Observations On The Overwintering Potential Of The Striped Cucumber Beetle (Coleoptera: Chrysomelidae) In Southern Minnesota, R. L. Koch, M. A. Carrillo, E. C. Burkness, W. D. Hutchison

The Great Lakes Entomologist

The striped cucumber beetle, Acalymma vittatum (Fabricius) (Coleoptera: Chrysomelidae), is an important pest of cucurbit crops. However, the overwinter- ing capacity of this pest in temperate regions is poorly understood. In this study, the in-field survival of A. vittatum was examined during three consecutive winters. In addition, the supercooling points of A. vittatum were determined as an index of cold hardiness for adults. During each winter, the survival of adults decreased significantly through time, with no individuals surviving until spring. By comparing the supercooling points and in-field survival of adults to soil temperatures, it appears that winter temperatures in Minnesota …

The Great Lakes Entomologist

The pine shoot beetle, Tomicus piniperda (L.) (Coleoptera: Scolytidae), is an exotic bark beetle in North America that was first found in the Great Lakes region in 1992. We evaluated T. piniperda reproduction and development in one Eurasian pine (Scots pine, Pinus sylvestris L.) and three North American pines (jack pine, P. banksiana Lamb.; red pine, P. resinosa Ait.; and eastern white pine, P. strobus L.) under laboratory conditions. We introduced one pair of adults into individual pine bolts, allowed development, collected brood, and later debarked all bolts and measured galleries. Reproduction and development occurred in all pine species tested. …

Impact Of Simulated Insect Defoliation And Timing Of Injury On Cabbage Yield In Minnesota, Eric C. Burkness, Gloria J. Gingera, W. D. Hutchison

The Great Lakes Entomologist

In 1992 and 1994, field studies were done to assess the tolerance of transplanted cabbage to simulated insect defoliation and to determine if the defoliation level and growth stage at which defoliation begins influences final yield. In both years, 6 defoliation levels ranging from 0-100% were applied to transplanted cabbage at 4 time intervals. The time intervals began at transplanting, pre-head and head stages and continued until either head stage or harvest. For both years, the only time interval with significantly higher yield than the trans- plant to harvest interval (longest interval) was the head to harvest interval (shortest interval) …

Anatomy And Histology Of The Male Reproductive Complex Of The Onion Maggot Fly, Delia Antiqua, (Diptera: Anthomyiidae) Including Some Comparisons With D. Platura And D. Radicum, Karin A. Grimnes, James R. Miller

The Great Lakes Entomologist

In Delia antiqua (Meigen) (Diptera: Anthomyiidae), the male reproductive complex is composed of a pair of testes, paired vas deferens connecting the testes to the anterior ejaculatory duct, and a pair of paragonial (accessory) glands. Each D. antiqua paragonial gland consists of a single layer of secretory epithelial cells surrounded by a thin sheath of muscle tissue. The paragonial cells appear to be largely homogeneous in form, however a minor number of cells exhibit unique staining characteristics distinct from the main cells of the gland. This is preliminary evidence for a secondary cell type as has been found for Drosophila …

Disruptant Effects Of 4-Allylanisole And Verbenone On Tomicus Piniperda (Coleoptera: Scolytidae) Response To Baited Traps And Logs, Robert A. Haack, Robert K. Lawrence, Toby R. Petrice, Therese M. Poland

The Great Lakes Entomologist

We assessed the inhibitory effects of the host compound 4-allylanisole (release rates = 1 and 2 mg/d in 1994, and 1 and 10 mg/d in 2001) on the response of the pine shoot beetle, Tomicus piniperda (L.), adults to funnel traps baited with the attractant host compound α-pinene (release rate = 150 mg/d) in two pine Christmas tree plantations in Michigan in spring 1994 and two other plantations in spring 2001. In three of the four plantations, all doses of 4- allylanisole significantly reduced T. piniperda attraction to α-pinene-baited traps by 46 to 76%. We also tested the inhibitory effect …

Behavior And Activity Patterns Of The Black Scavenger Fly, Sepsis Punctum (Diptera: Sepsidae), Near A Permanent Dung Source, Beth E. Leuck

The Great Lakes Entomologist

The behavior of the black scavenger fly Sepsis punctum (L.) (Diptera: Sepsidae) was studied on satellite resource (dung) patches established near a pig pen. Flies were most numerous on the patches when ambient temperature and light conditions were high. Females were commonly found on the patches and males occupied boards surrounding the patches where they displayed vigorously to other males and females. Approximately four times as many females as males occurred on the patches. Females were larger than males, and paired males were larger than unpaired males. Males did not exhibit precopulatory guarding as reported in Sepsis cynipsea (L.) and …

Investigating The Ecology Of The Mound-Building Ant, Acanthomyops Claviger (Hymenoptera: Formicidae), In Re-Created Prairie, Chris E. Petersen, Ana Krstic, Judith C. Morgan, Kenneth Mccallum, Renee E. Petersen
