Insect Pests Associated With Birdsfoot Trefoil, Lotus Corniculatus, In Wisconsin, Mark S. Wipfli, John L. Wedberg, David B. Hogg, Thomas D. Syverud

The Great Lakes Entomologist

Insect surveys taken during 1984-1986 in Ashland and Bayfield Counties of northern Wisconsin revealed that several potential insect pest species were common in birdsfoot trefoil, Lotus corniculatus. Three plant bug species, including: the tarnished plant bug, Lygus lineolaris: alfalfa plant bug, Adelphocoris lineolatus; and Plagiognathus chrysanthemi were abundant in most sampled fields. P. chrysanthemi was the most abundant species, was only present in the northern locations, and completed one generation per year. A. lineolatus and L. lineolaris were second and third in abundance, respectively, and completed two generations per year. Population levels of the potato leafhopper, Empoasca fabae. …

Bacteria As Ovipositional Attractants For Aedes Aegypti (Diptera: Culicidae), Dana Hasselschwert, C. Lee Rockett

The Great Lakes Entomologist

The effectiveness of selected bacterial species as ovipositional attractants for Aedes aegypti was compared. Bacterial washes, in glass containers, were utilized as ovipositional substrates and subsequent egg counts determined the degree of ovipositional attractiveness. Among others, Bacillus cereus and Pseudomonas aeruginosa were noted as being effective attractants. It was concluded that A. aegypti displays discriminatory behavior in selecting individual bacterial species for oviposition.

Attraction Of Acorn-Infesting Cydia Latiferreana (Lepidoptera: Tortricidae) To Pheromone-Baited Traps, J. W. Peacock, S. L. Wright, J. R. Galford

The Great Lakes Entomologist

Males of acorn-infesting Cydia latiferreana are attracted to an equilibrium mixture of the four isomers of 8, 10-dodecadien-l-ol acetate, the virgin female-produced pheromone. Trap height relative to the height of trees in which traps are placed seems to be a significant factor influencing moth catches at attractant-baited traps. In an oak woodlot and in an oak nursery, catches of male moths were greater in traps placed near the upper periphery of the canopy than at traps deployed at lower levels in the tree. Practical application of pheromone-baited traps in a forest situation will require further study on lure formulation and …

Pheromone Lures To Monitor Sparse Populations Of Spruce Budworm, Choristoneura Fumiferana (Lepidoptera: Tortricidae), David G. Grimble

The Great Lakes Entomologist

Four types of spruce budworm pheromone lures were field-tested in sparse spruce budworm populations in Maine. BioLures® with constant pheromone emission rates less than 1.0, ca. 1.0-1.5, and ca. 15.0 micrograms of pheromone per day were compared to polyvinyl chloride (PVC) lures with rapidly decreasing pheromone emission rates. Mean trap catch was roughly proportional to lure emission rates. All lures continued to catch moths over the entire flight period but moth catches with the three lowest emission-rate lures were judged to be too low. BioLures with the highest emission rate (15.0 micrograms of pheromone per day) showed the lowest variability …

Observations On The Puddling Behavior Of The Canadian Tiger Swallowtail Butterfly, Papilio Glaucus Canadensis In Northern Michigan, J. Mark Scriber, Matthew P. Ayres

The Great Lakes Entomologist

(excerpt)

The occurrence of "puddling" behavior in Lepidoptera has been reviewed by M. J. Norris (1936) by J. A. Downes (1973) and by P. H. Adler (1982). Butterflies have been previously reported on mammalian dung, urine, perspiration, saliva, salt, blood, campfire ashes, aphid honeydew, tree sap and animal carrion. The rarity of female puddling in butterflies, particularly the tiger swallowtail (Papilio glaucus) has been recently addressed by two studies (Berger and Lederhouse 1985, Scriber 1987).

Malathion Resistance In Larvae Of Some Southern Minnesota Populations Of The Indianmeal Moth, Plodia Interpunctella (Lepidoptera: Pyralidae), Infesting Bulk-Stored Shelled Corn, W. A. Sumner Ii, P. K. Harein, Bh. Subramanyam

The Great Lakes Entomologist

Larvae of 21 field collected populations of the Indianmeal moth, Plodia interpunctella, infesting stored shelled corn in southern Minnesota were tested for their susceptibility to malathion in the laboratory. A population that was a composite of the 21 populations and a malathion susceptible population were also tested for their susceptibility to malathion, pirimiphos-methyl and chlorpyrifos-methyl. Comparison of the LDso values of the field populations with the malathion susceptible population indicated that the field populations were ca. 33- to 625-fold resistant to malathion. The composite field population was ca. 243-fold resistant to malathion, and this population was 3.2-fold cross-resistant to …

Courtship Behavior In Habronattus Captiosus (Araneae: Salticidae), Bruce Cutler

The Great Lakes Entomologist

Courtship display of Habronattus captiosus involves several behavioral elements common to other members of the Habronattus coecatus species group. The one unique element is vibration of the patellae when raised over the opisthosoma. Male-male interactions included an agonistic display and grappling. Fourteen male-female interactions were observed, which exhibited various combinations of display elements. There was one successful mating and one case of cannibalism by a male.

Chrysochus Auratus (Coleoptera: Chrysomelidae) Absolved As Pecan Pest, Charles E. Williams

The Great Lakes Entomologist

Chrysochus auratus, the dogbane beetle, has been erroneously implicated as a pecan defoliator in the early literature. Alternative scenarios suggest other chrysomelid species that may have been responsible for the defoliation.

Use Of Baited Pitfall Traps For Monitoring Pales Weevil, Hylobius Pales (Coleoptera: Curculionidae), Kenneth F. Raffa, David W. A. Hunt

The Great Lakes Entomologist

Pitfall traps baited with ethanol and turpentine serve as an effective tool for monitoring pales weevil (Hylobius pales) populations. Males and females are equally attracted to this bait. Neither component alone showed any attractiveness. The presence of a pine stem for weevil feeding does not affect the number or sex ratio of captured weevils. The potential of using attraction to baited traps as a sampling method for pales weevil is discussed.

Spring Season Survey Of The Urban Blowflies (Diptera: Calliphoridae) Of Chicago, Illinois, Donald L. Baumgartner

The Great Lakes Entomologist

During May 1980, 1165 blowflies of 12 species were trapped on chemically enhanced rat carrion baits in a dense urban setting in Chicago. In descending order, Cynomyopsis cadaverina, Lucilia sericata, and Phormia regina were the most abundant species recovered (92% of total). These results are contrasted with other nearby blowfly surveys.

Araphe Carolina In Illinois (Hemiptera: Largidae), John K. Bouseman

The Great Lakes Entomologist

(excerpt)

Araphe carolina (Herrich-Schaffer) is a little-known species that has been recorded "from North Carolina south to Florida, thence west through Tennessee to Arizona and Baja California" (Halstead, 1972). Froeschner (1944) characterized it as a "scarce species" in recording it from five counties in the Ozark Region of southern Missouri. The purpose of this note is to provide the first records of A. carolina in Illinois and incidentally to provide the first record of any largid bug in the state.

Terricolous Spiders (Araneae) Of Insecticide-Treated Spruce-Fir Forests In West-Central Maine, Daniel J. Hilburn, Daniel T. Jennings

The Great Lakes Entomologist

Spiders of 12 families, 42 genera, and at least 62 species were captured in linear-pitfall traps placed in insecticide-treated (Sevin-4-Oil®, Dipel 4L ®, Thuricide 16B®) and untreated spruce-fIr forests of west-central Maine. Species richness per family ranged from 1 (Theridiidae, Araneidae, Salticidae) to 19 (Erigonidae). Most trapped species were web-spinners (67.2%); most trapped individuals were hunters (75.2%). Lycosidae accounted for 66.1 % of all (n = 887) captured spiders. Total trapped spiders varied among insecticide treatments, sampling dates, and study sites. However, comparison of mean prespray and postspray trap catches indicated no significant reduction (ANOVA, ANCOVA, P 0.05) in terricolous …

Biology, Injury, And Control Of The European Needle-Bending Midge (Diptera: Cecidomyiidae) On Scotch Pine In Michigan, Louis F. Wilson, Frank J. Sapio, Gary A. Simmons

The Great Lakes Entomologist

Contarinia baeri is univoltine in Michigan. Adults emerge in spring, and females deposit eggs in small clusters in the sheaths of new-growth pine needles. Larvae hatch shortly thereafter and there are three larval instars. Larval feeding causes the needles to at first droop, discolor, and eventually drop, reducing the quality of Christmas trees and occasionally killing shoots. Larvae overwinter on the ground in cocoons, and pupate in spring. Adults were suppressed (> 75% control) with formulations of Pydrin® (fenvalerate) and Tempo® (cyfluthrin) applied within a week after adult emergence.

The Pest Status Of Yellowjackets In Ohio (Hymenoptera: Vespidae), Kenneth J. Stein, Dana L. Wrensch

The Great Lakes Entomologist

Since 1975 in Ohio, there has been an escalation in the number of complaints and inquiries regarding yellowjackets (Vespula and Dolichovespula spp.) to the Ohio pest control operators, the Ohio Cooperative Extension Service (OCES) County Agents and the OCES Entomologists at the Ohio State University. A survey was distributed in May 1985 to both groups in order to determine the pest status of yellowjackets in Ohio. The results of this survey strongly suggest that yelIowjackets in Ohio are largely an "economic pest", with most economic disturbances associated with homeowners, outdoor businesses, and outdoor recreational facilities.

New Host Records And Developmental Notes On The Pear Slug Caliroa Cerasi (Hymenoptera: Tenthredinidae), Feeding On Cotoneaster And Chaenomeles Species., Kenneth F. Raffa, Gregory L. Lintereur

The Great Lakes Entomologist

The pear slug. Caliroa cerasi was collected and reared to adulthood on flowering quince and three species of Cotoneaster. This is the first record of C. cerasi attacking any member of the genus Chaenomeles and the first confirmation of feeding on Cotoneaster in North America. Adult emergence, oviposition, and larval development were evaluated under both laboratory and field conditions. Females lay an average of 48 eggs, with about two-thirds of the oviposition occurring during their first 24 hours. A method for monitoring adult emergence in the field was developed.

Seasonal Occurrence Of Pine Root Collar Weevil, Hylobius Radicis (Coleoptera: Curculionidae), In Red Pine Stands Undergoing Decline, Kenneth F. Raffa, David J. Hall

The Great Lakes Entomologist

A trapping scheme was devised for sampling the pine root collar weevil, Hylobius radicis, in mature red pine plantations in Wisconsin. Adult weevils were trapped throughout the 1986 field season, and the method appears sensitive enough to discern temporal and spatial trends. The number of weevils caught was higher in stands symptomatic of the general condition currently labelled Red Pine Decline and Mortality. In some stands there was a strong tendency for trap catches to be particularly high near certain trees. Seasonal trends and sex ratios were compared with published reports of H. radicis activity in Michigan.

Field Monitoring Of X-Disease Leafhopper Vectors (Homoptera: Cicadellidae) And Infected Chokecherry In Michigan Peach And Cherry Orchards, Kirk J. Larsen, Mark E. Whalon

The Great Lakes Entomologist

Populations of leafhopper vectors of X-disease, a major disease problem of the Michigan peach industry, were monitored by yellow sticky board traps and sweepnet samples during 1985 and 1986. Abundance of known leafhopper vectors varied throughout the stone fruit belt of Michigan, with Paraphlepsius irroratus common in the southwest Lower Peninsula, but representing 73.1 % of all known vectors found. Other commonly found vectors included Scaphytopius acutus (22%), Colladonus clitellarius (1.5'k). and Norvellina seminuda (3.4%). Yellow sticky boards were the best monitoring method used. accounting for 90.3% of all vectors captured. The appearance of X-disease symptoms on chokecherry throughout the …

Insecticide And Growth Regulator Effects On The Leafminer, Liriomyza Trifolii (Diptera: Agromyzidae), In Celery And Observations On Parasitism, E. Grafius, J. Hayden

The Great Lakes Entomologist

The effects of different insecticides were compared on survival and development of the leafminer, L. trifolii, in celery in Michigan and parasitism was assessed in this non- resident population. Avermectin, thiocyclam, and cyromazine effectively controlled L. trifolii larvae or prevented successful emergence as adults. Moderate to high levels of resistance to permethrin and chlorpyrifos were present. Avermectin caused high mortality of all larval stages and no adults successfully emerged. Thiocyclam caused high mortality to all larval stages, but did not affect adult emergence from the surviving larvae. Cyromazine acted most strongly against early stage larvae before visible mines were …
