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,

Mass Rearing Of The Greater Wax Moth, Galleria Mellonella (Lepidoptera: Pyralidae), For Small-Scale Laboratory Studies, M. A. Mohamed, H. C. Coppel

The Great Lakes Entomologist

A technique was developed to mass rear the greater wax moth, Galleria mellonella, economically (ca. 0.2 cents per larva exclusive of 3-5 h of labor costs per week). Mortality in the egg and early larval stages was ca. 48% whereas in later larval and pupal stages it was ca. 10% and 27% respectively. With a fecundity of 650-1120 eggs per female, and notwithstanding the high egg and early larval mortality, the procedure easily provides a self-sustaining culture with high yields of all stages.

Moths Of The Douglas Lake Region (Emmet And Cheboygan Counties), Michigan: Iii. Thyatiridae, Drepanidae, Lasiocampidae, Notodontidae, Lymantriidae (Lepidoptera), Edward G. Voss

The Great Lakes Entomologist

(excerpt)

The first list of Lepidoptera for the Douglas Lake region (Welch 1915) included 12 species in the group of five families for which 55 species are now reported. This 358% increase ronly in part the result of enlarging the' 'region" to include all of the two counties which share the northern tip of the Lower Peninsula of Michigan) compares with an increase of 356'4:- in the families Sphingidae-Ctenuchidae (Voss 1970) and 623% in the Noctuidae (Voss 1981). Only the Geometridae remain to complete recording the consider- able expansion of our knowledge of the local macro1epidopteran fauna over the past …

Establishment Of The Alfalfa Weevil Parasite Microctonus Aethiopoides (Hymenoptera: Braconidae) In Michigan, Edward B. Radcliffe, Gerrit W. Cuperus, John K. Flessel

The Great Lakes Entomologist

Microctonus aethiopoides, a braconid parasite of adult alfalfa weevil, Hypera postica, is now established in southeastern Minnesota. Releases were made near Caledonia in Houston County, in 1978 and 1979, and near Rosemount in Dakota County, in 1979 and 1980. M. aethiopoides was recovered in Houston County in 1979, a new state record, and since has expanded its range more than 40 km from the release site. Establishment in Dakota County was unexpected because of low host densities, but parasites were recovered there in 1983. Other workers have recovered M. aethiopoides in Olmstead County.

Michigan's Cooperative Forest Pest Management Program, A Team Approach To Improving Forest Management, Louis F. Wilson, Daniel G. Mosher, Gary A. Simmons

The Great Lakes Entomologist

A forest management team was organized in the late 1970's by cooperative efforts of Michigan's universities. the Michigan Department of Natural Resources, and the USDA Forest Service.The goals were to devise new technologies, transfer available technology, and service and management alternatives to forest land managers in Michigan. The program throughout has emphasized forest management rather than pest management for prevention and control of pests. Dissemination of pest management information has been of importance and new research results have gone directly to land managers for immediate use. The team participates in forest compartmental reviews and helps prescribe management plans for land …

Some Observations On Insecticide Resistance, Robert F. Ruppel

The Great Lakes Entomologist

A model for development of resistance to an insecticide in an insect population is presented. The rate of development of resistance increased with increases in the proportion of the breeding population exposed to the insecticide and with increases in the survival from exposure to the insecticide. Restricting application of insecticides to an "only if needed" basis and, within limits, dosages that assure minimal survival of the exposed insects are suggested as means of impeding resistance to insecticides. The huge gene pools represented by the large populations of pest species are assumed to maintain insecticide resistance as a continuing problem in …

Flower Associations Of Mimetic Syrphidae (Diptera) In Northern Michigan, G. P. Waldbauer

The Great Lakes Entomologist

Collections of specialized (high fidelity) mimetic Syrphidae in northern Michigan revealed 19 species associated with 18 flowering plants. Almost 97% of these syrphids were taken on seven plant species or species groups, all with conspicuous white or yellow blossoms, and all but one with aggregate inflorescences. Pastinaca sativa (Umbelliferae) is visited by many mimetic syrphids in northern Michigan but by very few in central Illinois; the opposite is true of Sambucus canadensis (Caprifoliaceae). In northern Michigan mimetic syrphids exploit a sequence of blossoming plants that more or less replace each other as the season progresses. The cooling effect of Lake …

Host-Feeding Behavior Of The House Mosquito Culex Pipiens In Northwest Ohio (Diptera: Culicidae), C. Lee Rockett, Donald A. Somers

The Great Lakes Entomologist

The human-biting behavior of Culex pipiens was investigated in northwest Ohio. The biting studies were conducted by exposing a human volunteer for 33 h at ground and 10-m height levels in a field area which contained sizeable populations of C. pipiens. No significant feeding on humans was noted and only a single specimen of C. pipiens was observed to attempt feeding. Concurrent light trap data revcaled a definite stratification preference for C. pipiens at the 10-m height level. In the laboratory, caged C. pipiens were allowed to feed on humans (l2-h period) with no positive results. Other caged specimens …

Distribution And Hybridization Of Hyalophora Columbia (Lepidoptera: Saturniidae) In Wisconsin, Leslie A. Ferge

The Great Lakes Entomologist

Hyalophora columbia (Smith) has been collected in 12 Wisconsin counties, primarily in the north-central region. The adult flight season peaks during the second week of June. Hyalophora cecropia (L.) was found to occur in many of the columbia localities, and to be active at the same time as columbia. Despite this overlap, natural hybrids were very rarely seen.

A Pyralid Moth (Lepidoptera) As Pollinator Of Blunt-Leaf Orchid, Edward G. Voss, Richard E. Riefner Jr.

The Great Lakes Entomologist

(excerpt)

As early as 1912, mosquitoes were observed bearing the pollen masses (pollinia) of the blunt-leaf orchid, Habenaria obtusata (Pursh) Richardson, in Reese's Bog, a cedar swamp at the north end of Burt Lake, Cheboygan County, Michigan, near the campus of the University of Michigan Biological Station (Dexter 1913).

Buprestidae, Cerambycidae, And Scolytidae Associated With Successive Stages Of Agrilus Bilineatus (Coleoptera: Buprestidae) Infestation Of Oaks In Wisconsin, Robert A. Haack, Daniel M. Benjamin, Kevin D. Haack

The Great Lakes Entomologist

The species of Buprestidae, Cerambycidae, and Scolytidae found in association with Agrilus bilineatus (Weber) in declining oaks, Quercus spp., in Wisconsin, were Chrysobothris femorata (Olivier) and Dicerca sp. (Buprestidae); Amniscus macula (Say),Cyrtaphorus verrucosus (Olivier), Euderces picipes (Fabricius), Graphisurus fasciatus (DeGeer), Neodytus acuminatus (Fabricius), Sarosesthes fulminans (Fabricius), and Xylotrechus colonus (Fabricius) (Cerambycidae); and Monarthrum fasciatum (Say), Monarthrum mali (Fitch), Pseudopityophthorus minutissimus (Zimmerman), and Xylaterinus politus (Say) (Scolytidae). In general, weakened oaks were first attacked by A. bilineatus. and at times that same year by C. femorata. G. fasdalus, and P. minutissimus. Infestation by M.fasciatum, M. mali, and X. politus began …

Effects Of Various Split Developmental Photophases And Constant Light During Each 24 Hour Period On Adult Morphology In Thyanta Calceata (Hemiptera: Pentatomidae), J. E. Mcpherson, T. E. Vogt, S. M. Paskewitz

The Great Lakes Entomologist

Rearing immatures of Thyanta calceata in a range of split photophases during each 24 h period and in constant light showed that the adult dimorphic response in color and pu- bescence could be produced; individuals reared in photoperiods in which each scotophase was at least 2 h in length generally developed into the fall/spring morph.

Seasonal Flight Patterns Of Hemiptera In A North Carolina Black Walnut Plantation. 7. Miridae, J. E. Mcpherson, B. C. Weber, T. J. Henry

The Great Lakes Entomologist

The seasonal flight patterns of 79 species of Miridae collected in window traps in a North Carolina black walnut plantation are described. Flying height distributions and seasonal flight activities of Deraeocoris nebulosus (Uhler), Keltonia sulphurea (Reuter), Lygus lineolaris (Palisot de Beauvois), Plagiognathus politus Uhler, and Reuteroscopus ornatus (Reuter) are considered in detail.

Collections Of Hibernating Ground Beetles (Coleoptera: Carabidae), Gary A. Dunn

The Great Lakes Entomologist

(excerpt)

The mild, snowless winter weather of late December 1982 and early January 1983 made it easy to obtain litter and soil samples for extraction of overwintering ground beetles. Collections of this nature are desirable in order to positively confirm the hibernating status of Michigan carabid beetles. As an added benefit, the collections also produced several specimens of rare species which had not been previously collected by other methods (blacklighting and hand collecting) in the same areas during the spring and summer of 1982.

First Record Of The Mosquitoes Aedes Dupreei Psorophora Horrida, And Psorophora Mathesoni (Diptera: Culicidae) In St. Joseph County, Indiana, Roger S. Nasci, David B. Taylor, Leonard E. Munsterman

(excerpt)

Adult females of Aedes (Ochlerotatus) dupreei (Coquillett), Psorophora (lanthinosoma) horrida (Dyar and Knab), and Psorophora (Janthinosoma) mathesoni (Belkin and Heinemann) were collected on 18 and 19 June 1981, in an oak woodlot in South Bend, Indiana.

Status And Management Of Pyrethroid Resistance In The Predatory Mite, Amblyseius Fallacis (Acarina: Phytoseiidae), B. A. Croft

The Great Lakes Entomologist

Low levels of (5-15 fold) resistance to synthetic pyrethroid (SP) insecticides occur in unexposed apple orchard populations of the predatory mite, Amblyseius fallacis Garman. Permethrin resistance in one strain has been elevated 60--500 fold by selections in green- houses. Multiple resistances to DDT and azinphosmethyl are present and cross-resistance to SP-related compounds is generic at 10--250 fold. Permethrin resistance appears due to both hydrolytic esterase and knock down resistance mechanisms. Permethrin resistance appears to be polygenic and more recessive than dominant; it is unstable in the presence of high densities of susceptible immigrant types, but is reasonably stable in the …
