In 2005, this immigrant Old World species was detected in Michigan for the first time. Twenty-nine adults were found in soybean fields in 4 counties: Ingham, Gratiot, Kalamazoo, and Saginaw.The first individuals were found in Gratiot County on 22 June 2005; we continued to detect individuals until 18 Aug 2005 (2 individuals collected in Saginaw Co.) when sampling ended. Prior to this study, H. variegata had not been known to prey on the soybean aphid, Aphis …

Effects Of Different Habitats On The Productivity Of The Native Paper Wasp Polistes Fuscatus And The Invasive, Exotic Paper Wasp P. Dominulus (Hymenoptera: Vespidae), George J. Gamboa, Julie A. Austin, Kimberley M. Monnet

The Great Lakes Entomologist

We examined the colony productivities of the native paper wasp, Polistes fuscatus (Fab.),(Hymenoptera: Vespidae), and the invasive, exotic paper wasp, P. dominulus (Christ), in oak forest, oak forest-old field ecotone, and old field habitats at the Oakland University Preserve in Rochester, Michigan from 2003 to 2005. Both species of paper wasps exhibited significant differences in colony productivity among the three habitats. Generally, colonies were the most productive in the old field habitat and the least productive in the oak forest habitat.

Colonies of P. dominulus were significantly more productive than comparable colonies of P. fuscatus in all three habitats. There …

New Wisconsin Records For Cyclocephala Lurida (Coleoptera: Scarabaeidae), Nadine L. Kriska, Daniel K. Young

The Great Lakes Entomologist

Cyclocephala lurida Bland (Coleoptera: Scarabaeidae) is a dynastine scarab beetle previously unknown from Wisconsin. Two specimens, one male and one female, were found on the University of Wisconsin-Madison campus. A third specimen was recovered from a blacklight trap in southwestern Wisconsin. Although establishment in the state remains open to question, this species is of potential economic concern as larvae are capable of causing significant damage to lawns, turfgrass, and crops.

Notes On Incidence And Biology Of The Predominant Parasitoids Attacking The Cottonwood Leaf Beetle In Minnesota, Alexander P. Kendrick, Kenneth F. Raffa, Steven J. Krauth, Norman E. Woodley

The Great Lakes Entomologist

Populations of the cottonwood leaf beetle, Chrysomela scripta Fabricius (Coleoptera: Chrysomelidae), in Minnesota were examined for the presence of parasitoids over a period of two years. Field samples of larvae and pre-pupae yielded two parasitoids: a tachinid fly, Cleonice setosa (Reinhard), and a pteromalid wasp, Schizonotus sieboldi (Ratzeburg). Incidence of parasitism by the tachinid was substantially higher than in previous reports, with 32.9% of third instar larvae and 81.4% of pre-pupae being parasitized. The pteromalid was present in 7.0% of pre-pupae. Both parasitoids were reared to adulthood in the laboratory, with the pteromalid exhibiting continued generations, but the tachinid completing …

Linkages Between The Phenologies Of Jack Pine (Pinus Banksiana) Foliage And Jack Pine Budworm (Lepidoptera: Tortricidae), Beresford L. Cadogan, Roger D. Scharbach, Robert E. Krause, Linda S. Sloane, John A. Studens

The Great Lakes Entomologist

A field study conducted in 2001 and 2002 in the Michigan Upper Peninsula investigated seasonal associations between the development of jack pine, Pinus banksiana Lamb., and larvae of the jack pine budworm Choristoneura pinus Freeman (Lepidoptera: Tortricidae). There was almost no active relationship between post-diapause emerging second instars and elongation of vegetative shoots. Early instars were not closely synchronized with the flushing of current-year needle fascicles, which is required to optimize larval feeding. How- ever, there were close feeding and shelter relationships between early instars and year-2 pollen cone development. Associations with, and larval damage to, year-2 seed cones were …

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 …

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) …
