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

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

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 …

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

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

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

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.

A Further Note On Glenosticta Pictifrons (Hymenoptera: Sphecidae) In Michigan, Mark F. O'Brien

The Great Lakes Entomologist

(excerpt)

In a previous paper (O'Brien 1989) I listed a single record of G/enostielia pietjfrons (Smith) from Michigan. The female specimen was from the E.S. George Reserve in Livingston Co., and I stated that it was the only record from the George Reserve.

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. …

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 …

Four new host records for Michigan, four new flea distribution records for the upper peninsula, and 26 new county records are listed.

The Thimbleberry Gallmaker, Diastrophus Kincaidii, (Hymenoptera: Cynipidae), In The Great Lakes Region, Kenneth J. Kraft, Frederic H. Erbisch

The Great Lakes Entomologist

Diastrophus kinccddii, a gall wasp previously known only from California and the Pacific Northwest, is reported from the Great Lakes Region. 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

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 …

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 …

Additional Observations On Tachypompilus Ferrugineus With Emphasis On Male Behavior (Hymenoptera: Pompilidae), Frank E. Kurczewski

The Great Lakes Entomologist

An aggregation of 11 males and 5 females of Tachypompilus ferrugineus was studied during August and September 1989 at a 2 m-high cemetery monument i Syracuse, NY. Male perching behavior and male-male and male-female interactions are described. Male-male interactions included acceptance, perching in close proximity, wing fanning, circling, following, and flight chases. Overt territoriality was not demonstrated by individual males, although several wasps each maintained a few or several stations. Despite noticeable size variation among wasps, there was no dominant-subordinate hierarchy. Male attachment to the cemetery monument waned as the season progressed due to mortality, increased floral feeding, and decreased …

Natural History Of The Common Sooty Wing Skipper, Pholisora Catullus (Lepidoptera: Hesperiidae), In Central Illinois, William C. Capman

The Great Lakes Entomologist

The common sooty wing skipper, Pholisora catullus, has three broods each year in east-central Illinois. Adults are active for only a few hours at mid-day_ Wing color is a rough indicator of age in the field, changing from black to brown over 5 days. These skippers have adult lifespans of about 1 week in the field. Females mate early on their first morning of adult life, and some females mate more than once in their lifetime. Females can lay up to 32 eggs daily, and appear to be able to detect host plants visually over a distance of up …

New Host Plants For Adult Systena Hudsonias (Coleoptera: Chrysomelidae) From Southwestern Virginia, Charles E. Williams

The Great Lakes Entomologist

Adults of the flea beetle, Systena hudsonias, were observed feeding on Ambro- sia trifida and eight previously unrecorded host plants in southwestern Virginia. New host plant records for S. hudsonias include: Arctium minus, Aster nova­ angliae, Chrysanthemum maximum, Eupatorium fistulosum, Helianthus annuus, Rudbeckia hirta (Asteraceae), Mentha spicata (Lamiaceae), and Verbena urticifoiia (Verbenaceae).

New Foodplant And Oviposition Records For The Tiger Swallowtail Butterfly, Papilio Glaucus Canadensis In Alaska (Lepidoptera: Papilionidae), J. Mark Scriber, Matthew P. Ayres

The Great Lakes Entomologist

(excerpt)

The eastern tiger swallowtail butterfly Papilio glaucus L., is the most polyphag­ous of all swallowtails (Lepidoptera: Papilionidae) in the world (Scriber 1984). With a geographic range extending from Florida westward into Texas and north to the Brooks Mountain range in Alaska, and eastward across all of forested Canada, it may also have the largest distribution of any of 563 species of swallowtail butterflies in the world.

Bilateral Differentiation Of Color And Morphology In The Larval And Pupal Stages Of Papilio Glaucus (Lepidoptera: Papilionidae), J. Mark Scriber, Robert H. Hagen

The Great Lakes Entomologist

A sharply delineated, bilateral differentiation of color patterns and morphology were observed in a final (5th) instar larva of a subspecies backcross of a female Papilio glaucus glaucus with a hybrid male (P. g. glaucus x P. g. canadensis). Color and morphological differences were detectable in the pupa as well. In addition, a bilateral size difference was evident in both the pupa and the resulting adult butterfly. Such observations within a single living individual attest to the bilateral independence (also evident in perfect gynandromorphs) and general flexibility of the developmental control in this species of Lepidoptera.

Interaction Of Introgression From Papilio Glaucus Canadensis And Diapause In Producing "Spring Form" Eastern Tiger Swallowtail Butterflies, P. Glaucus (Lepidoptera: Palilionidae), J. Mark Scriber

The Great Lakes Entomologist

The small early "spring form" of the eastern tiger swallowtail butterfly, Papilio glaucus has been described from Massachusetts and Illinois in the north, southward all the way into North Carolina. The wing size, shape, patterns, and color all resemble the northern subspecies, P.g. canadensis. The possibility was explored that the "spring form" could in fact be a reflection of genetic introgression from the northern subspecies into P.g. glaucus populations with laboratory hybrid and back­ cross studies between P.g. glaucus and P.g. canadensis under controlled environments on common foodplants. In addition, morphometric multivariate discriminant analyses of 18 wing characters showed …

Two New Aberrant Forms Of Tiger Swallowtail Butterfly From The Great Lakes Hybrid/Transition Zone (Lepidoptera: Papilionidae), J, Mark Scriber

The Great Lakes Entomologist

Two aberrant forms of the tiger swallowtail butterfly. Papilio glaucus, are described. Both of these aberration types (one in a male, the other in females) are believed to be previously unreported and both are from the Great Lakes hybrid zone and plant transition zone (41 ° _44°N latitude). It is, therefore, possible that genetic introgression from the northern tiger swallowtail P. glaucus canadensis may have been involved in some way with these abnormalities.
