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) …

The Trichoptera Of Panama V. Descriptions Of New Species, New Country Records, And A Synonymy, Brian J. Armitage, Steven C. Harris

Insecta Mundi

The Río Chiriqui basin is one of 52 major watershed areas, or cuencas, in the Republic of Panama. It occurs in western Panama, discharges into the Pacific Ocean, and includes portions of Volcán Barú on its northern extent. The Río Caldera occupies the northernmost subbasin of this basin. Two of its tributaries, Que­brada Grande and Quebrada Jaramillo, occur in close proximity and on opposite sides, and have different recent geologic histories and current land use patterns. During the course of investigating the caddisfly fauna of these two drainages, three new species of the microcaddisfly genus Neotrichia Morton (Trichoptera: Hydroptilidae) were …

A New Genus, A New Species, New Combinations, And Notes On Synonymy And Nomenclature In American Desmiphorini (Coleoptera, Cerambycidae, Lamiinae), Antonio Santos-Silva, James E. Wappes

Insecta Mundi

An early, overlooked description of the genus Atelodesmis (Coleoptera, Cerambycidae, Lamiinae) is attributed to Chevrolat (in Duponchel and Chevrolat 1841), with A. mannerheimii Duponchel and Chevrolat, 1841 as its type species, and the genus redescribed. Atelodesmis Buquet, 1857, is a junior synonym and primary homonym of Atelodesmis Chevrolat. Atelodesmis hirticornis Buquet, 1857 and A. vestita Buquet, 1857 are synony­mized with A. mannerheimii. Fallaxdesmis is described as a new genus with Atelodesmis unicolor Buquet, 1857 as type species. Atelodesmis piperita Bates, 1855 is transferred to Eupogonius and newly recorded for the state of Oaxaca, Mexico. A new species for Mexico …

Evaluation Of Experimental Populations And Glandular-Haired Varieties Of Alfalfa For Alfalfa Blotch Leafminer (Diptera: Agromyzidae) Feeding Injury, R. C. Venette, W. D. Hutchison, E. C. Burkness, C. C. Sheaffer

The Great Lakes Entomologist

Following the spread of the alfalfa blotch leafminer, Agromyza frontella (Rondani) (Diptera: Agromyzidae), into Minnesota and Wisconsin U.S.A. during 1994-1997, three field trials were conducted in Minnesota to assess the potential for leafminer resistance among several sources of alfalfa (Medicago sativa), germplasm. In 1998, 86 entries were evaluated, most of which were experimental populations. In addition, six commercial varieties of alfalfa were evaluated. Of the six varieties, four had been bred for various levels of glandular-hair expression, specifically for resistance to the potato leafhopper, Empoasca fabae (Harris) (Homoptera: Cicadellidae). In two of three trials, we found no significant differences …

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 …
