Armour Forse, Joseph B. Mccormick, Susan P. Fisher-Hoch

School of Medicine Publications

We aimed to determine whether aflatoxin dietary exposure plays a role in the high incidence of hepatocellular carcinoma (HCC) observed among Hispanics in South Texas. We measured TP53R249S somatic mutation, hallmark of aflatoxin etiology in HCC, using droplet digital PCR and RFLP. TP53R249S mutation was detected in 3 of 41 HCC tumors from Hispanics in South Texas (7.3%). We also measured TP53R249S mutation in plasma cell-free DNA (cfDNA) from 218 HCC patients and 96 Hispanic subjects with advanced fibrosis or cirrhosis, from South Texas. The mutation was detected only in Hispanic and Asian HCC patients, and patients harboring TP53R249S mutation …

Avian Malaria Among House Sparrows: A Survey Of Disease And Mosquito Vectors (Diptera: Culicidae) In Reed City, Michigan, Luanne R. Gogolin, Jerome E. Freier

The Great Lakes Entomologist

Nine of 350 house sparrows caught in Reed City, Michigan, had malaria parasites detectable on Giemsa-stained thin films. All of the infected birds were juveniles, Parasitemias were too low to permit identification of the Plasmodium present. Collection of potential vector mosquitoes showed that Culex pipiens and Culex restuans were present, but in low numbers.

The Growth And Survival Of Early Instars Of Bellura Obliqua (Lepidoptera: Noctuidae) On Typha Latifolia And Typha Angustifolia, J. M. Penko, D. C. Pratt

The Great Lakes Entomologist

Larvae of the noctuid moth Bellura obliqua are frequently encountered on Typha latifolia, but less commonly on Typha angustifolia. Experiments were conducted to compare the growth and survivorship of early B. obliqua instars on the two species of cattail. In short-term growth chamber experiments there were no significant differences in the survivorship, relative growth rate (RGR), relative consumption rate (RCR), or the efficiency of conversion of ingested food (ECI) between first-instar larvae reared on leaves of the two species. Third-instar larvae fed stems, however, had a greater RGR and higher ECI when reared on T. lalifolia. Differences in growth …

Emergence And Adult Biology Of Agrilus Difficilis (Coleoptera: Buprestidae), A Pest Of Honeylocust, Gleditsia Triacanthos, Rodney C. Akers, Daniel A. Herms, David G. Nielsen

The Great Lakes Entomologist

Emergence and adult biology of Agrilus difficilis were examined in relation to its host Gleditsia triacanthos. began as early as 5 June in 1982 and completed as late as 22 July in 1983. Females lived significantly longer, 48 days, than males, 29 days. Average fecundity was one egg per day during a 36-day oviposition period.

Semiaquatic Hemiptera Of Wisconsin, William L. Hilsenhoff

The Great Lakes Entomologist

Twenty-six species in five families of semi aquatic Hemiptera were collected in Wis­consin and as many as four more may occur. Keys to all of these species are provided along with notes on their distribution, abundance, and identification. Most species were distributed statewide, except that Gerris insperatus and Rhagovelia obesa were most common in the north, and Garris marginatus, Rhagovelia oriander, and Neogerris, Pheumatobates, hestone, were most common in the south. Metrobates, Neogerris, Rheumatobates, Trepebates, Mesovelia, and Rhagovelia apparently overwintered as eggs since adults were absent in the spring. Adults of other genera were collected from early spring to autumn.

A List Of The Odonata Of The La Rue-Pine Hills Ecological Area, T. E. Vogt, J. E. Mcpherson

The Great Lakes Entomologist

A survey of the adult odonate fauna of the La Rue-Pine Hills Ecological Area, Union County, Illinois, was conducted during 1983-1985. Thirty six. species were collected including the damselfly Telebasis byersi Westfall; this damselfly is known to occur in Illinois only at Pine Hills.

Effect Of Beauveria Bassiana On Underground Stages Of The Colorado Potato Beetle, Leptinotarsa Decemlineata (Coleoptera: Chrysomelidae), George E. Cantwell, William W. Cantelo, Robert F. W. Schroder

The Great Lakes Entomologist

Tests were conducted to determine the effect of the fungus Beauveria bassiana (B.b.) on underground of the Colorado potato beetle (CPB), Leptinotarsa decemlineata. Two levels of B.h., g/m2 and 75 g/m2 , were suspended in water and sprinkled over the surface of the ground in cages to which CPB were added, either as overwintering adults or as 4th instar larvae of the 15t generation. Efficacy of treatments was determined by counting emerged adults. Neither level of B .b. increased mortality in overwintering adults. The highest level of B.h. caused a significant decline in emergence of adults from the 1st …

The Influence Of Host Condition On Post First Instar Development Of The Bronze Birch Borer, Agrilus Anxius (Coleoptera: Buprestidae), John Ball, Gary Simmons

The Great Lakes Entomologist

The bronze birch borer is a contributing factor in birch dieback. It is believed that host condition has a major influence on the development of the borer. We found that the host tree's apparent condition does not appear to influence post first instar development.

Parasitism Of Early Instar Jack Pine Budworm (Lepidoptera: Tortricidae) By Apanteles Spp. (Hymenoptera: Braconidae) And Glypta Fumiferanae (Hymenoptera: Ichneumonidae), N. C. Elliott, G. A. Simmons, C. Chilcote

The Great Lakes Entomologist

Glypta fumiferanae and two species of Apanteles parasitized 1st-4th instar jack pine bud worm (Choristoneura pinus). Apparent parasitism of budworm in four Michigan populations ranged from 10.6 to 30.9% for A. fumiferanae, 4.3-16.4% for A. morrisi, and 2.1-9.1 % for G.fumiferanae. A. morrisi probably parasitized 3rd-4th instar jack pine bud worm. Based on the results obtained, it is suggested that sampling overwintering budworm larvae is appropriate for estimating apparent parasitism by A. fumiferanae and G. fumiferanae. Sampling budworm larvae at ca. 500 degree-days (base 8.9°C) is appropriate for estimating apparent parasitism by A. morrisi.

Evaluation Of Pit-Trap Transects With Varied Trap Spacing In A Northern Michigan Forest, Renate M. Snider, Richard J. Snider

The Great Lakes Entomologist

The study compared effects of four distances between traps (range 0.5-4.0 m) on arthropod captures. Twelve traps were aligned in each of four transects, and 20 samples. trap were obtained during summer and fall in a northern Michigan deciduous forest. Catches proved to be unaffected by trap spacing. Rather, they reflected local within-site differences in abundance of dominant species.

Barbaetis: A New Genus Of Eastern Nearctic Mayflies (Ephemeroptera: Baetidae), R. D. Waltz, W. P. Mccafferty, J H. Kennedy

The Great Lakes Entomologist

The new genus Barbaetis Waltz and McCafferty, and new species Barbaetis benfieldi Kennedy are described from larvae collected from the New River, Virginia. Barbaetis is easily told from Baetis by the presence of procoxal osmobranchia. Cladistics of B. benfieldi, related Pseudocloeon species, and the lutheri and pavidus complexes of Baetis are presented and indicate the need for further taxonomic revision. The habitat of B. benfieldi is described in terms of several ecological parameters. The new species demonstrates a univoltine life history with postembryonic development restricted to a short springtime period.

The Great Lakes Entomologist

(excerpt)

In the course of faunistic studies of Indiana Collembola, seasonal occurrences of the two species Hypogastrura packardi (Folsom), 1902 and H. notha (MacNamara), 1922 were found to exhibit seasonal dimorphism and population dynamics similar to those patterns observed in cyclomorphic species previously reported in literature (Leinaas 1981 a,b).

Developmental Rate And Longevity Of Illinoia Pepperi (Homoptera: Aphididae) On Excised Blueberry Leaf Disks, E. A. Elsner, M. E. Whalon

The Great Lakes Entomologist

The aphid Illinoia pepperi is the vector of blueberry shoestring virus, a serious disease of cultivated high bush blueberry. We present a laboratory study of the developmental rate of I. pepperi on excised blueberry leaf discs at different temperatures from 5 to 29°C. Growth rates were lowest at the upper temperature treatments (26 and 29°) and at 10°C. Growth rate and duration in degree-days for each life stage are presented as well as an overall regression equation for development. The lower developmental threshold was calculated at 3.4°C. The results are being used in a phenological management system and an epidemiological …

The Brachycentridae (Trichoptera) Of Wisconsin, William L. Hilsenhoff

The Great Lakes Entomologist

Five species of Brachycentrus and three species of Micrasema were collected. Previous records for Brachycentrus lateralis in Wisconsin are incorrect and should be for B. incanus. but B. lateralis larvae were collected recently in Douglas County. Brachycentrus americanus. B. numerosus. B. occidentalis, Micrasema kluane. M. rusticum and M. wataga usually occurred statewide in unpolluted permanent streams, but were generally absent from southern and eastern agricultural counties where most streams are organically enriched. More than one species and genus frequently occurred in the same stream. with Micrasema larvae often being found in streams with less current than required by Brachycentrus …

Adult Emergence In Two Univoltine Callosamia Promethea Populations: Preponderance Of The Early Emerging Morph In The North And Of The Late Emerging Morph In The South (Lepidoptera: Saturniidae), G. P. Waldbauer, J. G. Sternburg

The Great Lakes Entomologist

Callosamia promethea is common on wild black cherry, Prunus serafina, at the University of Michigan Biological Station in northern lower Michigan. In this area the early emerging morph is preponderant, while to the south in northern Indiana, the late emerging morph is preponderant.

Longevity And Weight Loss Of Free-Flying Male Cecropia Moths, Hyalophora Cecropia (Lepidoptera: Saturniidae), G. P. Waldbauer, J. G. Sternburg, D. H. Janzen

The Great Lakes Entomologist

During their spring flight season, free-ranging male cecropia moths lived a maximum of 12 days (one of 124 recaptured moths of 387 released moths). The number of survivors declined precipitiously after day five; five to seven days is probably the usual life span. The recaptured moths did not have different initial weights than those that were not recaptured. The larger the moth the more absolute weight it lost and the faster it lost weight during the first few days. A moth lost about 20% of its weight during the first night of flight and accumulated about a 40% weight loss …

A New Host Family For Lyroda Subita (Hymenoptera: Sphecidae), Frank E. Kurczewski, Margery G. Spofford

The Great Lakes Entomologist

Lyroda subita, a sphecid that ordinarily stocks its cells with Gryllidae, is reported provisioning a two-celled nest in upstate New York with Tridactylidae. The structure of the nest, depth of celis, stages of wasps, and degree of paralysis of the prey are described.

Nearctic Rhyacionia Pine Tip Moths: A Revised Identity And A New Species (Lepidoptera: Tortricidae), William E. Miller

The Great Lakes Entomologist

Moths now identified as Rhyacionia busckana are a mix of two long-confused sibling species. The name R. busckana applies to the species with male antennal pecten length subequal to antennal segment length. and with female sterigma width threecfold or more ostium bursae width. The name R. granti applies to the previously undescribed species ltype locality Iron Bridge, Algoma District, Ontario) with male antennal pecten length at least two-fold antennal segment length, and with female sterigma width less than three-fold ostium bursae width. Structural differences were discovered after sex attractant studies revealed differences in behavioral physiology and phenology. In the Great …

An Illustrated Key To The Pupae Of Six Species Of Hydropsyche (Trichoptera: Hydropsychidae) Common In Southern Ontario Streams, Jane E. Rutherford

The Great Lakes Entomologist

I present a key for the identification of pupae and pupal exuviae of six species of Hydropsyche that are widely distributed throughout northeastern North America and that are particularly abundant in the streams of southern Ontario. Use of the pupal key requires less manipulation of a specimen than either removing larval sclerites from the pupal case or attempting to discern the adult genitalia through the pupal integument.

Social Feeding Behavior Of Hyphantria Cunea Larvae (Lepidoptera: Arctiidae) In Multiple Choice Experiments, William N. Cannon Jr.

The Great Lakes Entomologist

The response of fall webworm larvae, Hyphantria cunea, to identical feeding stimuli presented in a series of multiple choice tests was studied in the laboratory. Instead of responding independently, all larvae in 61 % of the trials were observed to aggregate at one of two identical feeding stations.
