(excerpt)

The authors are to be commended for producing an extremely useful and thoroughly complete compilation of this fascinating but frequently ignored group of Lepidoptera. Itis, without a doubt, the finest state systematic check- list that this reviewer has previously read and one that will probably not be exceeded in the near future. This monograph, a systematic checklist of the owlet moths (Noctuidae) of Ohio, is the second monograph to present the lepidopterological results of a cooperative effort among the Ohio Biological Survey, the Ohio Lepidopterists, and the Ohio Department of Natural His- tory. It follows a very comprehensive survey …

First Records Of Gomphaeschna Furcillata And Anax Longipes In Wisconsin (Odonata: Aeshnidae), K. J. Tennessen

The Great Lakes Entomologist

(excerpt)

The two new records of Odonata reported here for Wisconsin are north- western range extensions for each species.

The genus Gomphaeschna Selys contains two species, antilope (Hagen) and furcillata (Say), the distributions of which are limited to eastern North America. Gomphaeschna antilope ranges from New Jersey west to Ohio and south to Louisiana and Florida (Needham and Westfall 1955). Gomphaeschna furcillata is similarly distributed in the south, but ranges further north, to Nova Scotia and Maine eastward, and to Michigan westward.

Ixodes Dentatus (Acari: Ixodidae) In Michigan: First State Records And Occurrence On A Human, Edward D. Walker, Melvin L. Poplar, Howard L. Russell

The Great Lakes Entomologist

An Ixodes dentatus adult female was taken from a cottontail rabbit in Kalamazoo County, and a nymph from a child in Berrien County, in 1992 in Michigan. These findings represent the first records of I.dentatus in the state, and document an unusual parasitization of a human being by this species of tick.

Carnivory In Adult Female Eumenid Wasps (Hymenoptera: Vespidae: Eumeninae) And Its Effect On Egg Production, Charles F. Chilcutt, David P. Cowan

The Great Lakes Entomologist

Seventy captive adult female wasps of the eumenid genera Ancistrocerus and Euodynerus were observed to feed on multiple prey items. It was shown experimentally that E. foraminatus females that fed on prey had significantly larger egg volumes than adult wasps deprived of prey.

Comparative Aspects Of Mating Behavior Patterns In Six Species Of Stink Bugs (Heteroptera: Pentatomidae), Lee C. Drickamer, J. E. Mcpherson

The Great Lakes Entomologist

Mating sequences were analyzed for six species of stink bugs using video- tapes. The results consisted of qualitative descriptions of the precopulatory activities of the pairs and quantitative analyses of the number and direction of mating sequences, including the latency to and duration of copulatory lock. It was possible to quantitatively characterize each of the six species tested. In addition, certain infrequent behavior patterns, e.g., head butts, were observed for some species and not others. The results extend the previous information on mating activities in stink bugs, particularly for Euschistus. We interpret our findings with regard to reproductive strategies …

Epigeal And Flight Activity Of Coleoptera In A Commercial Raspberry Plantation And Adjacent Sites In Southern Quebec (Canada): Introduction And Nitidulidae, Claire Levesque, Gilles-Yvon Levesque

The Great Lakes Entomologist

We studied the epigeal and flight activity of Coleoptera in a commercial raspberry plantation and adjacent sites in southern Quebec, from 1987-1989. In this first paper, we present the results for the Nitidulidae. Pitfall traps yielded 521 beetles representing 15 species; Glischrochilus quadrisignatus represented 86% of catches in raspberry rows (old and young plants), and Epuraea spp. were the most abundant nitidulids in a woods-field boundary and in a pine woods. Nitidulids in flight interception traps comprised 2179 individuals of 28 species; Meligethes nigrescens was the most abundant species in open sites around the raspberry plantation, while Epuraea avara and …

Ecological Observations On Predatory Coccinellidae (Coleoptera) In Southwestern Michigan, K. M. Maredia, S. H. Gage, D. A. Landis, T. M. Wirth

The Great Lakes Entomologist

Ecological observations on habitat utilization by thirteen species of predatory Coccinellidae were made at a southern Michigan site during 1989 and 1990. Most of species were common during both years and used both agricul- tural and uncultivated habitats. Coccinella septempunctata and Coleomegilla maculata, were the most abundant in agricultural crops (alfalfa, maize, soy- bean and triticale), whereas Adalia bipunctata and Cycloneda munda, were the most abundant in deciduous and bushy habitats.

Factors Influencing Oviposition In Aedes Triseriatus (Diptera: Culicidae), Jeffrey Beehler, Sharon Lohr, Gene Defoliart

The Great Lakes Entomologist

Five factors associated with natural oviposition sites were tested for their attractancy to ovipositing Aedes triseriatus, including dyed oviposition water, presence of decaying organic matter, a dark oviposition container, water in which conspecific larvae have been reared to the 4th instar and the presence of eggs on the balsa wood oviposition substrate. A replicated fractional factorial design was used to examine the effects of the above factors on oviposition behavior in laboratory experiments. Regression analysis showed dyed oviposition water and eggs on the oviposition substrate to be statistically significant attractants for ovipositing A. triseriatus females. The attraction to dyed …

Effects Of Neighboring Nectar-Producing Plants On Populations Of Pest Lepidoptera And Their Parasitoids In Broccoli Plantings, J. Z. Zhao, G. S. Ayers, E. J. Grafius, F. W. Stehr

The Great Lakes Entomologist

Eggs and larvae of the imported cabbageworm, Pieris rapae, were much more abundant in broccoli interplanted with nectar-producing plants than in broccoli monoculture. More diamondback moth larvae, Plutella xylostella, occurred in broccoli interplanted with or adjacent to nectar-producing plants than in broccoli monoculture. Density of cabbage looper larvae, Trichoplusia ni, was similar among the three types of broccoli plantings. For Cotesia rubecula, established in Michigan after introduction from Yugoslavia, pupae were more numerous in broccoli interplanted with nectar-producing plants than in other plots. High parasitism rates of diamondback moth, mainly by Diadegma insulare, were observed in …

Suitability Of Selected Broad-Leaved Weeds For Survival And Growth Of Two Stalk-Boring Hydraecia Species (Lepidoptera: Noctuidae), Bruce L. Giebunk, J. Mark Scriber, John L. Wedberg

The Great Lakes Entomologist

Third instar hop vine borer (Hydraecia immanis) and potato stem borer (H. micacea) are new pest species on corn in the Midwest. Early instar larvae feed on small-stemmed grasses, and later instar larvae switch to broad- stemmed hosts to complete development. In order to assess potential suitability of various weeds of corn fields, larvae were reared on seven selected broad- leaved plants for 16-18 days under greenhouse conditions to determine their feeding behavior and performance. Domestic plants included hop (Humulus lupulus) and potato (Solanum tuberosum); weed species included curly dock (Rumex crisp us), redroot pigweed …

Effects Of Aspen Phenolic Glycosides On Gypsy Moth (Lepidoptera: Lymantriidae) Susceptibility To Bacillus Thuringiensis, Gavin E. Arteel, Richard L. Lindroth

The Great Lakes Entomologist

Performance of the gypsy moth, Lymantria dispar, on quaking aspen, Populus tremuloides, is strongly affected by foliar concentrations of phenolic glycosides. Because the microbial insecticide Bacillus thuringiensis is widely used against gypsy moths and has a mode of action similar to that of phenolic glycosIdes, we investigated the combined effects of the two toxins on gypsy moth larvae. The experimental design was a 2 x 2 factorial: two levels (0, +) of phenolicglycosides for each of two levels (0, +) of B. thuringiensis. The toxins were incorporated into artificial diets and bioassayed against first and fourth instars. …

The Great Lakes Entomologist

(Excerpt)

The Grand Traverse Region of Lower Michigan is of special interest zoo- geographically in that it includes the northernmost known localities for various species of organisms characteristic of the Carolinian Biotic Province (Douglass 1977, 1983; McCann 1979).

Control Of Aphids On Spring Oats And Winter Wheat With Slow Release Granular Systemic Insecticides, Jaime E. Araya, Sue E. Cambron

The Great Lakes Entomologist

Aphid infestations (Homoptera: Aphididae) on spring oat (Avena sativa) cv. 'Ogle', and during the fall on winter wheat (Triticum aestivum) cv. 'Clark', composed mainly of Rhopalosiphum padi and Macrosiphum avenae, were reduced with applications at the 2-3 leaf stage of slow release granular formulations of acephate, carbofuran, and disulfoton, compared with carbofuran 15G and untreated controls, in field trials during 1990-1991 in northwestern Indiana. These field results corroborated those obtained by previous studies with the same formulations and dosages in the laboratory.

In oat, all insecticide treatments reduced aphid populations and percent- age aphid~infested plants, …

Detection Of Prolonged Diapause Of Northern Corn Rootworm In Michigan (Coleoptera: Chrysomelidae), D. A. Landis, E. Levine, M. J. Haas, V. Meints

The Great Lakes Entomologist

Prolonged diapause of northern corn rootworm, while known from other Midwestern states, has not previously been reported in Michigan. Populations of northern corn rootworm, (Diabrotica barberi) from two first-year corn fields in Genesee County, Michigan were examined for prolonged egg diapause. Pro- longed diapause was suspected in these populations due to an unusually high proportion of northern versus western corn rootworms in these fields. Eggs obtained from females collected at these sites were reared in the laboratory for two years. The presence of the prolonged diapause trait was confirmed in one population by eggs which hatched following two …

Riffle Beetles Of Wisconsin (Coleoptera: Dryopidae, Elmidae, Lutrochidae, Psephenidae) With Notes On Distribution, Habitat, And Identification, William L. Hilsenhoff, Kurt L. Schmude

The Great Lakes Entomologist

Twenty-four species of Elmidae, three species of Psephenidae, two species of Dryopidae, and one species of Lutrochidae were represented among 33,351 riffle beetles that were identified from Wisconsin. Almost all were found in streams, but some inhabited wave-swept lake margins and spring-ponds. Adults and larvae of eight species were collected almost exclusively from submerged, decaying wood, while those of most other species inhabited rock or gravel substrates, especially in stream riffles, and only occasionally were found in wood; adults of three species of Dubiraphia were found also on macrophytes. The presence of Stenelmis antennalis, S. fuscata, and S. …

Ontogeny And Systematics Of The Genus Cerophagus (Acari: Gaudiellidae), Mites Associated With Bumblebees, Barry M. Oconnor

The Great Lakes Entomologist

Nymphs and adults of Cerophagus nearcticus n. sp. are described from the nest of Bombus terricola occidentalis in California and phoretic associations with B. impatiens in Michigan and New York. On the basis of adult morphology, the genus Cerophagopsis is removed from synonymy with Cerophagus and retained in the family Acaridae, while Cerophagus is transferred to the family Gaudiellidae. The genus Rhypoglyphus is considered a junior subjec­tive synonym of Cerophagopsis. The genera of Gaudiellidae are noted and the genus Trigonacoptes is considered a junior subjective synonym of Gaudiella.

Further Eastern Range Extension And Host Records For Leptoglossus Occidentalis (Heteroptera: Coreidae): Well-Documented Dispersal Of A Household Nuisance, Wayne K. Gall

The Great Lakes Entomologist

Leptoglossus occidentalis is reported for the first time from Connecticut, New York, Ontario, Pennsylvania, and Wyoming, representing an eastern range extension from Indiana and Michigan. Tsuga canadensis and Pinus mugo are added to the long list of coniferous hosts of this coreid. Approximately 233 of 316 northeastern specimens were collected inside or on the outside of buildings from August-May, confirming previous observations that L. occidentalis uses buildings for overwintering. Isolated records from Con- necticut and eastern Pennsylvania suggest human-mediated dispersal may augment its natural dispersal. The pattern of distribution records on a map of North America identifies L. occidentalis as …

The Food Plants And Distribution Of The American Plum Borer (Lepidoptera: Pyralidae), David J. Biddinger, Angus J. Howitt

The Great Lakes Entomologist

The North American geographical and host plant distributions for the American plnm borer, Euzophera semifuneralis, are reported. Literature and curatorial surveys found the plum borer to be present in 34 states in the U. S. as well as parts of Canada, Mexico, and South America. Pheromone surveys and direct observation found it to be present in high numbers in most cherry and plum orchards in Michigan and in 28 counties of the lower peninsula. A very wide host range representing 15 plant families was found, with most host species in the Rosaceae.
