnaceae. The nature of this interaction has been the subject of much speculation (Bequaert 1921, Erlanson 1935, Crum et aI. 1972, Koponen and Koponen 1977), but no experimental evidence has been collected.

Redescription Of Micropsectra Polita (Diptera: Chironomidae) With The Female And Immature Stages, Donald W. Webb

The Great Lakes Entomologist

(excerpt)

Malloch (1915) described Micropsectra polita (as Tanytarsus politus) from males collected along the banks of Central Dredge Ditch at Easton, Mason County, llIinois. Females of this species were not collected at that time. On 12 February 1974, males, females, and larvae were collected from a small spring-fed seep (Fig. 1) running into Muncie Pond, in Vermilion County, llIinois.

Foliage from the Leuce section of Populus was rejected for feeding by Chrysomela scripta adults in a choice test involving 12 hybrid poplar clones. Adults showed a feeding preference for the foliage from the Tacamahaca clones when compared to the Aigeiros clones.

Correct Identity Of The Oak Twig Pruner (Coleoptera: Cerambycidae), D. C. L. Gosling

The Great Lakes Entomologist

(excerpt)

The oak twig pruner is a cerambycid of minor economic importance which is generally common through most of eastern North America. The adult beetles oviposit on living twigs of oak and other hardwoods, and the larvae bore within the twig, subsequently pruning it from the tree. Haldeman (1847) identified this borer as Elaphidion villosus (Fabricius), a species later placed in the genus Elaphidionoides by Linsley (1963). This identification has been accepted and followed by Baker (1972), Craighead (1923, 1950), Duffy (1960), Knull (1946). Linsley (1963), and many other authors.
