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. …

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

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 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.
