Aquatic Hemiptera Of Wisconsin, William L. Hilsenhoff

The Great Lakes Entomologist

About 59,000 aquatic Hemiptera were collected in Wisconsin, most of them in the last 15 years. These include three species of Belostomatidae, 48 species of Corixidae, one species of Naucoridae, four species of Nepidae, nine species of Notonectidae, and one species of Pleidae. The riparian Gelastocoris oculatus was also found. Species keys for adults are provided along with notes on identification, habitat, biology, distribution, and abundance. Most species reached peak abundance in late summer and autumn and overwintered as adults, but seven species apparently overwintered as eggs. Most lentic species flew to streams or larger len tic habitats to overwinter. …

Flowers Associations And Mating Behavior Or Its Absence At Blossoms By Spilomyia Spp. (Diptera, Syrphidae), G. P. Waldbauer, Arthur W. Ghent

The Great Lakes Entomologist

(excerpt)

Syrphid flies of many species visit blossoms to obtain nectar and pollen (see Waldbauer 1983 for referencesl. Many of these syrphids, in common with other insects (Parker 1978), also find mates at the blossoms. Males of these syrphid species make aerial patrols of inflorescences frequented by females, alternating these patrols with sitting on foliage. l11ey pounce on or chase insects of various species and swiftly initiate copulation with can specific females (Collet and Land 1975; Maier 1978; Maier and Waldbauer 1 979a,b).

A Maple Wood Wasp, Xiphydria Maculata, And Its Insect Enemies (Hymenoptera: Xiphydriiade), Mark A. Deyrup

The Great Lakes Entomologist

A xiphydriid wood wasp, Xiphydria mandata, is very common in branches ofAeer spp. in Indiana. and is frequently the proximate cause of branches falling from shade trees. X. maculata is attacked by seven parasitoids: Alliaells bllrquei (Aulacidae), A. digitalis, Rhyssella nitida (Ichneumonidae), Xiphydriophagus meyerinckii (Pteromalidae), Coeloides rossicus betulae (Braconidae), Spathills elegans (Braconidae), and Orussus sp. (Orussidae). The latter three parasitoids prior to this study had no confirmed hosts; Xiphydriophagus is new to N. America. This parasitoid complex is compared with that of the Palaearctic Xiphydria camelus, showing a series of pairs of closely related Palaearctic and Nearctic forms.

Effect Of A Hay Mulch And Of A Companionate Planting On Cabbage Pest Populations, W. S. Cranshaw

The Great Lakes Entomologist

Cabbage crop environments were modified by either use of a hay mulch or intercrop- ping with "companionate" plants (nasturtium, thyme, and rosemary). A temporary reduction in egg and larval numbers of imported cabbageworm (Artogeia rapae L.) occurred on mulched plots. This effect disappeared later in the season as the plants grew large and coyered the mulch. On some interplanted plots, temporary increases in cabbage looper (Trichoplusia ni Hubner) larvae and decreases in imported cabbageworm eggs were noted. Hov.'Cver. on most dates, there was no effect of interplanting on pest populations. The general lack of effects on cabbage insect pests …

Possible Colonization Strategies Of Some Carabid Beetles Inhabiting Stream Shores (Coleoptera: Carabidae), Paul M. Holeski

The Great Lakes Entomologist

Certain species of insects appear to be better adapted by virtue of their particular strategy to survive disruption of the habitat than do others sharing the same area. Bembidion impotens, a carabid beetle, was especially successful in rapidly recolonizing a defaunated stream shore and in maintaining a relatively high population when the habitat was subjected to normal but severe disruption.

The First Record Of Delphacodes Havanae In The United States (Homoptera: Fulgoroidea: Delphacidae), Stephen W. Wilson

The Great Lakes Entomologist

(excerpt)

Delphacodes havanae Muir and Giffard has been reported from Guyana, Guatemala, Cuba (Muir and Giffard, Bull. Hawaiian Sugar PI. Assoc. 15:1-53, 1924) and Puerto Rico (Caldwell and Martorell, 1. Agric. Univ. Puerto Rico 34:133-269, 1950).

New State Records Of Cerambycidae From Michigan (Coleoptera), D. C. L. Gosling

The Great Lakes Entomologist

(excerpt)

Previously published lists of Cerambycidae from Michigan (Gosling 1973, Gosling and Gosling 1977) recorded 225 species from the state. Reassignment of Trachysida brevifrons (Howden) as a subspecies of Trachysida aspera (LeConte) (Linsley and Chemsak 1976) reduced the total by one. Recent collecting in St. Joseph County in southwestern Michigan and Marquette County in the Upper Peninsula has added three species to those already known from Michigan.

Spatial Distribution Of Jack Pine Cones And Those Attacked By Insects, Aunu Rauf, D M. Benjamin

The Great Lakes Entomologist

The middle crown and south quadrant of 6-m-tall jack pines, Pinus banksiana Lamb., produced significantly more cones than the rest of the tree. The number of cones attacked by Eucosma monitorana Heinrich was also highest in the middle crown and south quadrant. Laspeyresia toreuta (Grote) attacked the most cones in the middle crown. A positive, linear correlation existed between the number of cones attacked by inseets and cone abundanee per tree, indicating a response of the insect population to inereased food supply.

Addendum To The Inventory Of Stored Grain Insects In Michigan, Robert F. Ruppel

The Great Lakes Entomologist

Additional species of stored grain insects have been found in Michigan since the inventory of such pests was published (Ruppel 1977). The additional species were primarily found through a study of insects in county elevators (Russell 1980) and through examinations of infested grains submitted for identification. The names of these insects are given in Table 1. The brown spider beetle and murmidius beetle were found in infested small grains, the European grain moth was found in stored soybeans and in elevator trash. and the others were found in elevator trash.

Insecticide Effects On Normal Development And Hatch Of Embryos Of Paratanytarsus Parthenogeneticus (Diptera: Chironomidae), Richard L. Anderson, Pam Shubat

The Great Lakes Entomologist

Simple, low cost methods are needed to determine the effect of pesticides on non-target aquatic organisms. In this report, embryos of Paratanytarsus parthenogenetic us were exposed from deposition to hatch to five pesticides. Four of the five pesticides affected development or hatch only at concentrations which exceeded 96-h LC50 values of other non-target invertebrates. One pesticide, fenitrothion, affected hatch at 13 Ilgll which is similar to 96-h LC50 values for other aquatic invertebrates. Because of the low sensitivity of the embryo to pesticides, this method may not be a useful pesticide screening test for non-target invertebrates.

Observations On North Dakota Sponges (Haplosclerina: Spongillidae) And Sisyrids (Neuroptera: Sisyridae), Ralph D. Stoaks, Joe K. Neel, Richard L. Post

The Great Lakes Entomologist

Factors influencing occurrence, distribution, and ecology of sponges and sisyrids are discussed, with emphasis on northeastern North Dakota. New state records for North Dakota sponges, Eunapius Jraguis Leidy and Ephydatia fluviatilis L. and the sisyrids, Sisyra vicaria (Hagen) and Climacia areolaris (Hagen), and new county records for C. areolaris in northwestern Minnesota and Eunapius fragilis in northeastern North Dakota are reported. A rare association of the parasite, S. vicaria with the host, Ephydatia fluviatilis is also reported. Some physicochcmical relations of Eunapius fragilis found in the Forest River, North Dakota, are discussed.

A Note On The Nesting Of Mimesa Lutaria (Hymenoptera: Sphecidae), Frank E. Kurczewski, Mark F. O'Brien

The Great Lakes Entomologist

Five nests of Mimesa lutaria (Fabricius) were excavated and studied at Cranberry Lake, S1. Lawrence County, NY. The nests were shallower than those of other species previously studied, yet the tumuli were large and conspicuous. An average of about 11 adult and nymphal cicadellids were stored in a cell, except for one cell that held five Delphacodes sp. (Delphacidae).

Simulation Of How Jack Pine Budworm (Lepidoptera: Tortricidae) Affects Economic Returns From Jack Pine Timber Production In Michigan, Jan P. Nyrop, Jeffrey T. Olson, Daniel G. Mosher, Gary A. Simmons

The Great Lakes Entomologist

The impact of jack pine budworm on economic returns from jack pine timber production in Lower Michigan and management actions that might be taken to reduce this impact were evaluated with a simulation model. Results indicate that current jack pine rotation ages arc excessive and should be reduced. Insecticide application is not a viable strategy for reducing jack pine budworm impact.

Spruce Budworm Weight And Fecundity: Means, Frequency Distributions, And Correlations For Two Populations (Lepidoptera: Tortricidae), Nancy Lorimer, Leah S. Bauer

The Great Lakes Entomologist

Pupal weights and fecundities of spruce budworm from Minnesota had different means, coefficients of variation, and frequency distributions than spruce budworm from New Hampshire. The two variables were correlated in one of the populations but not the other.

Reproductive Compatibility Within And Among Spruce Budworm (Lepidoptera: Tortricidae) Populations, Nancy Lorimer, Leah S. Bauer

The Great Lakes Entomologist

Spruce bud worm moths collected as larvae from two species of host trees in four populations were mated in single pairs in two years. In 1980 but not 1981, more of the intra-population matings than the inter-population matings were fertile. Host tree origin was not a significant factor in the level of sterility.

An Assessment Of Gypsy Moth Eradication Attempts In Michigan (Lepidoptera: Lymantriidae), Steve H. Dreistadt

The Great Lakes Entomologist

Michigan's infestation of gypsy moth, Lymantria dispar, extends over 600,000 acres, First discovered in Michigan in the 19505, gypsy moth was reportedly eradicated through the use of DDT then reintroduced in the 1970s, Substantial circumstantial biological evidence, however, points to the probability that gypsy moth has resided continuously in Michigan for over 30 years, Environmental factors may be largely responsible for containing Michigan's gypsy moth popUlations,
