The Great Lakes Entomologist

The 3rd, 4th, and 5th instar nymphs of ltzalana submaculata Schmidt are described from southern Texas. Previously recorded only from Surinam, this is the first record of this fulgorid from the United States and Mexico.

Chemical, Natural, And Cultural Control Of Hyadaphis Tataricae (Homoptera: Aphididae) On Honeysuckle, D. L. Mahr, T. G. Dittl

The Great Lakes Entomologist

Hyadaphis tataricae is an aphid pest of honeysuckle relatively new to the Great Lakes and midwestern regions of North America. Feeding results in severly deformed terminals (witches' brooms). Studies were conducted on natural, chemical, and cultural control. Foliar-applied systemic insecticides provided excellent knock-down and 3-4 weeks of residual control. Although diazinon also provided good knock-down, its residual activity was shorter. Malathion provided suppression but did not protect plants from injury. A tree and shrub soap wash did not provide control. Oxydemeton methyl provided best results of soil-applied systemics. Of 385 aphidophagous predators collected, 85% were syrphid larvae. The remainder were …

Development Of Cranberry Girdler, Chrysoteuchia Topiaria (Lepidoptera: Pyraliadae) In Relation To Temperature, Sherri L. Roberts, Daniel L. Mahr

The Great Lakes Entomologist

The development of Chrysoteuchia topiaria was studied in controlled-temperature chambers. Estimates of the threshold temperatures for the egg, larval, and prepupal-pupal stages were 9.4,6.8, and 9.8°C, respectively. An overall threshold temperature for egg to adult development was estimated to be 8.8°C. Degree-day summations above thresholds averaged 107, 484, and 388 for the egg, larval, and prepupal-pupal stages, respectively.

Scavenging By Jumping Spiders (Araneae: Salticidae), Robert J. Wolff

The Great Lakes Entomologist

Jumping spiders are usually considered obligate predators where ingestion is preceded by visual or tactile stimuli which elicit hunting behavior. Hungry females of Salticus scenicus were shown to feed upon dead houseflies.

Evaluation Of Winter Management Methods To Enhance Survival Of The Giant Salvinia Weevil, Cyrtobagous Salviniae, Lori Robyn Moshman

LSU Master's Theses

Giant salvinia (Salvinia molesta Mitchell) is a noxious aquatic weed in the southeastern United States. Dense plant mats create ecological and economic consequences by displacing native species and impacting freshwater industries. Biological control programs using the salvinia weevil (Cyrtobagous salviniae Calder and Sands, Coleoptera: Curculionidae) have limited efficacy in giant salvinia’s northernmost range due to the weevil’s low cold tolerance and long-term establishment rates. Spunbonded polypropylene (SBP) fabrics and manipulation of plant density were evaluated as two strategies for managing giant salvinia mats during winter. Greenhouse, laboratory, and field experiments were conducted to determine the suitability of these …

Improving The Baculovirus Expression Vector System With Vankyrin-Enhanced Technology, Kendra H. Steele, Barbara J. Stone, Kathleen M. Franklin, Angelika Fath-Goodin, Xiufeng Zhang, Haobo Jiang, Bruce A. Webb, Christoph Geisler

Entomology Faculty Publications

The baculovirus expression vector system (BEVS) is a widely used platform for the production of recombinant eukaryotic proteins. However, the BEVS has limitations in comparison to other higher eukaryotic expression systems. First, the insect cell lines used in the BEVS cannot produce glycoproteins with complex‐type N‐glycosylation patterns. Second, protein production is limited as cells die and lyse in response to baculovirus infection. To delay cell death and lysis, we transformed several insect cell lines with an expression plasmid harboring a vankyrin gene (P‐vank‐1), which encodes an anti‐apoptotic protein. Specifically, we transformed Sf9 cells, Trichoplusia ni High Five …

Georges Brossard, An Advocate For Insects, Stéphane Le Tirant, Brett C. Ratcliffe

Department of Entomology: Faculty Publications

People are strange. They’ve built botanical gardens for plants, planetariums for understanding the planets, zoos for large animals, aviaries for birds, and aquariums for fish, but nothing for insects! It’s as though this class of animals doesn’t count. And yet, of all the creatures on Earth, insects are some of the most important. They are food sources, garbage collectors, decomposers, producers, controllers and pollinators. And what do people do for them in return? We hunt them down with insecticides, pesticides, fungicides and herbicides. It’s time to reconcile humans with insects, a very classy class. I’m going to build a temple …

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 …

Notes On The Genetics Of Phymatodes Testaceus (Coleoptera: Cerambycidae), D. C. L. Gosling

The Great Lakes Entomologist

Phenotype ratio for elytral coloration among reared offspring of Phymatodes testaceus suggests that this trait is controlled by a single gene with a dominant allele producing brown elytra and a reeessive allele for blue elytra. The brown-elytra phenotype previously has been reported as recessive in this species.

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.

Preference For Some Nursery-Grown Hybrid Populus Trees By The Spotted Poplar Aphid And Its Suppression By Insecticidal Soaps (Homoptera: Aphididae), Louis F. Wilson, Lincoln M. Moore

The Great Lakes Entomologist

Susceptibility ranking of more than 50 clones of hybrid Populus whips showed a wide range of attack ranging from none to very heavy. Clones with P. x jackii parentage were the most susceptible, whereas Carolina poplar was unscathed. Growth loss differed little between very heavily aphid-attacked whips and unattacked whips. Two insecticidal soaps adequately controlled the aphid but one caused some phytotoxicity to Populus.

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 …

Effect Of Beta·Exotoxin Of Bacillus Thuringiensis On Development Of The Mexican Bean Beetle (Coleoptera: Coccinellidae), George E. Cantwell, William W. Cantelo, Michael A. Cantwell

The Great Lakes Entomologist

Mexican bean beetle larvae were fed several levels of Bacillus thuringiensis var. thuringiensis that contained the beta-exotoxin to determine if this treatment would extend or prolong their preadult life span. Feeding on bean foliage sprayed with a solution containing 2 g/liter active ingredient diluted I: 10,000, extended the life by 7.5 days. Dilutions of I: 15,000 and 1:20,000 extended the life by over 3 and 5 days, respectively. By extending the time of larval development, enhancement of parasite or predator activity may occur.
