List Of The Lepidoptera Of Black Sturgeon Lake, Northwestern Ontario, And Dates Of Adult Occurrence, C. J. Sanders 2017 Forestry Canada

List Of The Lepidoptera Of Black Sturgeon Lake, Northwestern Ontario, And Dates Of Adult Occurrence, C. J. Sanders

The Great Lakes Entomologist

From May to September each year from 1960 through 1968, a collection of Lepidoptera was made at Black Sturgeon Lake, northwestern Ontario, from speci­ mens captured in a light trap and from specimens netted during the day. A total of 564 species was recorded from 70 families. A list of the species with dates of capture is presented.


Acorns As Breeding Sites For Chymomyza Amoena (Loew) (Diptera: Drosophilidae) In Virginia And Michigan, Henretta Trent Band 2017 Michigan State University

Acorns As Breeding Sites For Chymomyza Amoena (Loew) (Diptera: Drosophilidae) In Virginia And Michigan, Henretta Trent Band

The Great Lakes Entomologist

Chymomyza amoena is the only chymomyzid fly emerging from white oak acorns in Virginia. An average of 2-3 adult flies emerged from a single acorn in July while emergence declined to 0.4 adults/acorns in September. In fall, Drosophila melanogaster was also present. The incidence of drosophilid (Drosophila, Chymomyza) larvae in parasitized acorns in Virginia (400/0) in autumn was significantly greater than in Michigan (14%). The Chymomyza larvae present in the parasitized acorns in Michigan most likely were C. amoena, from the known adaptation of this species in Michigan to frass-breeding.


Geographic Distribution Of Siphonaptera Collected From Small Mammals On Lake Michigan Islands, William C. Scharf 2017 Northwestern Michigan College

Geographic Distribution Of Siphonaptera Collected From Small Mammals On Lake Michigan Islands, William C. Scharf

The Great Lakes Entomologist

The distribution of ten flea species collected from five small mammal host species on 13 Lake Michigan islands is described. Four new eastern and southern records for Hystrichopsylla dippiei Rothschild are given. Speculative suggestions are made regarding dispersal routes of some of the small mammal host species, and the distribution of flea species from Peromyscus maniculatus gracilis LeConte is dis- cussed in the context of island biogeography theory.


Host Plant Suitability And A Test Of The Feeding Specialization Hypothesis Using Papilio Cresphontes (Lepidoptera: Papilionidae), J. Mark Scriber, Robert V. Dowell 2017 Michigan State University

Host Plant Suitability And A Test Of The Feeding Specialization Hypothesis Using Papilio Cresphontes (Lepidoptera: Papilionidae), J. Mark Scriber, Robert V. Dowell

The Great Lakes Entomologist

The concept that host plant favorites would be used for more rapid and/or efficient growth of the "locally adapted" individuals was tested in a preliminary way using the giant swallowtail butterfly, Papilio cresphontes. Populations feeding only on northern prickly ash, Zanthoxylum americanum (from Wisconsin), primarily (or exclusively) on hoptree, Ptelea trifoliata (in Ohio) and on lime prickly ash, Z. fagara, or Citrus, (in Florida) were compared on alternate hosts and on their actual local hosts under controlled environmental conditions. While the results with final instar larvae generally support the feeding specialization hypothesis with regard to more rapid and/or ...


Acrobasis Shoot Moth (Lepidoptera: Pyralidae) Infestation-Tree Height Link In A Young Black Walnut Plantation, George Rink, Barbara C. Weber, D. Michael Baines, David T. Funk 2017 USDA Forest Service

Acrobasis Shoot Moth (Lepidoptera: Pyralidae) Infestation-Tree Height Link In A Young Black Walnut Plantation, George Rink, Barbara C. Weber, D. Michael Baines, David T. Funk

The Great Lakes Entomologist

Acrobasis shoot moth infestations were evaluated in a young black walnut progeny test for 4 years, from ages 3 to 6. Infestation levels were greatest on the largest trees in the fourth and fifth year after plantation establishment, and were declining by the sixth year. Acrobasis infestation appears to be a problem primarily on young trees less than 2.5 m in height. There was no evidence for genetic resistance to Acrobasis infestation in black walnut.


No Intersexual Differences In Host Size And Species Usage In Spalangia Endius (Hymenoptera: Pteromalidae), B. H. King 2017 Purdue University

No Intersexual Differences In Host Size And Species Usage In Spalangia Endius (Hymenoptera: Pteromalidae), B. H. King

The Great Lakes Entomologist

Spalangia endius were collected from fly pupae, primarily house fly and stable fly, from a poultry house in Indiana. Male and female wasps did not differ within and across host species in host size usage. Also, despite stable fly pupae being significantly smaller than house fly pupae, the proportion of male wasps emerging from the two host species was similar.


Acoustic Signals Of Graminella Nigrifrons (Homoptera: Cicadellidae), S. E. Heady, L. R. Nault 2017 Ohio State University

Acoustic Signals Of Graminella Nigrifrons (Homoptera: Cicadellidae), S. E. Heady, L. R. Nault

The Great Lakes Entomologist

The deltocephaline leafhopper, Graminella nigrifrons, produces low intensity sub- strate transmitted vibrations (signals) to facilitate location of virgin females by males during courtship. In the laboratory, signals produced on maize leaves were received by a phonographic cartridge, amplified, and analyzed on an oscillograph and sonograph. Male calls, that are produced spontaneously, are complex, consisting of three consecutive sections. Section 1 consists of ca. 3 sec of irregular clicks. Section 2 has ca. 4 sec of repeated phrases consisting of a continuous series of 0.4 sec chirps and a roll. Section 3 consists of ca. 5 sec of an intermittent ...


Light Trap Records Of Phyllophaga (Coleoptera: Scarabaeidae) In Wisconsin, 1984-1987, Robert A. Dahl, Daniel L. Mahr 2017 University of Wisconsin

Light Trap Records Of Phyllophaga (Coleoptera: Scarabaeidae) In Wisconsin, 1984-1987, Robert A. Dahl, Daniel L. Mahr

The Great Lakes Entomologist

Phyllophaga adults (June beetles) were surveyed from 1984 through 1987 at five locations in Wisconsin using black light traps. Data were collected at each location for three consecutive years. A total of 9,259 specimens representing 13 species were collected during the survey. Species captured, sex ratios, and flight periods for abundant species were recorded for each location. Species abundance differed from previous surveys of Phyllophaga in Wisconsin. Possible reasons for observed shifts in species abundance are discussed.

Determination Of Frequency And Distribution Of Hessian Fly (Diptera: Cecidomyiidae) Biotypes In The Northeastern Soft Wheat Region, B. H. Chen, J. E. Foster, P. L. Taylor, J. E. Araya, C. Kudagamage

The Great Lakes Entomologist

Fifteen collections of Hessian flies from the northern soft winter wheat region of the United States were used to determine the composition and frequency of biotypes. The wheat cultivars 'Seneca' (H7Hs), 'Monon' (H3), 'Knox 62' (~, H7Hg), and 'Abe' (Hs) were used as differentials. Biotypes J and L replaced biotype B as the prevalent biotype in Indiana, since wheat cultivars having the Hs and the H6 genes have been grown. Biotype GP, the least virulent of any Hessian fly biotypes, was still present in New York indicating that wheat cuItivars with no genes for resistance are still being grown there. The ...


Life Cycles Of Leuctra Duplicata And Ostrocerca Prolongata In An Intermittent Streamlet In Quebec (Plecoptera: Leuctridae And Nemouridae), P. P. Harper 2017 Universite de Montreal

Life Cycles Of Leuctra Duplicata And Ostrocerca Prolongata In An Intermittent Streamlet In Quebec (Plecoptera: Leuctridae And Nemouridae), P. P. Harper

The Great Lakes Entomologist

Large populations of Ostrocerca prolongata and Leuctra duplicata developed in a small intermittent stream in the foothills of the Laurentian Highlands of Quebec. Both species were univoltine in 1974-1975. Ostrocerca prolongata started emerging in mid-to late May. followed by L. duplicata about 2 weeks later. The emergence periods lasted 3-4 weeks with similar patterns in both sexes. Ostrocerca prolongata laid its eggs before the stream dried up in early July. while L. duplicata oviposited just afterward. The eggs of both species did not hatch before October when flow had resumed; the prolonged incubation was due to a diapause in Ostrocerca ...

It is present on thimbleberry, Rubus parviflorus, in three counties in the Upper Peninsula of Michi- gan and in Duluth, Minnesota. It may have arrived on the Keweenaw Peninsula of Upper Michigan within the past ten years. Information about its biology, distribu- tion, and abundance is presented.


Use Of A Monitoring System To Evaluate Pesticide Efficacy And Residual Activity Against Two Pine Root Weevils, Hylobius Pales And Pachylobius Picivorus (Coleoptera: Curculionidae), In Christmas Tree Farms, Lynne K. Rieske, Kenneth F. Raffa 2017 University of Wisconsin

Use Of A Monitoring System To Evaluate Pesticide Efficacy And Residual Activity Against Two Pine Root Weevils, Hylobius Pales And Pachylobius Picivorus (Coleoptera: Curculionidae), In Christmas Tree Farms, Lynne K. Rieske, Kenneth F. Raffa

The Great Lakes Entomologist

Hylobius pales, the pales weevil, and Pachylobius picivorus, the pitch-eating weevil, comprise part of a weevil complex which affects plantation pine production in the Lake States. Common control practices on Christmas tree farms include calendar applications of persistent insecticides. The resulting environmental risks could be minimized by repeating applications only when needed. A sampling method using ethanol-and turpentine-baited pitfall traps was used here to assess the efficacy and monitor persistence of chemical sprays. Trap catch in lindane-treated field plots and untreated controls were compared over two years. Unsprayed controls had significantly higher weevil populations than treated plots. Spray efficacy continued ...


Abundance And Identification Of The Leafmining Guild On Apple In The Mid-Atlantic States, M. W. Brown 2017 USDA

Abundance And Identification Of The Leafmining Guild On Apple In The Mid-Atlantic States, M. W. Brown

The Great Lakes Entomologist

The leafmining guild on apple in the northeastern United States was studied from 1983 to 1988. Ten species of leafminers, all Lepidoptera, were encountered during the sampling. Phyllonorycter spp. (P. blancardella and P. crataegella) were the most ubiquitous and most abundant throughout the region. Lyonetia speculella was also abundant in both managed and unmanaged orchards, indicating a potential to become a pest. Bucculatrix pomiloliella and Coptodisca splendorilerella were abundant in unmanaged orchards, but were only rarely found in managed orchards. Coleophora serratella, Stigmella pomivorella, Parornix geminatella, Tischeria malifoliella, and Recurvaria nanella were also found. A key to the most important ...
